AC also gives the rod a cooling cycle that allows you run a higher amperage without overheating the electrode. AC is also less expensive because you are not using the rectifier in the machine, when you weld with rectified power you use up about 25% more power at any amperage.
modern inverter machines work different. they always rectify power and then convert it to whatever you want via mosfets. (solid state switches, that switch on and of more than 10.000 times a second).
@@bigdave6447 if its a sine wave output, most inverter machines run square wave ac. which makes it 100% of dc. minus the mosfet switching losses to be precise. more precisely, if the machine simulates that sine wave, that would make it .707, you still would have to substract the switching losses, since you still get a square wave pwm with a sine wave duty cycle :)

7024,5/32 on the outside seams. What a nightmare, 1 welder on the inside had to stay ahead of 2 wélders on the top of the outside while the tank was turning on a set of rolls and ventilation system definitely not adequate, after a couple rods on the inside you could not see anything until you start the next rod. 210barrel.The 100 barrel shop was much more efficient and easier on your lungs. I worked by myself on afternoon shift and the fóreman was around occasionally but only 1 seam to be welded on the inside with both ends of the tànk open. 1/4 7024 was just for the outside and he is right about running slightly 10° down hill, you could get 5' beads from 1rod.If you run too far down hill and you couldn't keep the slag behind you get pinhole effect.

So down to earth and easy to watch without all the uptight "I'm a pro" b.s. Thank you for all of the great information. I would love to be good enough to do custom fab work one day.
At one point watching this video I went to flip my hood down just as bob was about to start welding. Great teacher does a good job immersing the viewer!
I haven’t welded in probably 15 years, took welding in HS 20yrs ago got so discouraged never really pursued it. (Short of a job making horse corrals). Now I’ve been bitten by the welding bug and watching a lot of these vids and Jody’s vids. Both have been so much more informative than I remember from HS.
I did my mechanic apprenticeship on a city workshop, next door in the same building was an old school blacksmith. He did all the fabricating/metal repairs etc for the machinery etc. When laying down hardfacing on worn grader blades he would use 2 welders at the same time, strike arcs and lay the rods and holders (not the clamp one, but the ones you put the rod in and twist handle to lock) down, stand back and watch them both go. The object was to build back the worn cutting edges (early 1980's was cheaper to do this than replace blades every few weeks on the big graders)
Bob is incredible, so helpful. He's got this Billy Bob Thornton style which is terrific. Don't ever change any aspect of this program, it's the best out there. :) Thank you for your hard work.
Best decision I ever made was getting a powerarc welder and learning how to weld from youtube videos. It is such a great life skill to have. I only wish I had done it earlier in life.
love all your videos!!!! I've been slowly teaching myself by watching all your videos and enjoying every second of them. I so wish I was able to take one of your classes because I know with hands on experience with an instructor like you I would become one hell of a welder and have a blast doing it. Thank you so much for taking the time to share your knowledge with the world for people like me who rely on your videos to learn all the different techniques and knowledge needed to pressue a path of welding, while being entertained at the same time!
Thanks for the support, Corey. We will be doing more classes in different locations. We will announce them in the forum, so be sure to register over there. www.weld.com/welding-forum
Learning fundamentals of AC stick welding was important when I went to welding school. At that time AC stick rod welding equipment was the only thing a poor boy could afford. After you graduate welding school the first thing you do is buy yourself the best welder you can afford so that you can start making money out of your own shop or basement or where ever you can. Tuition for any good vocational welding school is expensive and you will need to pay those student loans. When you teach someone to weld with a buzz box you teach someone to feed themselves!
Bob, I really enjoy your videos. I really like welding with 6010. I think it is the welding rod of real men. Recently I saw some pictures of 6010 caps that were LACED. That really impressed me. You being a long time welder may have learned that technique. I for one with only two years of welding training and being 81 years old would be pleased to no end if you would show how that is done during one of your excellent videos. Thank you Sincerely, Walter Luikey The oldest active Union Millwright Apprentice in the USA
Walter, congratulation!! Respect sir. I remember all those laced 6010, 7010 caps too. Some were big old figure 8's. We have some outside our building on gas lines that were done probably back in the 60's. I doubt many would know what we're talking about.
When I was in welding school in the early 80's we started out with 1/8 6010's and 7018's. Everybody hated the 6010's because they like to stick. But they loved the 7018's because you could drag them and make a nice looking bead, and the slag came off so easy. But our instructors said you like the 7018's now, but when you get more experience and become better welders, you will appreciate what the 6010 can do filling gaps and open roots.
