Why do the net fuses blow during startup with my Kemppi MasterTig 1500 Welding System?
- L
  lgravesAug 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.

What to do if the Kemppi Welding System power source will not start and MMA open circuit voltage is 0 V?
- A
  Amy HernandezAug 21, 2025
  If the power source of your Kemppi Welding System doesn't start and the MMA open circuit voltage is 0 V, consider the following checks: * Net fuses * Supply cable condition * Main switch condition * Potentiometer condition * Control method selection switch condition * Auxiliary transformer condition * Condition of the primary rectifier and the IGBT-module * Flat cable condition
