I use a 95/5 Argon/Oxygen mix for spray transfer and the increased amount of argon helps with the ionization potentials and the oxygens helps push the arc deeper into the root of joint and there is usually no splatter whatsoever if done correctly. Very nice video.
I dont know if your uk based or not but would you say a 93 percent argon mix with 5 percent co2 and the rest 02 would work on 26v? struggling to get true spray on my current gas set up on 83 percent argon
I agree. That would be an interesting comparison. There are some FCAW-G wires that have a higher diffusible hydrogen content, but it’s just something to consider when looking at wires. There are wires that hold an H4 classification which are readily available and commonly used. Then the mechanical properties can vary widely between wires also. The cool thing to do would be to match the properties as closely as possible and then compare in flat/horizontal as well as out of position. It’s hard to beat a quality FCAW-G wire when it comes to vertical or overhead welding, but on a super thick flat fillet weld over clean material, spray transfer with metal core or solid wire could potentially be more effective. I would love to put those theories to the test though!
If it's gas shielded fluxcore it's gonna have better ductility especially if you use straight co2 spray transfer hardwire while it penetrates really deep in the root it dosnt do as well with impact or shock as a 71t1 or t8 t6 wires
For all watching remember that spray transfer is the only type of GMAW process that is pre approved by code. Short Circuit welding requires a qualified procedure and welder.
I finally got a bottle of 90/10 to try spray and pulse on my millermatic 255 after owning it for 6 months lol, this is the first time I’ve tried pulse or spray, spray is so fucking slick! It’s HOT AS HELL THOUGH, you’re gonna need one of those silver mig backhand insulators! I like it, I’ll start using it more, also I had a hard time finding this info, for anyone who has a 255 and isn’t knowledgeable on spray, try 28.0v/425wfs to get you started in spray, u can use 90/10 gas for mild steel and regulator at 35-40cfh. Took me an hour to find that info so hopefully you see this lol
Last week of September he should be back. He's been posting on FB and appears to be enjoying football, his camera, and life. Let's give him space to finish up what he needs to.
Thanks for covering this topic! I am not so sure if the "rule" Spray (@higher voltage) versus Short Circuit (@lower voltage) => deeper penetration serves as a solid guideline. As far as I know, short circuit welds (e.g.
Stefan Hertweck you are correct. WFS controls the amperage (heat) Voltage is just the electromotive force driving it and controls bead width. The purpose of the experiment was to show that short circuit should not be ran on thick materials. The two modes of transfer are not equal in amperage. Short circuit works great on open roots because of the fact that it has low penetration and excessive penetration is not ideal on open roots. That’s why the root is ran with short circuit for the root, and the fill passes and cap are usually done with a different mode of metal transfer (such as globular or spray) or a different process such as SMAW or FCAW.
Stefan Hertweck thanks for the calculations. I haven’t messed around with them since I did my fundamentals of AC/DC final exam, I did a brain dump right after the test 😂
@@GodslilRedneck23 Hello Jason, no problem. The basics are very simple. As it relates to power, it is calculated Voltage x Current (in simple terms). With Voltage or Current alone you can't weld, it is the product (multiplication) that matters, that is P = U x I [unit is VA or Watt]. Now, time matters. If you let the current run for only a short period of time, let's say a second or even less, you consume just "a little bit" of energy i.e., E(nergy) = P(ower) x t(ime) [unit is Wattseconds or Watthours]. However, if you let the current run for a long period of time, you consume more energy (more Wattseconds) and it will make a big difference in your energy bill :). Now, before the "electrical engineers" chime in ... yes, there are more details to this topic like wave form (voltage/current wave form) and the "type" of resultant power/load (active/reactive/apparent power in combination with resistance/impedance). But in general, knowing that: P = U x I => higher means you run "hotter" and E = P x t => longer means you are "heating up" the material is helpful when you are setting up your welding machine. Hello welders, let me know if you find any errors in my simple explanation or if missed something, besides details of the dark side of electronics :)
this is so hard to explane to "welders" who dont understand welding and think thwy know everything that just cause its fast and pretty that wire welding with solied wire is not the way to go. i could show them by doing this test and theyd blame my skills or show them your video and they tell me how you dont know what your doing and they do. they would also never do the test themselves cause then people would see there "welding" skill. thanks so much for putting out tjis type of content.
