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.
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)✌️
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.
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!
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!
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.
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.
@@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 ..
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?
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?
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. :)
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.
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!!!

@@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 ;-)
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?
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
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?
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?

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
I’m trying to learn tig welding for automotive purposes tired of paying for it so I’m teaching myself hence this dumb question I’m gonna ask lol. What’s the purpose of purging I’ve watched a ton of videos where this isn’t even mentioned let alone done in the videos?
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.
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
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.
With reactive metals like stainless we pre-purge to surround the area in Argon before the arc strikes. It's a little safety measure against contaminants creeping in.
Tell us what videos you want to see on the channel here 👇
Would love to see some basics videos. Machine setup for different processes. Different settings and how they affect how the machine acts, etc.

is it going to crack or leak without the argon gas? or is it an ok but not perfect job?
Should the purge cfh be equal to the torch cfh?

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.
Why do we ensure the opposite side of the weld is shielded for pipe (this video), but not for other welds?
OK, so TIG-welding stainless tubes requires this procedure with gas on the inside?

How to do this commercially, if there is a company producing stainless systems on a large scale? (not "tailor made" for each customer).
Well, you would have robotic welders sealed in a room with pure argon atmosphere. There's no need to purge, because there is no air in the room.
