  • Millermatic 250X low voltage to wire drive motor- Need Help

    I recently purchased a used Millermatic 250X in need of repair. The wire drive motor is not working. I disconnected the leads to the motor and tested the voltage going to the motor when the trigger is depressed. The voltage to the motor goes from 1V DC to around 20V DC as I turn the wire speed up, which seems correct according to logic and everything I have read.
    I put about 16V DC direct into the motor from a battery and the motor doesn't spin. Everything moves freely by hand.
    Is there another way to test the motor to see if it is shot. I believe it is.
    I would really appreciate any help.
    Thanks