we had 12 failing a simular test on school. because the did not clean/flat sharpened the bar before welding. so never weld a T joint or simular with a rounden side :)
.035 FCAW 14 volt 90 amp 230ipm 2-3 inches of stickout good for spot welding 22 gauge sheet metal, .035 FCAW 28 volt 140 amp 280ipm can weld the broken crankshaft out of the truck. One wire that can do everything at the flip of a switch... 035 flux core.
Klay Chesham hopefully our paths will cross Travis and Kevin spoke very highly of you when I was with them in Houston. I’ve also enjoyed your videos on TH-cam.
rik999 I wanted to do that but we didn’t have a gauge. The purpose of the test though is to show the lack of fusion, not the amount of force to break it. To demonstrate force or load, a tensile pull would be more appropriate. We showed that test in the Stringers VS. Weave video.
I've been wondering what spray actually was n the difference to regular mig so basically if I understood correctly short circuit is lower voltage n wire speed to match n spray is anything over a certain voltage with wire speed to match with the proper gas mix
Ben Miller yes but with short circuit the wire shorts out to melt the wire, whereas with spray, the electrode is literally sprayed off the end of the wire and tiny droplets fall into the puddle.
@@GodslilRedneck23 ohhhhhhh that's why the arc looks so much bigger with spray right? Cuz it's jumping farther from the work so the puddle is created n melted wire is sprayed into it. You know if you keep teaching me all this welding when all I have is a harbor freight flux core welder you're gonna have to give me a welder so I can put all that theoretical knowledge to use lol
Ben Miller you know harbor freight has that Omni pro 220 multi process machine that isn’t that expensive. It does mig, tig and stick. I learned a lot using that machine and there videos. A side note on that machine though. The auto settings are a little low, I find myself turning up the heat a lot from there factory settings.
WaylonCarl once you understand what each setting does, you’ll learn to dial it in no problem and you won’t use the auto set features anymore. Hopefully we can help you out on that venture.
Jason Becker you have been doing an outstanding job of helping me learn and improve already, I have no doubt it will continue. It’s a slow process without schooling but you guys are doing an outstanding job!
Can you do a macro etch on a cross section to better show the comparison of penetration? Also is there a formal standard for the definition of spray transfer vs short circuit? Is it defined in D1.1?
TD Engineering yes, a macro tech can be done but we wanted a larger sample to represent the whole weld not just a small cross section of one area. The standard definitions are available in the AWS A3.0 Standard Terms and Definitions book. It’s not defined in D1.1 but it is stated in D1.1 that it had to be qualified to be used whereas SMAW, FCAW, and GMAW Spray are prequalified.
What’s your thought on short circuit for weld buildup on plate .480” thick. Mostly in the 3g or 4g position. Weld buildup is for abraded areas on a carbon steel tank. Or would you use Spray or Globular. Thanks
Thomas Elliott .480 is thicker than 5/16” so in wouldn’t use short circuit. Since it’s in 3G you can’t run Spray or Globular. I would run pulse spray or use a different process.
I know this is an old video but getting in to welding these are all great! I have a question: How do you handle dust from grinding in your shop? Uncontrolled it gets EVERYWHERE including in the air.
There are vacuum network systems you can buy that can be set close by above the project at hand. I don't know how much they cost but I imagine that someone could create such a system by modifying a shop vac ;)
When I had to take an unofficial weld test on plate like this. The welder was already set and I wasn't allowed to change it. But I digest, he bent the t joints the opposite way you did, is there a reason for that?
Now if you were to use short circuit and position the joint so that it would be at about a 60 degree angle and do a vertical up. Would that make a stronger joint? I only have a short circuit mig and when I need a more structurally sound joint I like to go up. Good or not?
Depends on joint prep, material thickness, and technique. If you are making little triangles as you work your way up and can watch the weld dig into the corner of the joint, it should be fine.
