i would like to upgrade from my sa-200 to a nice diesel drive welder, lincoln or a miller pipe-pro (no big 40 or 50's though) trying to set up another rig truck for lil brother also. also has anyone heard of a place in lousiana that converts sa-200 to a diesel engine? i got a couple that the motors are toast in and figure it would be cool as heck...any help would be greatly appreciated
