Hi guys i have a small S.S job coming up its 12 gauge pipe welding thick flanges on 6-8-10 inch pipe? im thinking i will use 3/32 red tungsten. im guessing 1/8 wire? Any help is appreciated.

3/32 tungsten will be fine, 3/32" filler would work as well. I'm assume fillets since you mentioned the flanges. What is the fillet size spec? What's the use of the end product? What type of stainless?

3/32 red will be fine, unless you really plan to rock-n-roll at above 160A or so.

Personally, for heavy to light material, I'd choose 3/32 filler, as well, and do two passes, but that's a blind man's preference that allows me a clearer view of the root closure. 1/8" will do fine, especially if that's what you're comfortable with.
