jon, Marty,
Off subject question to help with my ignorance. PTAW is which, or is it both...[Plasma Tungsten Arc Welding] or [Plasma Transferred Arc Welding]?
jon was talking about powder so I was thinking it was Plasma Transferred Arc Welding, but with a brief search online I see PTAW called out as two methods and was wondering which is correct or is both correct.
