MIG Pak 10 operates on 115V AC, so you can plug it in just about anywhere. Yet it handles most jobs the home welder is likely to tackle from replacing floor and trunk pans, quarter panels, patch panels, and heavier gauge stock up to 1/4in. thick. For complete portability, the MIG Pak 10 can be converted to inner-shield welding so you can weld anywhere you have a power supply without the need for shielding gas.