You still wouldn’t get adequate penetration on thicker material with short circuit. That’s why AWS doesn’t allow any GMAW short circuit to be prequalified.
spray transfer is way better for base mettals that are thicker than 5/16" because it wleds it better togetehr due to the penetration/ deapth defussions right?
@@GodslilRedneck23 run it everyday an work welding together heavy equipment like angle blades and excavator buckets. Like to see their prospective on it
It would be short circuit, you need higher amperage and higher amounts of argon for spray, you likely have a 25/75 co2/argon mix. Most MIG welding is short circuit so if you don't know it's likely that your best set up for that.
so it's just in the settings? (and a little in the gas) just hotter settings and more wire for spray? sorry for the stupid questions, I just never did get the difference. What about sound? bacon?
Can all MIG machines above a certain amp range do spray transfer; or do you have to purchase a machine with that specific capability in mind? Thank you for the video.
I can _just_ get to spray with my Lincoln 180. Barely, and I have to go down to .025 to get there. The machine was really not designed for it. 200+ amps would be better.
The amperage threshold is just one aspect. A lot of lower-wnd machines have limited voltage capability when you increase the voltage, so its not just wfs/amperage. The machine has to have enough balls to let you increase the voltage as well. You need to look at the volt-amp curve of your machine.
Now I get the difference between short circuit and spray but can anyone explain to me the difference between spray and spray pulse? Are the settings different?
VERY different. Any GMAW welder capable of getting up over 25V can do spray. Pulse spray is a welder specific feature designed to give the benefits of spray with reduced heat input.
Is anyone else surprised how easily both broke? I know he had quite a bit of leverage but I still would have thought the welds would have been stronger than that. Kind of makes me second guess some of the things I have built.
Thanks. Yes I understand that but still I guess intuitively I would have thought a roughly 6” long good weld on 3/8” material would have been stronger even if only welded on one side and pulled in the weak direction.
@@txdoodlebug I think you're underestimating the mechanical advantage here, it was enough to bend the plate had the weld not failed and if your base metal is bending you have other issues besides the strength of your welds. However it was a good reminder to think about which direction the force will be applied on parts you're welding.
I would like too know more about the Everlast 275 mts - features and cost when does Everlast plan on put it on the web site and start selling them, Is it a duel voltage welder, is it A/C, D/C, do all fuctions run at 275 amp's, the display look a little small hard too read, how hard is the menu to operate, how's the duty cycle, is it worth it for the extra 25 amp's, how does it compare too the mts 252 sti. I've been putting off buying the 252 sti too try and find out more about the mts 275 lightning
The Lightning MTS is an updated version of the 252. It is still a 250 amp machine. It has some updated features and the new digital interface. We will be releasing it for sale in early 2020 for around $3,800 - $4,000.
No if you can do it then go for it. For 304 use a 95%Ar/2%O2. Or a TriMix gas. Use a 308L filler wire as well. Keep inter pass temp below 350*F on multi pass welds.
Hi. I watch your videos and they are very helpful, because I am in the beginning of welding cariere . My question is can you make maybe one video with some cheaper welding machine? Becouse in my country and that is Montenegro, I can only dream for ESAB REBEL or any kind of ESAB welding machine. Also there are no where to look or to buy: KEMPY , FRONIUS , EVERLAST ..... and so on. We only have VARSTROJ and TELWIN , that we can afford and that we can buy to begin welding. So can you make maybe one video with VARSTROJ or TELWIN ? Pretty PLEASE 😊
Personally I stray away from either yes spray does penetrate deep but its alot more harder more brittle if I'm welding anything structural I'm going with a ductile material like 7018 or dual shield or T8 wires just not found of hardwire period I've had short circuit as well as spray fail usually cracking on spray and lack of fusion on short circuit
James Holbrook in short circuit the wire physically hits the base metal/puddle about 20-200 times a second. In spray tiny droplets of weld wire melt off and fall into the puddle. The wire never touches it.
@@GodslilRedneck23 ok how is this accomplished ? At some point there has to be some contact in order to start the arc ? Or am I missing something about this process??
