I have an Everlast Super200P. It uses 1-phase 240V input power. (2 live 240VAC conductors, and one equipment grounding conductor.)

I was wondering if anyone knows if I can wire an adapter to operate this welding machine off of a 3-phase 240V receptacle?

The 3-phase receptacle I would like to run my welder off of is a NEMA-L15-20R

I only need to TIG weld some .040" stainless using this. (Probably won't be drawing a large amount of current.)

Thanks!
