All you guys are leaving out a proper power source, welders suck juice like crazy and trying to weld while browning out is very frustrating and non productive. I have a 200amp service just for my machines. Although I have been scolded that 100 amps would have been plenty. Trust me on this, 50 amps are barely usable and will heat up your entire system in a bad way with continuous use. Even my Miller 110v wire welder will not function properly with a 25 foot 14 gauge extension cord. Match up the machine you procure with the power source you can provide.