Bob Moffatt In my 20s and I don't even know what I don't know. 😞 I just took welding as part of my carpentry apprenticeship and I am fascinated by how much science is a part of it. Anyway, I really hope you old guys record the things of the past in video or writing to be shared so the info isn't lost in my and later generations.
I have an ac/dc ark welder and no training. Wish I found your videos a long time ago. There is so much I don't know but I can come here and learn. Thank you very much! 👍
I been doing a lot more stick welding lately after a few months break doing mostly TIG. I notice that going back to stick (welding gate hinge brackets on steel fence pipes to keep the deer out of my Wife's garden) I was lightly holding the electrode about 3 inches back from the end with my non dominant hand and resting my forearm on the work piece. This allowed me to get much more comfortable and guide the end of the rod. Its hard to explain but my weld quality went way up while the rod was long.
Well for the question about one of the advantages of using A/C for stick welding: It eliminates Arc blow because the current is alternating from E(-)/E(+) at the rate of whatever frequency (in Hertz) the machine is set to. Bob here can adjust it on that machine, but that’s a rare bird, and so is the machine 😁
Oh my days never laughed so much for ages such a shame to read that Bob passed away these are old videos now truly brilliant to watch and learn from my name's Dean my partner's account is attached to Google and TH-cam
I have always been a mechanic or production assembler. That is until 3 weeks ago. I got a job with a great company looking for a welder. I talked a good game and did a few passes with .045 wire on a mig and got the job. I am doing great there because of your videos. I have watched most of your videos several times over and want to thank you for sharing your life of knowledge. I couldnt have made it without your instruction.
"Today Bob will demonstrate the characteristics of different stick electrodes. He may even do some gas welding.." But seriously - I've been welding for a long time, and these demonstration/ tutorials are great.Some stuff I just plain forgot, and some I never knew.
Love. Those. Bloopers. This channel is excellent and you guys are doing a great job. I'm going to be teaching myself how to weld with an old Lincoln buzz box. You folks have been very informative. Thank you.
(Why AC?), I think historically there was also the issue of wanting to use AC-only transformer machines. At one time you needed a mass of rectifiers, or some amazing rotating dynamo. I wish people had kept more of these historic welding machines around! Really enjoying all these videos, and the 7024 one-piece slag was impressive. Good stuff!
I have recently gotten pretty addicted to watching your TH-cam channel. I have the opportunity to weld here and there at work just for the hell of it and I do so anytime I get a chance. I'm self-taught and I would say I can run a pretty nice bead for someone who has had zero teaching or anyone showing me what to do. I love the videos it is teaching a lot to someone like me who does not have someone to teach them but I have the opportunity to stick weld and I take it
Very nice video Bob. I love Your humor. "Get to know Your rods" is the best advice. Using the different rods on the right polarity and in the right positions will make so much difference to the quality of the weld. The other one is. Practice, practice, practice, practice,........and then some more practice. I will be runnning a lot of beads this weekend just because I love it and it keeps me in shape.
@@FishFind3000 The first thing is setting and learning the machine also control heat with the angle and arç distance and speed so you can almost pick up a lead and already strung out in a power plant, they run almost strictly 7018 on mild and abrasive resistant steel, jalloy is hardened for abràsiveness from the coàl.Its painted green ón the edge bécause hardened steel is brittle, it's quenched at a làrger grain structure, it's harder steel and less flexible. You have to be able to identify it so someone doesn't make D rings or lift lugs out of it and get someone killed or injured.
Have you ever used the "torpedo" welders that the government used in the shipyards during WW2. It was an AC motor driven type that ran another armature for welding. Around my area there are literally hundreds of them left over from the war still in use. Very smooth arc and a joy to use. Lincoln also made one that looked like R2D2 that stood upright. and was a small simple welder that ran really nice also, It was a motor driven type just like the torpedo welder but much smaller.
Just started welding a little over a month ago, and I love it. Enjoying the videos Bob, we also watch some of your videos in class as well. Very helpful
I learned how to weld on an old craftsman buzzbox when I was 8 yrs old been sticking stuff together ever since saved my ass more times than I can count I wouldn't be where I am without this skill. Good content Bob excellent video brought me back to the good old days tryin to burn whatever I had!!!
