Well Scott, in the first place with 240 volts AC you don't have postive or negative; you have 2 hots, 1 neutral and a ground on the 4 pin plug. The 2 hots should be the 2 outside pins. You need to know a little more information but I think your plasma cutter would need the 2 hots and neutral. Check your schematics to be sure.
