Want plasma cutter, but no power hookup

What are the listed power requirements of the cutter? I used to routinely extend a Lincoln 200A buzzbox, and later a Century AC/DC welder, with no10 to a dryer plug. This was on a 40A circuit. You can get away from this just fine because the wiring won't be in a wall, or conduit, where it can overheat.

Sounds to me from what you describe the dryer/ basement window is as good as you'll get for a quick/ temporary hookup.
