I've got a Sears Craftsman 35-230 Arc Welder for sale. 240 volt input. I've had it for 15 years and before that it was my fathers, he bought it new and never used it. I've used it quite a bit but now have a Miller Bobcat so it's just taking up space. It's always best to size welder circuits and wiring based on the input current requirements of the welder. For example, 240-volt, 40- to 50-input amp welders will require a 50-amp circuit breaker and 6-gauge wiring. Welders operating at 30 to 40 input amps require a 40-amp breaker and 8-gauge wire.