Thanks so much for the videos Bob. I bought the latest version of this AHP having never touched a tig or stick welder and only spending about three hours with a flux core machine. I’m having a blast learning and your videos are a great help to beginners like me.
Iono sir, but you are a great and cool welder and a great teacher. I'm getting into welding for hobby work. Watching all your videos surely helpful! Thanks for your time making these awesome videos! Forgot to say, watching you teaching about welding is very satisfying!
He cant hear it because the frequency is being recorded and Amplified with the camera microphone. Test this by grabbing your phone putting a Milwaukee or dewalt battery on a charger and hit record on your phone it should pic up a frequency that you cant hear without it....
Those that weld with various machines will know what was meant. The welder power supply is an inverter type not a traditional transformer /rectifier, so on ac welding a 60hz arc will sound quite different between the two types. Also the first welds done on ac were a higher frequency than usual, a sound usually found welding aluminium with tig.
And lastly check the table you're on LOL. Love your videos and content in my first year of welding at 39 years old and you guys are so influential and helpful with your content
Total newbie to welding. Never ever done it in my life until a month ago when I made 6 small spot welds (that are horrible I'm sure). Thanks for making this video explaining a bit about the rod numbers. I got a stick welder that I hope to learn a little bit so that I can fabricate small easy things. Looking forward to learning how to use it and to weld properly. Then I hope to advance to TIG so I can do a little bit of automotive welding for my hobby projects. I'm already fascinated by this.
Horrible spot weld or not, you tried, that's a start to improve on an build from. Give yourself more credit, keep watching Mr. Moffat, don't matter if the video is not on stick welding, you are going to learn something that will apply to stick welding an don't try to learn all forms of welding at once, focus on what you are most interested in first, take your time an as Mr. Moffat says "Keep it simple.". I'm at the learning point, no ppe or equipment because of the economic crisis, it's not a race.
2:40. I bought a Hone brand welder from Amazon, their arc welder. It was $84. I read reviews and a steam fitter used the welder to do large steel water pipes at work, commercially. He said it welded just as good as a Miller. So I bought one. And indeed, the arc is so smooth and the starting voltage is around 73 volts, no load. The welder produces such a smooth arc, it sounds like a steady hissing air, and the arc is rock solid, even if you turn the amps down 19 amps on the machine, with 240 volts input power, with 3/32 6013 rod. Read the reviews, but the new inverter DC welders, produce an extremely smooth arc, and it makes it a lot more enjoyable to weld. The inverter machines also are programmed with "arc force" to increase current if you dig the electrode in, so it's easier to maintain the proper weld bead, even if you accidentally get too close to the metal. For $84, everyone should learn stick welding.
i got a amico off ebay the 220 stick and lift tig did some 1/8 6013 as per bobs recommendations, brilliant!!! so smooth im afraid of welders typically, such a smooth arc and yes that arc force is AMAZING im no welder but my welds turned out absoluely aazing!! so true!!!
@@vickiesells8652I bought an Amico from a local guy (for a cheap plaything) knowing it will not run on 115, only on 240. Can you or anyone tell me how to fix it?
Right on man. Thanks for this. Y’all got good science vocalizing goin on, and I’m a HUGE fan of teaching ambidextrous welding. It should be an early skill path. You never wanna be 30 minutes into a setup and realize y’all gotta come at it from a different angle cause you can’t use your other hand.
I think this is my 3rd time watching this video, so much good info. Just ordered an ahp 201. Hope to get by the end of the month with all the craziness going on. Can’t wait to start glueing some metal together, thanks guys!
If I had a teacher like Moffat I'd be a pro at about now. Been welding for more than a decade, still have so much to learn. Would sure appreciate more videos from Bob - keep 'em coming, please. Thank you.
Great video, always learn something new. It's one thing seeing how things are done, it's a totally different matter knowing why things are done that way.
a nother great video Bob love your straight forward honest approach and your dry sense of humor you should do a blooper video I bet it wood be great please keep the videos coming
can we see a cut and etch of some 7014? we have a big 500 amp Lincoln ac idelarc and 7014 is our workhorse rod. We do a lot of heavy equipment repair and I've never had a failed repair. Just curious as to how much less penetration I get with 7014 as to 7018 or 6010 or even 6011. Best regards Brett
I’ve had the same issue with 6011 as you did with 6010. I bought a tiny $170 80amp welder just for fun and it’s the first time I’ve welded since high school, so those two things may apply in my case, but I had a hard time keeping it from going out on me.
