That's what I'd do as well if I were in your shoes. But I'm in my shoes at least for today. And up here the cheapest Nema 14-50 plug is 50 CAD before tax at the home deep. I think I mentioned it (my outrage) in another electical thread. The matching receptacle is 10 CAD what gives!?

Anyways, I found it unreasonable because I can get 6-3 Romex for a buck a foot. If prices weren't that insane, I'd do everything 14-50 too.

Question: Is this going to be an extension cord or will it be hardwired to the welder?
