I am new to this Forum but I figured I might be able to get a good answer.
I was on a site yesterday and the plumber was having a hard time with this stainless steel pipelines, they were apparently leaking steam at certain times but when he showed up, nothing was leaking but at that point, he had already rented a Bobcat 250 Miller welder to try and weld his joints with some stainless sticks, tried running stick on a teflon & goop joint and to no surprise, did not succeed.
So He was talking to one of my co workers trying to sort out what to do and my co worker points at me and goes "he's good at stainless" True, I have a done a LOT of stainless but never done schedule 40 stainless pipe. I think it was some 1 1/2" and 1/2" and 2" joints, totaling 30 or so joints in all.
I have a Dynasty 200 that I think would be up for the challenge, I could not find the gas inlet hookup for the Bobcat 250 to TIG so I figured I can use it as a power source

I normally purge when I weld stainless pipe or at least try to but his plan is to make all the joints in the leaking area, socket joints and get them all TIG welded by me and one of his guys. Do I need to purge the line to do this? will be a lot of Argon.
it's a steam line for dry cleaning equipment nothing sanitary or food and it holds about 120 PSI.
Also, any advice would be appreciated, might not be doing it as its a plan B in case it starts leaking but I at least want to be prepared in case.
Thank you!
