Great video! This is condensed and perfect for the person having a bit of trouble or the person who just bought that first mig welder and wants to learn from the best. Bob we have a lot of respect for you and this great free service you are providing to the world of welding. You are Mr. Welder because you specialize in all welding from what I have seen. No one is all around better than you. Thanks for all the behind the scenes work you have to put in to make a 25 minute video. Thanks also to your camera man.
Thanks for the kind words and support.
I only offer the respect you have earned!
Only person on TH-cam that is at the same level is Jody Collier. I really hope he is one of the collaborations mentioned
sidewaysdanny The thought of that collaboration almost makes me start shaking with joy. I would love to have camera duty on that video. I desire to keep growing as a welder I thirst for more knowledge and improvement to my skill set. No matter who you are you could always be a better version of you. I went to Hobart 20 year ago and have welded every since but I have learned things from watching both these men. I hope to someday reach their level. I just keep watching and trying new techniques. It takes a lot of hard work to become a better welder but when your welds really start to shine the satisfaction is great. The stuff I weld is just going to go in a boiler and get ugly fast but it still matters to me what the customers see when the new parts are delivered.
You come off as the Mr. Rogers of welding...... "Won't you all weld with me today?" Yes, I'm an old welder and Yes, I truly respected Mr. Rogers and Yes Bob.... I truly respect you and your videos. I just bought a Legacy 200S Gmaw/Smaw machine and this video helps because there's NO chart included. GBYAY!! Kenny in Vegas
Hahahaha. I'm still chuckling about the Mr. .. Bob Moffatt thing. :)
balisticsquirel Me too!
Almost forgot there, didn’t you?
Mel Gross Nope, you didn't catch it.
Ha, I bet you did forget, and you’re covering it up!
Mel Gross How much you got to bet?
Bob's videos were always some of the best online... the newer ones push the quality up to 11. Excellent arc shots. Crisp audio. And guaranteed to teach something. Also, sometimes, we get a bonus: Bob's Bloopers/Outtakes!
Vax 4200 I'm working on my blooper game.
Bob Moffatt Will be watching.
Mr......Bob Moffat....LMAFO.... AND.THANK GOD !!!!! This channel has improved 10000000 fold since Bob started doing the videos ! Thank you Weld.com
Thank you for all of your great content. As a welder by trade I must say, short arc MIG is one of my favorite forms of welding.
Great video bob!, saying a hearty hello from Canada 🇨🇦 I’m currently a 1st year welder and your info and wisdom helps me out all the time!
Mr. Moffat I think yours is one of the best channels for educating welders and future welders. I have been welding for nearly 30 years and I still learn new things all the time. some times you need a reminder also. Great source of information here and I appreciate your efforts.
I'd meaning is a good teacher don't lose this guy he has good teachings
Bob I'd a good teacher and he has good humor and makes welding more exciting with his humor and teaching has great video with the darkening lens on cameras viewing in from a distance we didn't have that in welding school
I'm 99% a TIG guy, but found this video interesting and educational. Watched the entire video and learned... Bloopers were funny at the end too. Thanks for the upload.
You are a great teacher helping me a lot
I am an old welder too and yes you have my respect. Great video!
Richard Valcourt Thanks for the feedback and support.
he encourage me to subscribe, i was like " hell yeah i want to subscribe to this amazing channel " then i move my mouse, and realize i was already a subs ^^ nice job guys, continue you are making a great job
I always learn something from your videos Bob. Even if I don't use the weld processes you're showing in a particular video, I always get something out of them. Keep up the great work and I will keep watching. Thanks!
I liked the last workpiece. Uphill Mig, stunning weld bead!
You almost said Mr. Mig, didn't you? Lol, too funny. Great channel, even with Wyatt!
That's exactly what I thought as well! Haha!
There was a moment of hesitation. Who am I... ?
Bob's the man. I love his videos. I've always wondered about the different ways my everlast mig welder can weld. Now I finally know all of the ins and outs.
i am working on moving to the welding side of my job and i find these videos very helpful, thank you!
Bob moffatt, awesome teacher
Thanks Bob, my TH-cam welding teacher!
Love your videos! Been a carpenter and all around remodeled most of my working life and now been wanting to do welding for hobbies and love every bit of information.
I love watching your videos here from morristown TN, I come from a supply industry and this helps me better understand some of my customers processes
Excellent work as all ways.
I like fact that you screwed up because I learnt something from it.
The fact that you blew through and give the reason why.
Not gonna lie...Spit my coke out when you said' "Mr....Bob Moffat"..... Priceless...
Hope it didn't come out your nose!!
I like this guy. Learning a bunch of stuff to use with my everlast welder.
