  • Xmt 304 no weld output. "Again"

    I received this xmt 304 from a friend. It had no weld output and help 7. I replaced igbt's and d1 and 2 diodes. It welded great for a couple days then nothing. It now shows 7 volts but no help code.

        I checked output diodes d1 and d2. both 200k oms either direction. I am trying to test igbt's again and having some difficulty. I maybe should take board off and then test them?

          Make sure your resistors on the power board OHM out. But oyu should have a fault code showing
