Hello all!
I am a sculptor starting a project in stainless- It is an outdoor piece, three small tree forms that will act as sun shades for a poolside location.
Just bought a TA Prowave 185, after reading through lots of discussions, and it seems to work really well. I just ran my first bead after a few stutters and goofs- it looks pretty to me. There are a few places on the back side of the weld where crap seems to be forming- a very small scale, like one little growth on the back of a three inch bead. So ive read about providing a backing gas, obviously that is the way to prevent the oxides, but how important is it? will rust start here? How would you provide gas to a joint when the back is far inside a structure? How much gas to flow?
thanks for the feedback- Anthony Castronovo