Yes, it is educational. Also very helpful. Thank you.
Niiice! Hog Back position in a self unloader.
Education? That's very knowledgeable. And that's why I subscribe. More Mr. Moffatt, more!!!!😁😁😁😁😁
Bob, I've learned so much from your videos, my MIG, TIG and Stick welds are worlds away from where they were when I started watching your videos. I do a lot of work on very thin sheet metal, vehicle floors and bodies. Do you have any techniques for very thin materials with Mig and/or Tig Welding? I'm mostly working in the 22-18 guage range. Thanks again for the great videos.
Oh man.....!!!! This guy is such a character.......!!!!!
Thanks much always enjoy and learn from your videos👌
Got a new job and they run Fronius pulse mig on aluminum. Unbelievable machines
cleveland mortician if you ever get the chance HTP Pro Pulse is Pulse mig Aluminum too it’s an awesome machine made by Stel I’ve dont a few videos on it
You are the bob Ross of welding
Thanks for the video Bob.My Esab EM 215 ic definitely runs cold on recommend settings compared to my Millers.For 14 gauge I am running 18.5 volts and 240ipm for most of what I do.I am always running this welder at 1 volt hotter than recommend.My ESAB Rebel amazes me on how smooth and spatter free it welds when properly set up.
Which one is better?
Love your style. All we can do is learn from you.
Love this idea. I really liked the black and white shots at the begining. GMAW is the easiest way to make bad fusion look good.
I subscribed back then, and you left Bob, you just freaking left the scene. I hope you're doing well.
LOVE this type of teaching videos! Im newer to the welding scene and ive mainly been into tig more than anything but i also have a mig welder so ive always wondered what globular and spray transfer was compared to short circuit, so this will be a series i will DEFINITELY watch. Ah hell i watch all the videos lol but i will be looking out for these videos for sure!
Excellent stuff Bob. I have the EM and have suspected I've been running it too hot. Thanks for the correct settings ;-)
Our Pleasure. Thanks for the support.
Excellent video, Thanks for taking the time to share your knowledge.
Hey man awesome stuff. Thanks for the info. Appreciate you giving us all this knowledge, we know you don't have to do this. You know all the rest of that. I really enjoy the way you teach man. You get straight to the point but you're not in a hurry. You give us just enough tid bits of correlating info and then you're back on subject. Thanks again for all you do. From Texas with love, keep we moovin.
I appreciate everything you share Bob I could use more of your pipeline skills to get faster. Love the stuff you did with South coast welding school.
I gotta get one of those rebel welders. They're awesome
Thanks Mr. Bob , that is awesome mig welding lesson
I'm a beginner with mig welding ...and i would like to see a video about bad tig welding / mistake in mig welding and how to correct it....if it is possible....
Great intro and great video! One request could you do a live shot of your classroom intro to the day before going out to the shop? Maybe some of the book work that the students have to go through before all the Hands-On training. Thank you Ed K Cleveland Ohio
Great video Bob,I look forward every week to watching your videos.I'd like to see you do a video on stick welding dirty rusty steel where you can't get a grinder in the area you need to weld(I use to work in a gravel bank for a time).
Kudos to camera man! Keeping up with that travel speed on the 14 gauge 😬👌🏼
Niall Menzies He was whining the whole way.
Thanks Bob Videos look Even better now!!!
this man knows his onions.... great content
Learning so much from these videos, many thanks!
Fantastic so much excellent information, thank you subscribed for life 😊
Love your videos! Learn a lot from them.
Good tips for litle girls and garage welding. Try that on shipyard in the watertank chamber, where u weld in all position posible with mirror welding and upside down with your head down :) and stuff :P
Awesome video. Always a student. Man you’re steady
Really liked your video. Easy to follow and I learned a lot. Thanks
Thank you. I'm learning that I have more to learn!
LOL! "I'm Mr..." Balisticsquirel is correct, I'm still laughing!
Fantastic camera work
Awesome 👌 as I'm going to do some 1/4 in x3 in tube this weekend 😀
Great channel.
Great demonstration Bob!
Love the format, the audio, the arc shots, from the first second to the last, great video. Having watch the video once, I'm trying to understand what voltage effects. Wire speed, got it, but volts, well. My brain has had a hard life so I need to watch the video a few more times or look it up in my Lincoln Foundation Procedure Handbook Of Arc Welding.
Sparky The Welder Voltage is arc length and makes to pool wet.
I guess trying to pull the electrode back from the work piece to extend the arc would be an exercise in futility. Thanks Bob. Much appreciate your wisdom.
Bob I love watching you're videos xD I hope you keep hosting them.
