    Chrome-moly should be set up the same as normal steel. DCen, 100% Argon, 12-15Cfh, 120 Amps and less for the thickness you are talking about. Make sure fit up is tight and carry a short arc length to keep from overheating the joint. Chrome-moly is more heat sensative than mild steel. Pick your filler by application. See some of the previous question about 4130 or Chrome-moly. Most racecar application work nice with an ER80S-D2 filler.
