how do u guys set up for sheilding the back side of your staineless welds? thanks!!

For pipe, i usually tape off the ends and make a small hole for the tubeing from the tank to fit in.
For flat pieces, seems like a cabinet is required.

Thats what i thought i would have to do and i do alot of thin sheets and not many with a root gap and ive been have issues sometimes, now is pure argon good enough? or is a mix say 75% argon 25% helium better or worse?

pure argon is the way to go. 75/25 argon/ co2 is only for mig, never for tig and never for purging.
