This is a used welder collected from a large fabrication business that upgraded all their machines to newer models. Unit powers on, and was tested at 208V 3 Phase, which is how it is currently configured. I do not have a wire feed unit to fully test the welder. If you would like to bring a compatible wire feeder to test it, prior to purchasing, just let me know. Available for local pick up. I am willing to load it on a pallet and onto a truck with a forklift, if the Seller would like to arrange for shipping of this welder.
