  • Hypertherm 380 to 220V

    So since I went through the hassle of adding a 220V line for my Miller 175, I figured I may as well run my Hypertherm 380 off of 220V as well. I know there's the switch on the back and I can easily buy a plug, but if I cut off the current plug, can someone tell me which wire goes where on the new plug? Please. I'm trying to learn this stuff - I did put in the new breaker needed for the 220V line, but it's taking me awhile to learn this stuff.

    Just make sure the green ground wire goes to the ground on your 230 plug.It's the center tap on a 50 amp range plug.The other two wires can go to ether of the two remaining taps.

      Thanks Scott.

      Got it done and the house didn't even burn down.

      .... of course I must be doing something wrong 'cause I couldn't cut through the 1/4" plate. .

      Gotta keep working on this. Thanks for the help.

        Hypertherm has a very good customer service help line, call them with your problem, perhaps the voltage switch-over inside the rear of the plasma is in the wrong position. 1/4" should be OK with a 380.
