- Today Chris McQuay, AKA @unobtainiumwelding, is going to show us how to weld stainless steel exhaust tube, on the cheap! If you just bought your new Everlast welder, it's only a matter of time before your buddies are going to be banging down your door to weld their exhaust system. You don't need an expensive purge setup to weld stainless steel tube. All you need is an extra argon line and some aluminum foil. So if you want to learn how to weld stainless steel from one of the best exhaust builders on instagram, here's your chance.

Would love to see some basics videos. Machine setup for different processes. Different settings and how they affect how the machine acts, etc.
Just got my Lightning 275. Let's see some aluminum vids.
Some .063 aluminum tube

To take the back purge a step further, I'd suggest sealing the end plugs tight with ductape (you could even dispense with the balled up foil and just use ductape to close off the ends) then put a pinhole in the end opposite the gas inlet side and adjust the inlet gas flow for a steady gentle outward flow at the outlet side, which would insure a steady gentle outflow at the weld gap as well. If you use the balled up foil for a plug you could still wedge a small piece of 3/16" brake tubing etc in the opposite end, the idea is to have a controlled and verifiable end-to-end gas flow, not just random leakage at both plugs, the inlet side should be completely sealed and the outlet side should have controlled outflow, insuring the center weld zone is covered with gas. Give it a couple minutes of flow time to purge, then weld while flow is steady.
Exactly! And to improve your improvement as the Argon is heavier than air you want to put the pinholes mostly on the upper side of the ductape. 😁 (It's just my thing, I don't know actually if it's technically the best way to do it)✌️
Your Over thinking it lol
There are so many hack welding videos on this site that it's super refreshing to see one like this where it's done right and also demonstrates what happens when it's done wrong.
I bought one of what might have been one of your earliest multi-function machines (TIG/Stick/Plasma) about a dozen or more years ago! Still have it - still love it. :)
Great clear to the point lesson with excellent demo. Thank you
Super simple and informative! Would like to see more demos like this in the future! Weldgreen!
Stay tuned! We've got new vids every Thursday
I bought an Everlast 210EXT maybe a month ago and I love it thanks guys. Up next will be a water cooler. I'm glad to see you're putting out new content maybe soon I'll be good enough to do some videos for you.
Thanks for supporting Everlast 🙏 Get that hood time in and it's always a possibility.
Awesome video! Thanks Unobtainium & Everlast 🤘
“Weld mean weld green” I have always wanted an Everlast welder, would look awesome in my garage!
Weld tube sent me. Looks vary informitive, ready to learn something new. And I did. Foil ingenious. Thank you
I bought the Everlast 256i.... nice machine, good service from techs.
very nice vid, explaining and showing why.
Weld mean weld green. My everlast welder was stolen and I’m out of work from the covid pandemic. Hoping to save enough from side work to buy another. Everlast last welder are the best there is period. This company has helped me feed my family for years!
Really great video. Thank you so much for making it!
I've had pretty good luck with *Solar Flux* type B for stainless exhaust tubing. You dissolve a small amount of the powder in methanol and paint it on the back side in lieu of Argon backup right before welding (it can fall off when dry). Only mix what you need. The residue is glassy and really hard to remove, so this is not a great choice for hygienic work like food plumbing or intake runners, but it's the cat's meow for exhaust work where a bit of debris is OK. I think it saves a lot of hassle and some money. Besides, it was a classified technology in WW-II.
Does it prevent the concaving of welds or no?
@@JACK-jm7bo + No, but it mostly handles sugaring on the back side where shielding gas is not present. The glassy residue is hard to remove so it works well in exhausts but not so much for food plumbing ..
We did this when welding 36” pipe in the field where you would go broke purging the 500’ pipe run
That’s the first time I ever seen anyone use aluminum foil to purge, not hating or anything, just first time ever seeing it be done like that, I learned using tape, one side completely closed for the hose, and the other side little pin holes so it flows out, and keep tape where the welds are going to be done. Great job!
That’s crazy. A lot of people have done this for years
Awesome vid. Love my everlast 185!!
I own Wheat State welding LLC. I have been using an Everlast I mig 205, 60 amp plasma cutter and a 250 amp AC DC TIG machine from Everlast for The last 5 years the only failure I've had was a low voltage power supply in the MIG welder that tech support told me was a common problem because the fans fail and take out the power supply. I sent them information from my own troubleshooting and they sent me a new power supply that arrived within a couple of days. Everything came with instructions and worked out wonderfully. after 5 years of hard use I had to clean and adjust the points on the tig machine yesterday. That was a super simple job and now I have an HF arc start again. these two things are literally the only problem I've had from all three of these machines using them daily for The last 5 years. Once a year I open up all three machines and blow them out thoroughly. But that is the only maintenance I do to themI have been blown away by the quality and performance of the Everlast machines and we'll put them up against a Lincoln or Miller any day of the week. I love my Everlast equipment and would suggest taking a close look at it for anybody who's trying to find get equipment on a decent budget for their shop.
