I have some nascar friends and they all seem to use a mig procss to weld but
they are welding mild steel. I dont think those guys are using any
chome-moly.
I have a torch in my shop and two other welders - a Miller syncrowave 250
which is for tig but can do stick too-- although I never use it for that .
It has square wave technology and welds aluminum and cm really well on ac
and dc respectivley. My other welder is an older welder from Linde that is a
needle arc welder . Different looking weld pool, great penetration, internal
radiator for the torch and goes all the way down to 5 amps dc
consistently.750 pounds though. Bought from a NASA auction-- cool stuff but
I am always using my miller and poking hole in my mask with the hot filler
rod. It has really taken a beating over the years.
By the way I always heat treat my chrome moly stuff after. Some do , some
dont . I do.

Bruce, you might ask around and see what they use to weld together those
NASCAR chassis with.
Jim in Palmdale where it actually SNOWED last night, well technically it was
snow but it was only 1/4 inch thick