@@madcapmagician6018 initially there is contact between the wire and the base metal, but when you have an argon rich mixture (usually 90/10 or 92/8 Ar/CO2), the wfs passes a certain amperage threshold, and if the voltage is high enough, the arc simply stays "on" from that point on. So as the wire goes through it, it literally liquefies and is propelled to the base metals, hence liquid droplets of filler wire are "sprayed".
What's the definition of Spray Transfer and what's the definition of Short Circuit? I don't know what is being done differently just from looking at the video. Thanks.
Short circuit is literally that. The wire is shorting out to complete the electrical circuit to make the wire melt. Spray transfer is using the higher voltage to cause the current to "jump" between the wire and the joint. This also causes the wire to melt in advance and spray into the weld joint. This is why the wire speed is so much higher, it needs to keep up to how fast it's melting.
In short circuit the wire is literally shorting _in_ the weld pool and melting there. That's what's causing that frying sound that you don't get with spray. With Spray, the wire is melted to almost a mist and carried to the pool across an arc. Wire speeds are really high too. I can't get there at anything less than 30v and 400 ipm on my Lincoln. Spray also requires a minimum of 80% Ar so it doesn't work with C25. There are a couple of good videos here on spray/globular/short circuit mig. Definitely worth watching.
Globular is similar in that respect, but the current isn't hot enough to achieve a spray. You can literally see drips of molten metal coming off the end of the wire. with spray, all you really see is the wire taper to a needle point.
If short circuit is not fusing, then what IS it doing? Cause it's obviously doing something. It took a lot of mechanical advantage to break that weld. Is it adhesion? Magnetic attraction? Van der Waal's forces?
This is for Mr. Bob. Can you do a video showing how to wrap/tie in corners. Corners such as mitred square tubing. Going from inside fillet to outside fillet then back around to inside. As elaborate as you can. I’m using 1/8” mild steel. Millermatic 130xp. 120v. Voltage knob setting 4 wire speed on bacon sound. Flux core Gasless .035”
Ok with all due respect Tru ss with the same settings.... Because I have welded thicker plates with ss mig... And have not had failures . Could that be because of the machine being used? Could u please try again with an older mig v the new machines and see what happens? Or how about stick v spray transfer .
@@GodslilRedneck23 I don't understand. How can a person thumbs down a direct comparison of spray to short circuit? I know what _I'm_ not going to do with 3/8 plate anymore.
biased result for the short circuit. you cannot go into spray transfer with 75/25 gas. so you could go all the way up to 27 volts just like the spray transfer and Achieve nearly similar penetration. also for the 22 volts you had way low wire speed which will also give you low penetration. along with your technique notorious for lack of penetration and not allowable on structural welds. should have been around 22 volts and 350 to 375 wire speed. or if you wanted a true non bias test run both at 25 volts and the corresponding wire speed to the transfer mode.
Jason Becker you literally said that the other day no matter what you crank the voltage to with 75/25 gas you will not achieve a spray arc. which I can confirm when I weld every day I love to crank the voltage to at least 25 and if you check out the weld table in my Lincoln Power MIG 256 it will confirm that as well. you can also achieve a spray arc around 24 volts with the right gas. the transfer mode is dependent on the gas and voltage but both could be at the same voltage with different transfer modes. case closed biased result. I like how you reply when I call you out but you don't reply when I wanted you to do a video on safety.
Jason Becker when you were talking to that guy in the comments about I believe how he got leukemia and Parkinson's and was dying because of all the things he was exposed to from welding. it's a very overlooked thing in the industry and I'm literally talking to dudes everyday about safety while they sit there in a galvanized plume of smoke not even keeping their head out of it let alone wearing a respirator. honestly could be a five-part series if you wanted to go in-depth with it, covering all of the processes and different types of safety equipment that exist, that no one even knows about. do you know how long it took me to get my supplier to give me a proper welding respirator with the right cartridges, literally months and he was scratching his head so I had to do the research myself and give him a part number which he still couldn't find. Honeywell makes a pretty good one that is inexpensive and goes on your back. its one of the affordable for the average guy non forced-air respirators.