Ark city rocks!
If I can learn to lay down that bead half as nice at 64 yrs old with my first mig, I'll be happy 😁
Good video! Would help us across the pond to add metric conversions like you used to on some older videos.
now then now then now then...yet another good one Bob.... ;-))
Another great video!
Around 14:55 I see you moving the torch forward and back a bit, adding more heat and wire. Could you please talk a bit about what you are looking for, how we could know how much to do that, or is that another video? I would like to develop the correct habits while learning.
Nice video. Learned some stuff here. Great content. Btw, those are some great arc shots.
thank you so much
little more everyday, I'm learning
Great video, great teacher, thank you
Thanks, great video!!!!!
As usual a great video. Also audio and video much better!
Great video👌Reeeally!! Educational Mr: Bob M. 😃
We run way less co2 over here and a touch of o2 works well
Mr. greens boat tanks and aluminium welding You can get that kind of blend here too, there are commonly available tri-mixes (95-5-5, I think). But 75/25 is what everyone can get even at the local hardware. There are also a fair number still running pure CO2 because of the increased penetration.
Bob I own several welders. haven't used them in several years due to back surgery. my welders control amperage and wire speed. I feel like ripvanwinkle, what's with the voltage vs wirespeed? This feels like when I woke up one day, and degrees Celsius was the game.
Excellent audio and video!
very very informative the science too good welding
Ron White fan! Haha love it! ....Uuuuuuse it! ....COOp'n!
Great content thanks Mr Bob 😄
Very good video. Very good demo.
Yay, Bob is back :D
Please, please, PLEASE use the EM215ic in some of these videos! 🤞🏼
We've used it many times in the past. We haven't tested this, so don't take our word for it, but I would think that the settings on the EMP would be the same as the settings on the EM.
Thanks for your teaching. Gives me something to work towards! But I have a total-newbie question: are you running at 120 V or 240V? I just bought a shiny green unlimited 200 and have it plugged in to a 120V 20 amp circuit. Do I use the settings you provide (i.e., 17.5/200)? Or, since I'm still learning can I reduce the voltage and feed speed? Thanks particularly for your comments on cleaning the metal. Didn't realize it would make such a difference.
Would you expect an inverter and transformer machine to give the same sound in short circuit mode ?
Yes
Geez, what was my name again? :D You do a great job, Mr. Welder!
That video quality tho!!!
Great videos, keep up the good work.
Thank you Bob.... I learn....I burn....I earn!
Bob, I have a question. I don't have a fancy MIG with a bunch of bells, whistles, digital readout, and all that stuff. Just a little Lincoln 180 with a couple of knobs, and a chart in the door. I am a self/older guys taught in the shop TIG welder that mainly welds nasty old Harley cast aluminum, and steel for tools, frame repair, and so on. This MIG thing is new to me, and until I started watching these videos, I never knew any terms for different kind of MIG welding, much less it existed.
So here is my question: do you do something different for short circuit with the machine itself, or is it just the approach, distance of the nozzle, and so on?
I really appreciate your videos. Maybe I will come visit you some time. I'm just down here in OKC.
Thanks!
David
What is the Very Best Tig Welder for the Money . Thank You
Somewhat unrelated to the actual welding... Where did you get the round supports that you use on your table? Did you make those, or are they something you can buy?
Priceless intro, SOOO glad you didn't say Mr. Mig.... You are Mr. WELDER, that other guy was a bore and I'll leave it at that. Thanks for sharing your knowledge.
clean sounded nice and stable while the 2nd one, dirty, sounded sorta like it was stuttering a bit.
Welcome to Weld.com, I'm Mr.... Shtick. Well, we already have that annoying Mr Tig, we may as well have the always entertaining Mr Shtick!
I Like it!
I use miller deltafab .045, 220v 3 phase, 90/10 running multi-pass on 1/4 and above on semi axles. Painted much of the time so we run it very hot to burn off the paint.
What do you think the best settings would be?
Hey Bob, from what I’ve read using 75/25 gas tends to give a bit cleaner weld than pure CO2 making it very popular. But I have also read that pure CO2 with short circuit method gives a bit deeper penetration and same settings & a slightly cheaper gas, Is this true? Also does straight CO2 burn through mill scale or slightly rusty metal better, or would you choose flux core wire for the very best penetration, and for burning through contamination using the short circuit method of metal transfer? Thanks for your great videos Bob. 😎👍
We stay with the 92/8 gas all the time. Mainly for our spray passes but we use it on our short circuit root passes also. Is there really a good reason why we should not use that and use 75/25 for the roots? i have never had a problem with the 92/8 for the SC process, was just wondering if there is something to watch out for.