I am probably too old to be a student but still learning. I am doing vertical welding using 6011 AC. I learn that I am using the wrong electrode. Perhaps a 7018 is indeed the electrode that l should be using at about 105 amp. I will give it a go tomorrow.
I would imagine with ac the advantage would be a balanced heat, not punching through, may keep heat balanced more on thinner stuff, and would also help with arc wander and arc blow.
Bob, do you think you will offer any more of your week long courses that you offered a few weeks ago? I'd like to take a week of vacation next year to attend if you will be putting them on again.
I just showed this video to my welding class as they are distance learning. I gotta try that adjustable frequency stick thing! Also, dang curious how the balance control will affect it's behavior Two things with AC less arc blow and every farmer and their dog own an old AC buzz box. Thanks Bob!!
About two inches is a good length to stop. I used to work for a Boss who would eat your butt big time for running rods to short. He hated replacing stingers for welders who would burn the stinger up to keep from wasting a rod. When you think about it, he was right on in his thinking....
Ow, yes I know. The cheapest electrodes Jadran S form Elektrode Jesenice cost around 4€ for 1 kg, this is around 2$ for 1lb. For us welding sticks or electrodes are very expensive.
coatings re there for a reason. when the coating burns it creates an inert atmosphere around the weld. you have to have coatings to create a acceptable weld. spend the money.
I was loaned a MaxArc Mastiff gas engined welder after my inverter set went bang out on site. It was one of the nicest sets I've ever used and the arc sang a tune whilst I welded. The only info I could find on the set afterwards was a note someone had made on a forum stating that it had a polyphase alternator but quite how that fed out to the electrode holder I don't know.
@@choppergirl Wrong , you're obviously using the wrong batteries. Nothing outlasts Energizer. Which includes wall sockets, mainly because if the bill isn't paid, ehem, I mean hurricanes.
Great demonstration of welds on dirty or clean material and the effects of. I enjoy learning from your videos,plz explain why on flat piece to practice on it doesn't have a place to go, like when welding a joint of 2 pieces together then it has a place to go. Thanks

Ac is .707 the power of d.c. RMS root mean square
Some rods won't run on DC. AC also helps avoid arc blows

I haven’t welded in probably 15 years, took welding in HS 20yrs ago got so discouraged never really pursued it. (Short of a job making horse corrals). Now I’ve been bitten by the welding bug and watching a lot of these vids and Jody’s vids. Both have been so much more informative than I remember from HS.
This guy's a MAJOR improvement... now I'll subscribe .... I've been welding since the late 50's and my own shop for 25yrs. .... I never get enough.
I did my mechanic apprenticeship on a city workshop, next door in the same building was an old school blacksmith. He did all the fabricating/metal repairs etc for the machinery etc.
When laying down hardfacing on worn grader blades he would use 2 welders at the same time, strike arcs and lay the rods and holders (not the clamp one, but the ones you put the rod in and twist handle to lock) down, stand back and watch them both go. The object was to build back the worn cutting edges (early 1980's was cheaper to do this than replace blades every few weeks on the big graders)
Bob is my favorite to watch I've learned so much I thought I already knew... Never stop learning as a welder!!!
Bob is incredible, so helpful. He's got this Billy Bob Thornton style which is terrific.
Don't ever change any aspect of this program, it's the best out there. :) Thank you for your hard work.
Best decision I ever made was getting a powerarc welder and learning how to weld from youtube videos. It is such a great life skill to have. I only wish I had done it earlier in life.
love all your videos!!!! I've been slowly teaching myself by watching all your videos and enjoying every second of them. I so wish I was able to take one of your classes because I know with hands on experience with an instructor like you I would become one hell of a welder and have a blast doing it. Thank you so much for taking the time to share your knowledge with the world for people like me who rely on your videos to learn all the different techniques and knowledge needed to pressue a path of welding, while being entertained at the same time!
Thanks for the support, Corey. We will be doing more classes in different locations. We will announce them in the forum, so be sure to register over there. www.weld.com/welding-forum
Learning fundamentals of AC stick welding was important when I went to welding school. At that time AC stick rod welding equipment was the only thing a poor boy could afford. After you graduate welding school the first thing you do is buy yourself the best welder you can afford so that you can start making money out of your own shop or basement or where ever you can. Tuition for any good vocational welding school is expensive and you will need to pay those student loans. When you teach someone to weld with a buzz box you teach someone to feed themselves!