Matt B I do remember that. We try to build safety into every episode. As far as fume safety we did a couple fume extraction videos a little while ago. I am currently looking into doing other videos to demonstrate fume safety. It’s a long process to get the videos planned and get the resources needed to get them done. Sorry if I didn’t answer your question directly. I try to get to everyone that comments in the videos, but I also help out on Facebook and Instagram as well.

You should do a video on 1/16 metal core
Eric Brugnoli that’s a biggin, we’ll add it to the list.
@@GodslilRedneck23 run it everyday an work welding together heavy equipment like angle blades and excavator buckets. Like to see their prospective on it
I have an Eastwood175 mig. How do I know if it's short circuit or spray? This was a great video, and thanks.
It would be short circuit, you need higher amperage and higher amounts of argon for spray, you likely have a 25/75 co2/argon mix. Most MIG welding is short circuit so if you don't know it's likely that your best set up for that.
Should I use short circuit or spray on a truck frame? That is about 316?
so it's just in the settings? (and a little in the gas) just hotter settings and more wire for spray? sorry for the stupid questions, I just never did get the difference. What about sound? bacon?
Also try this using pulse spray. I find a pulse spray at 25.5V and 400ipm runs really well on our robots
adejong95 pulse runs great on robots. Have you done any rapid arc or rapid x?
Jason Becker we have Miller power sources so rapid x and rapid arc aren’t options. AccuPulse is great though
adejong95 haven’t had a chance to try that yet.
Dangit, I want a Bang now.
Why so high of gas flow on the spray transfer?
That fume extractor sucking up all your gas?
Would .045 wire give you the penetration using short circuit?
Seth Thomas not really. It’s the mode of metal transfer that has the restriction not the filler metal or diameter.
Makes sense. Thanks for the info
Seth Thomas no problem man, thanks for watching.
Sir where welders use only co2 gas in mig?? I'm beginer and have lot of questions,, or mix gas is ok for universal welds,
What about for spatter? Gas wise? We run out machines hot! 26 to 29 W 10g but 75 25 gas. What do you suggest?
Argoshield 8C 30 CFM , 26-28 volts, 550-620 IPM
Can all MIG machines above a certain amp range do spray transfer; or do you have to purchase a machine with that specific capability in mind? Thank you for the video.
If you can get to around 200 amps you can get to spray transfer. Depending on materials used can run from aprox 180 to 350 amps in spray.
I can _just_ get to spray with my Lincoln 180. Barely, and I have to go down to .025 to get there. The machine was really not designed for it. 200+ amps would be better.
The amperage threshold is just one aspect. A lot of lower-wnd machines have limited voltage capability when you increase the voltage, so its not just wfs/amperage. The machine has to have enough balls to let you increase the voltage as well. You need to look at the volt-amp curve of your machine.
@@zod-engineering-welding Okay, thank you
With 100%co2 spray tranfer can be done?
Now I get the difference between short circuit and spray but can anyone explain to me the difference between spray and spray pulse? Are the settings different?
VERY different. Any GMAW welder capable of getting up over 25V can do spray. Pulse spray is a welder specific feature designed to give the benefits of spray with reduced heat input.
Is anyone else surprised how easily both broke? I know he had quite a bit of leverage but I still would have thought the welds would have been stronger than that. Kind of makes me second guess some of the things I have built.
Drilldo it’s designed to fail that’s why we only welded it on one side. The backside of the plate has no reinforcement so it’s an area of weakness.
Thanks. Yes I understand that but still I guess intuitively I would have thought a roughly 6” long good weld on 3/8” material would have been stronger even if only welded on one side and pulled in the weak direction.
@@txdoodlebug I think you're underestimating the mechanical advantage here, it was enough to bend the plate had the weld not failed and if your base metal is bending you have other issues besides the strength of your welds. However it was a good reminder to think about which direction the force will be applied on parts you're welding.
