    What to do if Kemppi X3 stops and shows Err 4 with overheating indicator?

      Jennifer MosleyJul 27, 2025
      If your Kemppi Welding System stops, the overheating indicator is lit, and Err 4 is displayed, it means the machine has overheated. Ensure unrestricted cooling air flow. The machine’s duty cycle may have been exceeded. If no other damage occurs, the fan will start, and the machine will recover in a few minutes. If the problem continues, contact a Kemppi service representative.

      Nathan ZunigaAug 2, 2025
      If your Kemppi Welding System stops and displays Err 2 or Err 3, it indicates that the mains voltage is either too low (Err 2) or too high (Err 3). The machine will automatically recover when the mains voltage is within the recommended range of 342 – 484 V.

    Why is my Kemppi X3 Welding System producing poor welding results?
    • A
      Arthur NicholsAug 14, 2025
      Several factors can affect welding quality. Here's what to check: * Verify wire feed calibration. * Ensure the earth return clamp is properly attached to a clean contact point, and that the cable and connectors are intact. * Confirm the voltage and wire speed settings on the control panel are correct for the wire size and type. * Check the shielding gas flow rate at the gun nozzle. * Make sure the shielding gas is suitable for the filler wire used. * Ensure constant wire feed, adjusting if needed. * Check for irregular mains voltage.

    How to troubleshoot Kemppi X3 Welding System main switch indicator not turning on?
    • S
      Shannon MooreAug 20, 2025
      If the main switch indicator on your Kemppi Welding System doesn't turn on, the machine isn't receiving mains voltage. Check the mains fuses, the mains cable, and the wall plug.
