3 or 4 wire connections to razer weld 45?

1

I am wiring up my garage for my welders, compressor and plasma table. I need to know do I need 3 or 4 wires for my plasma cutter. I have recieved everything but the cutter so I do not have it to be able to find out. I am not sure how much longer it will be before I get it and don’t want to wait to finish the wiring job. Any help with this is appreciated!!!

Welcome

You need 3 wires, 2 hots and a ground. I would install a Nema 6-50R with #6 wire and a 50 amp breaker. That way you will have all the power you need for the welders as well as almost any plasma cutter you would need.