Believe that and respect it cause I did exactly that gotta get that money 💲
One time I had to make an emergency repair. I had some welding rods. I hooked up some car batteries and used jumper cables.
@@paulkurilecz4209DC! A pipe welder recently sent me a photo of his battery powered Fronius. Pretty amazing!
Bob,
I really enjoy your videos. I really like welding with 6010. I think it is the welding rod of real men.
Recently I saw some pictures of 6010 caps that were LACED.
That really impressed me. You being a long time welder may have learned that technique.
I for one with only two years of welding training and being 81 years old would be pleased to no end if you would show how that is done during one of your excellent videos.
Thank you
Sincerely,
Walter Luikey The oldest active Union Millwright Apprentice in the USA
Walter, congratulation!! Respect sir.
I remember all those laced 6010, 7010 caps too. Some were big old figure 8's. We have some outside our building on gas lines that were done probably back in the 60's. I doubt many would know what we're talking about.
When I was in welding school in the early 80's we started out with 1/8 6010's and 7018's. Everybody hated the 6010's because they like to stick. But they loved the 7018's because you could drag them and make a nice looking bead, and the slag came off so easy.
But our instructors said you like the 7018's now, but when you get more experience and become better welders, you will appreciate what the 6010 can do filling gaps and open roots.
Bob Moffatt In my 20s and I don't even know what I don't know. 😞 I just took welding as part of my carpentry apprenticeship and I am fascinated by how much science is a part of it. Anyway, I really hope you old guys record the things of the past in video or writing to be shared so the info isn't lost in my and later generations.
Walter Luikey dang! I feel like a high school kid! I'm 51 and just starting welding college man oh man you just made my day...
keep melting steel!
👏Much Respect Walter- Your Living Proof of the Saying, 'It's Never Too Late' - Keep the Sparks Flying Mate- Cheers 👍🍻🍺
Getting back into welding after 10+ years, I'd kill to apprentice under someone like Bob.
I have an ac/dc ark welder and no training. Wish I found your videos a long time ago. There is so much I don't know but I can come here and learn. Thank you very much! 👍
I been doing a lot more stick welding lately after a few months break doing mostly TIG. I notice that going back to stick (welding gate hinge brackets on steel fence pipes to keep the deer out of my Wife's garden) I was lightly holding the electrode about 3 inches back from the end with my non dominant hand and resting my forearm on the work piece. This allowed me to get much more comfortable and guide the end of the rod. Its hard to explain but my weld quality went way up while the rod was long.
I do alot of welding at work. I taught myself how to stick metal together. I just learned a lot that I was missing. Thank you!!!!
Well for the question about one of the advantages of using A/C for stick welding: It eliminates Arc blow because the current is alternating from E(-)/E(+) at the rate of whatever frequency (in Hertz) the machine is set to. Bob here can adjust it on that machine, but that’s a rare bird, and so is the machine 😁
Thank you
Oh my days never laughed so much for ages such a shame to read that Bob passed away these are old videos now truly brilliant to watch and learn from my name's Dean my partner's account is attached to Google and TH-cam
Bob is still around.
I have always been a mechanic or production assembler. That is until 3 weeks ago. I got a job with a great company looking for a welder. I talked a good game and did a few passes with .045 wire on a mig and got the job. I am doing great there because of your videos. I have watched most of your videos several times over and want to thank you for sharing your life of knowledge. I couldnt have made it without your instruction.
Mr. Moffatt you sir are one cool instructor. Funny but get a serious point across. Very enjoyable to watch your videos.
The first slag peel with the 7024 was great! I love when I get slag peel with 7018
"Today Bob will demonstrate the characteristics of different stick electrodes. He may even do some gas welding.."
But seriously - I've been welding for a long time, and these demonstration/ tutorials are great.Some stuff I just plain forgot, and some I never knew.
Love. Those. Bloopers.
This channel is excellent and you guys are doing a great job. I'm going to be teaching myself how to weld with an old Lincoln buzz box. You folks have been very informative. Thank you.
Just trying to wrap my head around all of the different rods I can use with my everlast welder and you've cleared it all up.
