    Why do the net fuses blow during startup with my Kemppi Master 1400 Welding System?
    • D
      Daniel QuinnAug 6, 2025
      The net fuses might be blowing due to several reasons: * A faulty primary side power semiconductor. You should check the condition of the primary rectifier and IGBT-module. * A faulty main circuit card. Inspect the smoothing and load capacitors and look for any insulation damages on the main circuit card. * A faulty secondary unit. Check the condition of the secondary diodes.
