Acceler8, I can relate! I'm 99% finished with all the rust repair welding on my 240. Been at it six months. The best value I've found on a mig welder "hands down" is the Century 140 Mig Welder available through Sears for $750. It has all the "goodies"-- spot & stitch welding timers, continuously variable heat and wire speed settings, dual range (0-90 & 90-140) and best of all it runs on 110v household. I've used and abused mine for the last six months and it has been a 100% reliable. Very easy to use. Funny thing is MAC tools sell the identical unit (except it says "MAC Tools" on it) for $1500. Go Figure. At $750 its a bargain! Happy Welding.