(Why AC?), I think historically there was also the issue of wanting to use AC-only transformer machines. At one time you needed a mass of rectifiers, or some amazing rotating dynamo. I wish people had kept more of these historic welding machines around! Really enjoying all these videos, and the 7024 one-piece slag was impressive. Good stuff!
I have recently gotten pretty addicted to watching your TH-cam channel. I have the opportunity to weld here and there at work just for the hell of it and I do so anytime I get a chance. I'm self-taught and I would say I can run a pretty nice bead for someone who has had zero teaching or anyone showing me what to do. I love the videos it is teaching a lot to someone like me who does not have someone to teach them but I have the opportunity to stick weld and I take it
Very nice video Bob. I love Your humor.
"Get to know Your rods" is the best advice. Using the different rods on the right polarity and in the right positions will make so much difference to the quality of the weld. The other one is. Practice, practice, practice, practice,........and then some more practice.
I will be runnning a lot of beads this weekend just because I love it and it keeps me in shape.
I'm just starting to learn welding and this has been the *best* instructional video I've seen yet!
That slag peel. So satisfying.
Kodizzie nice fist lol
I wish mine would peel like that. I’m still learning so it’s just betting it with a hammer for me.
@@FishFind3000 The first thing is setting and learning the machine also control heat with the angle and arç distance and speed so you can almost pick up a lead and already strung out in a power plant, they run almost strictly 7018 on mild and abrasive resistant steel, jalloy is hardened for abràsiveness from the coàl.Its painted green ón the edge bécause hardened steel is brittle, it's quenched at a làrger grain structure, it's harder steel and less flexible. You have to be able to identify it so someone doesn't make D rings or lift lugs out of it and get someone killed or injured.
If Bob bit it that would've made 2020 so much better! 🤣
Have you ever used the "torpedo" welders that the government used in the shipyards during WW2. It was an AC motor driven type that ran another armature for welding. Around my area there are literally hundreds of them left over from the war still in use. Very smooth arc and a joy to use. Lincoln also made one that looked like R2D2 that stood upright. and was a small simple welder that ran really nice also, It was a motor driven type just like the torpedo welder but much smaller.
Yes, the “silo welder.”
We had one of those old r2d2 Lincolns at a plant and it was well respected.
Lack of Arc Blow. AC because of it's switching action does not experience arc blow.
Good call. Correct!
I was thinking it was more like welding aluminum if the material it really dirty it would it would burn it out better at different frequencies
neat, i learned something new, great to go back to your previous video on 6013 arc blow and watch it happen
Bob taught me this yesterday!
aside from that wouldnt it also be a more stable arc and tighter profile and control?
Another great video. Keep in mind standard 7018 will not run on AC. You need 7018AC For that which is available at most places
Does the 7018ac on dc+ run the same as normal 7018 on dc+ ?
On the 3/32 7018, I loved when Bob said “Slag peel almost. It’s a beauty.”
Just started welding a little over a month ago, and I love it. Enjoying the videos Bob, we also watch some of your videos in class as well. Very helpful
No arc blow and you can weld around magnetic currents/ magnets without it affecting your weld pool
I learned how to weld on an old craftsman buzzbox when I was 8 yrs old been sticking stuff together ever since saved my ass more times than I can count I wouldn't be where I am without this skill. Good content Bob excellent video brought me back to the good old days tryin to burn whatever I had!!!
Thanks so much for the videos Bob. I bought the latest version of this AHP having never touched a tig or stick welder and only spending about three hours with a flux core machine. I’m having a blast learning and your videos are a great help to beginners like me.
Iono sir, but you are a great and cool welder and a great teacher. I'm getting into welding for hobby work. Watching all your videos surely helpful! Thanks for your time making these awesome videos! Forgot to say, watching you teaching about welding is very satisfying!
"Im on ac and it doesn't even sound like it"
*BUZZZZZZZZZZZZZZZZZZ*
I said the same thing I was like TF it doesn't sound like ac
He's right though, I bet its a square wave instead of a sine. Sounds different all right.
It sounds more like AC TIG, but probably quite different from say a buzz box or other power source that one might use for AC Stick welding
He cant hear it because the frequency is being recorded and Amplified with the camera microphone. Test this by grabbing your phone putting a Milwaukee or dewalt battery on a charger and hit record on your phone it should pic up a frequency that you cant hear without it....
Those that weld with various machines will know what was meant. The welder power supply is an inverter type not a traditional transformer /rectifier, so on ac welding a 60hz arc will sound quite different between the two types. Also the first welds done on ac were a higher frequency than usual, a sound usually found welding aluminium with tig.
