While this extension cord is rated @ 20A @50 feet, it is borderline when welding at the maximum heat setting. I'd prefer a #10 gauge cord. You could try it, and if you didn't like it, buy an adapter [20A to 15A] for the plug end and use it for an ordinary extension cord.

The cord plugs into a 20A 120V outlet only. This type of outlet MUST have #12-2 with ground all the way from the main panel to the outlet. ---- Be safe
