run MIG off 5000 watt portable generator?
I've got a 130 amp 120 volt MIG welder that I'd like to run off a portable generator so I can take it out in the field (I'm at a small farm). The generator is a homeowner type Coleman 5000 watt generator, one of the cheaper units with a 10 horse flathead motor. Supposedly, the max output of this generator should be around 40 amps, which should be plenty to power the MIG, which takes up to 25 amps max input. Is there any reason not to try this? Could I damage the MIG if something goes wrong with the current output of this rather cheaply made generator?