And lastly check the table you're on LOL. Love your videos and content in my first year of welding at 39 years old and you guys are so influential and helpful with your content
Total newbie to welding. Never ever done it in my life until a month ago when I made 6 small spot welds (that are horrible I'm sure). Thanks for making this video explaining a bit about the rod numbers. I got a stick welder that I hope to learn a little bit so that I can fabricate small easy things. Looking forward to learning how to use it and to weld properly. Then I hope to advance to TIG so I can do a little bit of automotive welding for my hobby projects. I'm already fascinated by this.
Horrible spot weld or not, you tried, that's a start to improve on an build from.
Give yourself more credit, keep watching Mr. Moffat, don't matter if the video is not on stick welding, you are going to learn something that will apply to stick welding an don't try to learn all forms of welding at once, focus on what you are most interested in first, take your time an as Mr. Moffat says "Keep it simple.".
I'm at the learning point, no ppe or equipment because of the economic crisis, it's not a race.
2:40. I bought a Hone brand welder from Amazon, their arc welder. It was $84. I read reviews and a steam fitter used the welder to do large steel water pipes at work, commercially. He said it welded just as good as a Miller. So I bought one. And indeed, the arc is so smooth and the starting voltage is around 73 volts, no load. The welder produces such a smooth arc, it sounds like a steady hissing air, and the arc is rock solid, even if you turn the amps down 19 amps on the machine, with 240 volts input power, with 3/32 6013 rod. Read the reviews, but the new inverter DC welders, produce an extremely smooth arc, and it makes it a lot more enjoyable to weld. The inverter machines also are programmed with "arc force" to increase current if you dig the electrode in, so it's easier to maintain the proper weld bead, even if you accidentally get too close to the metal. For $84, everyone should learn stick welding.
i got a amico off ebay the 220 stick and lift tig did some 1/8 6013 as per bobs recommendations, brilliant!!! so smooth im afraid of welders typically, such a smooth arc and yes that arc force is AMAZING im no welder but my welds turned out absoluely aazing!! so true!!!
@@vickiesells8652I bought an Amico from a local guy (for a cheap plaything) knowing it will not run on 115, only on 240. Can you or anyone tell me how to fix it?
Hello from Slovakia , learned/-ing a lot from your vidjeos. Thanks
I live near by, in Sokovia
Your enthusiasm is infectious
Excellent video! Thank you. From what I understand most inverter welder's don't work well with 6010. Some of them have a specific setting to run 6010.
Right on man. Thanks for this. Y’all got good science vocalizing goin on, and I’m a HUGE fan of teaching ambidextrous welding. It should be an early skill path.
You never wanna be 30 minutes into a setup and realize y’all gotta come at it from a different angle cause you can’t use your other hand.
Our pleasure!
After reading it in comments, somebody said exactly what I thought - Arc blow.
Thanks for the video B.M.
We need more Bob vids . Please keep them coming.
i really enjoy watching Bob. great stuff Bob keep it coming.
I think this is my 3rd time watching this video, so much good info. Just ordered an ahp 201. Hope to get by the end of the month with all the craziness going on. Can’t wait to start glueing some metal together, thanks guys!
What a fantastic training video! I learned a semester worth on this one! Five star plus! And the welding part was great also ;).
If I had a teacher like Moffat I'd be a pro at about now. Been welding for more than a decade, still have so much to learn. Would sure appreciate more videos from Bob - keep 'em coming, please. Thank you.
Bob can you please do a video of running 11018M with a preheat and bend test
I’ll be watching this one over and over again. Thank you sir 🙏
Great video, always learn something new. It's one thing seeing how things are done, it's a totally different matter knowing why things are done that way.
I've started doing some practicing on my uphill game using some 3/32" 7018, runs beautifully
a nother great video Bob love your straight forward honest approach and your dry sense of humor you should do a blooper video I bet it wood be great please keep the videos coming
Check us out on IG and Facebook. Blooper stuff gets released there fairly regularly.
As a fix it guy with a Mig and Stick welder, This channel is very helpful
can we see a cut and etch of some 7014? we have a big 500 amp Lincoln ac idelarc and 7014 is our workhorse rod. We do a lot of heavy equipment repair and I've never had a failed repair. Just curious as to how much less penetration I get with 7014 as to 7018 or 6010 or even 6011.