I would like too know more about the Everlast 275 mts - features and cost when does Everlast plan on put it on the web site and start selling them, Is it a duel voltage welder, is it A/C, D/C, do all fuctions run at 275 amp's, the display look a little small hard too read, how hard is the menu to operate, how's the duty cycle, is it worth it for the extra 25 amp's, how does it compare too the mts 252 sti. I've been putting off buying the 252 sti too try and find out more about the mts 275 lightning
The Lightning MTS is an updated version of the 252. It is still a 250 amp machine. It has some updated features and the new digital interface. We will be releasing it for sale in early 2020 for around $3,800 - $4,000.
do the same test with the tig
Any dangers to spraying 10 ga. 304 or mild steel when you are traveling really fast?
No if you can do it then go for it. For 304 use a 95%Ar/2%O2. Or a TriMix gas. Use a 308L filler wire as well. Keep inter pass temp below 350*F on multi pass welds.
98/2 and 92/8 are my only choices.
@@hodgepodgeenginerd1258 O2 or CO2?
Do you know when this machine will be available?
Everlast is telling us early 2020.
“...cool down to at least room temperature” do you expect that if you wait long enough, it will cool to below room temperature? Just wondering.
Sure. Just raise the room's temperature.
Hi. I watch your
videos and
they are very helpful, because I am in the beginning of welding
cariere
. My question is
can
you make maybe one video with some cheaper welding machine?
Becouse
in my country and that is Montenegro, I can only dream for
ESAB
REBEL or any kind of
ESAB
welding machine.
Also
there are
no
where to look or to buy:
KEMPY
,
FRONIUS
,
EVERLAST
..... and so on. We only have
VARSTROJ
and
TELWIN
, that we can afford and that we can buy to begin welding. So can you make maybe one video with
VARSTROJ
or
TELWIN
? Pretty PLEASE
😊
Personally I stray away from either yes spray does penetrate deep but its alot more harder more brittle if I'm welding anything structural I'm going with a ductile material like 7018 or dual shield or T8 wires just not found of hardwire period I've had short circuit as well as spray fail usually cracking on spray and lack of fusion on short circuit
What is spray how is it not short circuit
James Holbrook in short circuit the wire physically hits the base metal/puddle about 20-200 times a second. In spray tiny droplets of weld wire melt off and fall into the puddle. The wire never touches it.
@@GodslilRedneck23 ok how is this accomplished ? At some point there has to be some contact in order to start the arc ? Or am I missing something about this process??
@@madcapmagician6018 initially there is contact between the wire and the base metal, but when you have an argon rich mixture (usually 90/10 or 92/8 Ar/CO2), the wfs passes a certain amperage threshold, and if the voltage is high enough, the arc simply stays "on" from that point on. So as the wire goes through it, it literally liquefies and is propelled to the base metals, hence liquid droplets of filler wire are "sprayed".
@@zod-engineering-welding thank for the information, I had heard about this process, just never used it. 👍👍
So basically it maintains an arc but what is different with the machine and wire just a higher
that tack on the side made it harder to break
mohammed troy yeah, I caught that after almost flipped the table over 😂
But made it fun to watch him try 😂
What's the definition of Spray Transfer and what's the definition of Short Circuit? I don't know what is being done differently just from looking at the video. Thanks.
Short circuit is literally that. The wire is shorting out to complete the electrical circuit to make the wire melt. Spray transfer is using the higher voltage to cause the current to "jump" between the wire and the joint. This also causes the wire to melt in advance and spray into the weld joint. This is why the wire speed is so much higher, it needs to keep up to how fast it's melting.
In short circuit the wire is literally shorting _in_ the weld pool and melting there. That's what's causing that frying sound that you don't get with spray. With Spray, the wire is melted to almost a mist and carried to the pool across an arc. Wire speeds are really high too. I can't get there at anything less than 30v and 400 ipm on my Lincoln. Spray also requires a minimum of 80% Ar so it doesn't work with C25. There are a couple of good videos here on spray/globular/short circuit mig. Definitely worth watching.
Globular is similar in that respect, but the current isn't hot enough to achieve a spray. You can literally see drips of molten metal coming off the end of the wire. with spray, all you really see is the wire taper to a needle point.
This brings back the days of chucke2009, but a more high performance test aha
but you can easily get undercut with spray, so watch out for that.
Try it at 800ipm and about 26-28 volts. You can absolutely crank .035 to ridiculous speeds if you need to.
