  • Miller's 3 phase generator side of the Big Blue 500 & larger

    Can someone please explain the generator side of the Big Blue machines with respect to powering a 3 phase motor in an iron worker or plasma cutter?

    I have a '99 Thermal Arc Predator that has 480V three phase and it was purchased to power my Geka iron worker.

    Miller didn't offer any three phase engine drives then to the best of my knowledge either.
    When studying the literature on the BigBlue machines I see three phase but nothing as far a connectors, etc.
    Is the three phase for the welding circuitry only?

    Thanks,

    Tom

    50amps 3 phase 240v

    Nema 15-50r on the engine drive

      Thanks Ed,

      No 480VAC only 240...

        I'm pretty sure miller generators only run 230 volts whether it be single or 3 Phase, Cruizer would have more knowledge than I as to whether this could be changed.

        If you already have a generator set up to run it, why do you want to change.

          T-dyne Predator / t-bird and such are pure sine wave generators running at 460 3 phase. Had they been marketed as such, most would be around today. But they were marketed as welders, so most operators drove them into the ground.

          No the Big blues can't be set to 460, if thats what you are asking.

            That's what I was asking. I have a Predator and yes it's a 460VAC machine. The Italians do it a little different

              Cruizer, Thanks for that info, do you have to order them one way other the other or can someone like you change it back and forth.

                You can't buy a T-dyne pred/ T-bird or Wolfpack any more, so not sure which machine you mean.