Best regards Brett
I’ve had the same issue with 6011 as you did with 6010. I bought a tiny $170 80amp welder just for fun and it’s the first time I’ve welded since high school, so those two things may apply in my case, but I had a hard time keeping it from going out on me.
Great video! After seeing you change the frequency when ac welding i was wondering if you could change the ac balance.
Kevin Muehlbach Good thought.
I am probably too old to be a student but still learning. I am doing vertical welding using 6011 AC. I learn that I am using the wrong electrode. Perhaps a 7018 is indeed the electrode that l should be using at about 105 amp. I will give it a go tomorrow.
Hey, what about 7014? That's my personal favorite since it doesn't require an oven like 7018.
You are an amazingly skilful welder and a great teacher, thank you so much for sharing.
I would imagine with ac the advantage would be a balanced heat, not punching through, may keep heat balanced more on thinner stuff, and would also help with arc wander and arc blow.
The AWS and CWB numbering systems, wow, so helpful. Everyone has to master the numbering system, then you know what you can do best with it.
Bob is funny as hell. I'd love to be a student of his.
david lassell Come on.
Bob, do you think you will offer any more of your week long courses that you offered a few weeks ago? I'd like to take a week of vacation next year to attend if you will be putting them on again.
Ben Barnhart Yes, I plan to offer more throughout the year.
I just showed this video to my welding class as they are distance learning. I gotta try that adjustable frequency stick thing! Also, dang curious how the balance control will affect it's behavior Two things with AC less arc blow and every farmer and their dog own an old AC buzz box.
Thanks Bob!!
A/C reduces the chance of arc blow and keeps your work piece from magnetizing
I love all the information i get from your videos...all the tips .thank you Bob Moffat.
Where I live the electrodes are expencive and I use it all the way to the pure metal. I dont leave any coating on the electrode.
AirsoftSlo nnbbbb
fc
About two inches is a good length to stop. I used to work for a Boss who would eat your butt big time for running rods to short. He hated replacing stingers for welders who would burn the stinger up to keep from wasting a rod. When you think about it, he was right on in his thinking....
Ow, yes I know. The cheapest electrodes Jadran S form Elektrode Jesenice cost around 4€ for 1 kg, this is around 2$ for 1lb. For us welding sticks or electrodes are very expensive.
coatings re there for a reason. when the coating burns it creates an inert atmosphere around the weld. you have to have coatings to create a acceptable weld. spend the money.
Just started to learn SMAW last friday. Love your vids and thanks for the info Bob!
Bob: “I went to go check the machine and then there was an explosion.”
Me: 😂😂😂😂😂
Someone get the fume extractor 😂
kd k Lmfao😂
“ I feel better I tell you that I was kind of I had”😂😂😂
By far the best welding informational video i have seen on YT 👌
7:32 A: Because it makes a cool sound and impresses the ladies.
Godfrey Poon very good point as well LMAO
You're the best Sir,You make look so easy and not boring at all.Thanks Sir.
That's was a good lesson on rod types 👌🏼 good laugh at the end too! You guys rock🤘🏼
This guy is awesome, helps out so much, such a good teacher
"we are going to turn it up, I don't know what yet but we'll find it"-Bob
Sir, can you do what you did to 7024 to 6013? That,letting the rod run by itself?
i would use AC current when i play around magnets.
I was loaned a MaxArc Mastiff gas engined welder after my inverter set went bang out on site. It was one of the nicest sets I've ever used and the arc sang a tune whilst I welded. The only info I could find on the set afterwards was a note someone had made on a forum stating that it had a polyphase alternator but quite how that fed out to the electrode holder I don't know.
AC eliminates arc blow
Nope, it's because with AC you can run off a wall socket indefinitely, but with DC, you have to use Double or Triple A batteries which run down. :-P
@@choppergirl Wrong , you're obviously using the wrong batteries. Nothing outlasts Energizer. Which includes wall sockets, mainly because if the bill isn't paid, ehem, I mean hurricanes.
@@emeltea33 - Dunno, I have an illegal tap into the power grid, so there is no bill to not get paid.
@@choppergirl but Energizers keep going and going and going.
What is arc blow?
Great demonstration of welds on dirty or clean material and the effects of. I enjoy learning from your videos,plz explain why on flat piece to practice on it doesn't have a place to go, like when welding a joint of 2 pieces together then it has a place to go. Thanks
