    Esab Migmaster 250 power correction

    Good evening all. I've been reading offline for a bit and there seems to be much for me to learn here.
    Looking at a post about power factor correction on transformer welders and wonder how do I know if I have it in mine or not.
    This ESAB is my newest machine and I also have a Dialarc HF and a 330 A/B and Hobart RC300 (3 phase)
    All help appreciated.

    If you can't tell from the serial or model number, you can usually tell from the electrical specifications plate.If your welder has PFC, the idle current draw will be pretty high, and somewhat close to your current draw at the rated output amps. If you do not have PFC, typically the idle current will be very low.
