    Question SS Exhaust pipe weld settings? (PowerTig 225LX)

    Happy holidays Everlast'ers,

    I've been trying to weld some stainless steel exhaust pipe (ebay brand) with 316L rod, but I think something is wrong with my settings, technique, or torch setup because all my welds look like crap :? . Can you guys please critique my weld with tips on how to make them better?

    Prep: Stainless Steel Brush on surfaces w/ acetone + paper towel cleaning.

    Tungsten: 2% lanthanated (3/32 size), sharpened to a point
    Amps: 40 (also tried pulsed @ 40/20)
    Gas: 100% Argon
    Torch: Air cooled Everlast
    Torch Flow: ~7-8 L/min
    Back Purge: ~2.2 L/min through the pipe
    Tungsten protruding distance from #7 EverLast cup = 4.32 mm
