    Default XMT 300 CC CV Diagnosis Unusual Sounds Loud Click and Buzzing

    Newly acquired welder that welds as expected both with stick and wire feeder.

    When powering up there is a one time loud click. also, when the output contactor is moved into the ON position there a constant buzzing noise.

    When purchased the input was wired for 3 phase. I converted it to single phase and bypassed the red wire.

    Serial Number KD395855