I ran 32V and 725 ipm for cap pass. Each pass blended nearly seamlessly.
yup! thats what i ran my settings at roughly when i was welding tank heads on lol, big ole slick 1" wide cap or more
Fuck yeah! I love cranking the wire up and just flying. But I'm usually 27-29V and 500+IPM
When I was practicing for my 1st year Government exam practical portion 1G (GMAW, FCAW, SMAW, OxyAcetylene Welding and cutting
RIPIPIP that poor welding table. Like Starship Enterprise, taking it to warp 9.
If short circuit is not fusing, then what IS it doing? Cause it's obviously doing something. It took a lot of mechanical advantage to break that weld. Is it adhesion? Magnetic attraction? Van der Waal's forces?
balisticsquirel it fused into the side wall but not into the actual joint. It works great for materials less than 5/16”.
I have only tried mig welding 1 time and the sad part is I have a Lincoln procore 125 mig welder
This is for Mr. Bob.
Can you do a video showing how to wrap/tie in corners. Corners such as mitred square tubing. Going from inside fillet to outside fillet then back around to inside. As elaborate as you can. I’m using 1/8” mild steel. Millermatic 130xp. 120v. Voltage knob setting 4 wire speed on bacon sound. Flux core Gasless .035”
Ok with all due respect Tru ss with the same settings.... Because I have welded thicker plates with ss mig... And have not had failures . Could that be because of the machine being used? Could u please try again with an older mig v the new machines and see what happens? Or how about stick v spray transfer .
New vs Old wouldn't have an effect on whether the mode penetrates. Maybe a slight change in setting to achieve short circuit or spray, but that's it.
Someone thumbs-downed? WTF?
Minja Leoppky right? What’s up with that?
Some people like the democrats too!
@@GodslilRedneck23 I don't understand. How can a person thumbs down a direct comparison of spray to short circuit? I know what _I'm_ not going to do with 3/8 plate anymore.
1st
biased result for the short circuit. you cannot go into spray transfer with 75/25 gas. so you could go all the way up to 27 volts just like the spray transfer and Achieve nearly similar penetration. also for the 22 volts you had way low wire speed which will also give you low penetration. along with your technique notorious for lack of penetration and not allowable on structural welds. should have been around 22 volts and 350 to 375 wire speed. or if you wanted a true non bias test run both at 25 volts and the corresponding wire speed to the transfer mode.
Matt B 25 volts wouldn’t be considered short circuit.
Jason Becker you literally said that the other day no matter what you crank the voltage to with 75/25 gas you will not achieve a spray arc. which I can confirm when I weld every day I love to crank the voltage to at least 25 and if you check out the weld table in my Lincoln Power MIG 256 it will confirm that as well. you can also achieve a spray arc around 24 volts with the right gas. the transfer mode is dependent on the gas and voltage but both could be at the same voltage with different transfer modes. case closed biased result. I like how you reply when I call you out but you don't reply when I wanted you to do a video on safety.
Matt B where did you ask for a video on Safety?
Jason Becker when you were talking to that guy in the comments about I believe how he got leukemia and Parkinson's and was dying because of all the things he was exposed to from welding. it's a very overlooked thing in the industry and I'm literally talking to dudes everyday about safety while they sit there in a galvanized plume of smoke not even keeping their head out of it let alone wearing a respirator. honestly could be a five-part series if you wanted to go in-depth with it, covering all of the processes and different types of safety equipment that exist, that no one even knows about. do you know how long it took me to get my supplier to give me a proper welding respirator with the right cartridges, literally months and he was scratching his head so I had to do the research myself and give him a part number which he still couldn't find. Honeywell makes a pretty good one that is inexpensive and goes on your back. its one of the affordable for the average guy non forced-air respirators.
Matt B I do remember that. We try to build safety into every episode. As far as fume safety we did a couple fume extraction videos a little while ago. I am currently looking into doing other videos to demonstrate fume safety. It’s a long process to get the videos planned and get the resources needed to get them done. Sorry if I didn’t answer your question directly. I try to get to everyone that comments in the videos, but I also help out on Facebook and Instagram as well.
No offense but the the videos have been a lil week since bob left