Nice work, explains a lot ,thanks man
Great information here!
Very nice. Been a fan of you for a while now.
Weld mean weld green. My husband would absolutely LOVE this.
Just watched weld tubes video on the giveaway. Those guys are get definitely awesome your guys unit look awesome. I'm a new welder maybe 12 hours in. but seen a recent video video of purging the inside of the tube with gas. Finnagins garage. If you don't load the tube with gas on an engines exhaust or turbo set up it will pull the crystals that form on the back of the welds and could ruin a turbo. Great video showing both with and with out gas.
Can’t wait to try out this beast 🤞🏽🤞🏽🤞🏽
Great video, hoping to build myself an exhaust system over the winter - thanks for the info dude
Any time! make sure to tag us when you build it.
"Reynolds Caps" Should be a trade name. Saved the bacon many times! Nice video!
Weld mean weld green. I'm almost done with welding school. This would help out soooo much
Weld mean weld green!
Great vid. Keep it up!
Fairly short and to the point. Good comparison.
Thanks so much for your video
Wow, finally a Everlast video! I really enjoy my water cooled 210EXT ! How about some vids on 18ga or 16ga lap and fillet welds - Aluminum ; with and without pulse And the settings you use (d). Tacking 18ga Aluminum would be helpful also. Thanks for the Video Chris.
Added to the list
Weld mean weld green! I've heard alot of great things about everlast!
Weld mean weld green!!! Love me some Everlast!
Weld mean weld green! Love it
Weld mean, weld green! Trying to get a start on my welding career and fix some body work on my truck.
Awesome video so informative
@unobtainiumwelding is one of the best in the business when it comes to stainless exhaust 🔥
Everlast Welders I’m a welding student and definitely will be watching more of your videos :) thanks for uploading.
i had no idea that everlast had there own RUclips channel awesome tons of great videos
It's been static for years. We just relaunched. We're going to have new videos every Thursday with members from the welding community hosting every episode.
@@everlastgenerator If I was to get a good MTS welder that'd work great for my mobile rig I'd gladly do plenty of review videos on how well it works during real world mobile rig repairs and fabrication work ;-)
great information
EVERLAST 🍀
It would be advantageous to move the tin foil plugs in closer to the area being welded so as to reduce purge time and make a more perfect inert atmosphere inside the pipe.
Good job sharing
Hey brotha love the videos! Just curious (Now this maybe an overtly dumb question since I'm basically a layman in terms of welding knowledge) but I'm a very diy guy whose instinct is to always get something done on the spot without buying the proper and necessary tools for the job so my question is, what if I don't have an extra argon tank laying around? Is there any other easily obtainable gas' that I can use as a replacement?
For other people on SI units: a CFH is cubic feet per hour. 1 CFH is approximately 470 cc/min.
If you want the purge to come out better you need to diffuse it somehow. The way that a lot of us achieve this in the field is by folding a piece of masking tape about four times and then taping over the purge hose end to act as a splitter for the argon to hit.
I’ve made close to probably 1000 X-ray quality stainless welds using this method. Also when you’re welding in position if you don’t have enough purge it will make it more difficult to get penetration on the bottom of the joint
This reminds me of silver soldering in HVAC&R. Purging nitrogen inside the copper pipe at the proper rate so you don't blow out your silver solder and making pin holes. The purge in silver soldering removes the oxidation of the braze and the copper and doesn't allow carbon build-up. Basically the same thing I believe, only now we're welding. the next step above silver soldering, and we want a strong weld so this adds to the process. YAY - Argon!!!
Man I would love an Everlast welder

Would love to learn this skills
Nice. Thanks 👍👍
Weld mean, weld green
Really need this to start my career off on the right foot
Clearly worth it.

"Weld mean weld green" I have one of your plasma cutters. Would like to see a vid about nozzle types and sizes.
I know it’s all argon, but can flow from the purge blowing through the seam disrupt the gas coverage from your cup? Do you need to use a higher CFH through your cup when you’re welding pipe with a purge than you would typically use with the same size cup welding plate?
Extremely happy I watched this. Thank you. So, picture this. Building a curve with multiple angles. So if building a curve and everything is butting up lovely. Once tacked up. Will it be just as good with the purge? You had two open ends and you had one joint. I'm talking two open ends and let's say 6 or 7 joints. Is this the same set up?
