I have a plasma cutter(DC output) that was designed to be used with an engine generator welder. The floating ground is brought back to the generator/welder. I don't have the generator & just want to run this on 220AC line voltage. The floating ground point can't be connected to an earth ground without tripping the GFI. Can I use something to take the place of the generators mass which is possibly an air ground? Please keep replys simple.
