:> I shudder everytime I hear "harmless" used in conjunction with welding. :>
: Have you ever read the MSDS for Stainless Steel filler wire? : I have. : It basically says, do not grind this metal into fine dust and snort it : like cocaine.
: There are no hazzards from TIG welding stainless steel, other than : those posed by the arc process itself.
: You are under considerably greater danger when grinding or polishing it. : Just wear a respirator.
: I am a welding instructor. : I HAVE to read the MSDS whether I want to or not.
: Caution is one thing, blind panic is another.
Amen!
