i was looking through some of my GM training stuff this weekend and came across a MIG/GMAW welding book. though some people might benifit from these settings. these are all for stainless steel, and i also have aluminum, nickel, magnesium and low carbon steel too if you want it. i'm going to try to copy the page and put it up somewhere this week, as well as some other things in the book that might be helpful.
