Looking for advice.
I made up a good deal of pie cuts. I'm going to start tacking everything in place, wipe it all down with acetone, and then start welding.
What I don't know is the whole back purge side of it. I know with stainless you've got to back purge or it'll give youi a terrible weld. I've ordered up an extra regulator for my Argon tank, but I'm curious on everyone's thoughts about how much pressure, how you made your purge exit, how long to let it saturate before welding, etc...
I was thinking of just the rubber tube for argon into tin foil to cover one end, then do the opposite end in tin foil with some holes poked through it. Not sure on flow or if gaps between non-welded pie cuts change anything.
