Stainless Steel Mig Welding From http://www.brazing.com/techguide/pro.../stainless.asp :
" FCAW - Flux Cored Arc Welding-Mig Welding - Flux is contained within the electrode. It provides shielding, deoxidization & arc stabilization. Additional shielding may be added. A smoke suction nozzle around the gun or fume hood aids in reduction of smoke & fumes. Aufhauser flux cored stainless steel wire is formulated to provide all position welding & smooth, stable arc action."
Also, try: http://www.brazing.com/products/Weld...red_stainless/
There's a lot of good info a each site.

My local welding shop also suggested trigas for stainless. I just welded up a bunch this weekend, and they all turned out very nice and smooth, no porosity or obvious defects that I could see.
