First are you just welding stainless 304or 316? Second that wire your using is for welding stainless to carbon steal only . You want to use either 304 or316l wire. You'll get alittle discolor thats normal. But make sure your sheilding gas is comming out I prefer 30psi. The tungsten your using is okay for that operation. Hope this is helpful . I been welding stainless tig for the last 13 years. This should help you.