Weld mean, weld green. 🔥
Weld mean, weld green
Perfect for the shop
Weld mean weld green! 🤘
“Weld mean weld green” been needing a welder would love it to be free lol
I'm gonna learn on a budget mild & aluminized steel build, will have thick stainless collector flanges... what filler and what else changes?
Weld mean, weld green. 🤘🏼🤘🏼🤘🏼
I saw the title and thumbnail and said out loud: "oh hell yeah"
Great example and explanation!
The legend
What wall thickness is recommended for exhaust and turbo manifold?
What shielding gas would be best for welding sch 10 304 ss to mild steel? Plan on making turbo manifold for my cruze since the factory one's nothing but issue's & expensive to replace for something so small!
TIA
can you use single argon bottle with a dual flow valve? one too the welder the other to purge. thanks
Weld mean, weld green! 👍🏻
weld mean weld green... Good vid!
How come you add filler rod? I’ve always done stainless tubing with straight purge no filler autogenous sanitary tubing mainly
is it going to crack or leak without the argon gas? or is it an ok but not perfect job?
“Weld mean weld green” would love a dedicated tig machine!
what is the thickness of the exhaust tubing? And what volts/amps did you use?
thx
Muito bom o vídeo
Do we have to purge when welding slip joints?
Have you guys tried using solarflux B before?
It's only exhaust tube so does it really matter?
I get your point though for other projects
Should the purge cfh be equal to the torch cfh?
Weld mean weld green 🤘🏻
The Myth the Man the Legend, awesome Chris.
Why do we ensure the opposite side of the weld is shielded for pipe (this video), but not for other welds?
I like your videos , not many do ss steel thin
Weld Mean Weld Green ... Looking to replace an antique Miller Syncrowave 300 and a VERY Old Tri Arc 180 MIG
I bought my Everlast TIG machine to start modifying and making roll cages from DOM mild steel. I hadn’t even considered trying to purge inside. My results have been good but rarely some porosity. Would purge be worth it?
Purge isnt needed on DOM or chromoly.
Mild steel is not a reactive metal, like stainless, and therefore doesn't require back purging.
Weld mean weld green.
👍👍👍👍
This machine is a beast #weldmeanweldgreen it's the only machine that gets in between
It might night looks as nice but wouldn’t it be stronger wirhout the gas?
Love to see 316 marine rail tubing. 7/8”, 1”
Sir itu hose masuk dalam pipe. Itu argon bukan ? So itu macane las tig tidak ada argon kah ?🤝🇮🇩my from indonesia
OK, so TIG-welding stainless tubes requires this procedure with gas on the inside?
Can I weld with Rahin but back purge with c25?
Forget about Happy ever after this “weld mean weld green” machine is the “happy everlaster” the only machine that gets in between!!
weld mean weld green ✊🏽
Hola, qué maquina usaste?
Saludos amigo.
This was done with a PowerTIG 255EXT
Esto se hizo con un PowerTIG 255EXT
Could you please explain (show) the difference beween the LIGHTNINGMTS 225 and the POWERMTS 221SI.
The Lightning 225 replaced the 221. The 221 is no longer being manufactured and is no longer available for purchase.
Everlast Welders thank you for your quick awnser. I would like to purchase a 221 in Europe. Are the specs of the 225 simular to the 221? What has changed?
Check: Lightning MTS 225
Second Generation Success.
The industry was changed forever by the predecessor of the Lightning MTS 225. The PowerMTS 221STi, was the first compact MIG, AC/DC TIG, and Stick unit to come to market. It was innovative and reliable full of many functions that the industry still hasn’t matched to date. The blood line continues strong in the new Lightning series. The new Lightning MTS 225 has the same features as the old PowerMTS 221STi, but has a few new ones of its own, with the syner- gic Power Set function and fully digital LCD display. A new wave form for has been added as well for AC use in the form of a Soft Square wave.
Will it be Sanitary if I don't purge and just weld it on both sides?
Always purge, keep clean. Use ss brush/wheel, wipe down with acetone.
Would it matter to have that oxidization on the inside of an exporst pipe?
Big no no
I have a question, when I finish welding stainless steel it will make a small hole at the end of the weld ?how to fix it?
Add filler
How do you tack without rod and without special functions on the welder?
Aurelian Munteanu you do whats called fusing. You need the metals to be side by side with no gap between them. Otherwise you need filler wire. If you have no gap, you just put a small amount of heat into the metal, right in between the two pieces youre joining, and let the heat fuse them together. Don’t put too much heat or you will blow a hole. Just enough that the metals melt at the point of your tungsten and want to join together. Then take off the heat as soon as you see those two puddles join. A foot pedal is really good for this, but easily done with a button on a torch and the right settings. Best to start low amps than high ones
Weld mean, weld green!!
Love it !
