What to do if Kemppi HiArc M 500R overheats and shows Err 4?
The Kemppi Welding System may have stopped working due to overheating or exceeding the duty cycle. Ensure unrestricted airflow for cooling. If the duty cycle has been exceeded, the fan should start, and the machine will recover in a few minutes. If the problem persists, contact a Kemppi service representative.
What to do if Kemppi Welding System shows Err 2 or Err 3?
The Kemppi Welding System has stopped because 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.
What to do if Kemppi HiArc M 500R Welding System displays Err 43 error?
The Kemppi Welding System stopped working and shows Err 43 because the wire feeder motor is overloaded. Check that you are using the correct wire type and that the wire feed path is not blocked.
Why is the Kemppi Welding System producing poor welding results?
Several factors can affect the welding quality. Here's what to check: * Verify wire feed calibration. * Ensure the earth return clamp is properly attached and the contact point is clean, 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 being used. * Make sure the shielding gas flow rate at the gun nozzle is correct. * Ensure the shielding gas is suitable for the filler wire used. * Check that the wire feed is constant, and adjust if necessary. * Verify that the mains voltage is not too irregular.
How to troubleshoot the main switch indicator on Kemppi HiArc M 500R Welding System?
The main switch indicator on the Kemppi Welding System isn't turning on because the machine isn't receiving mains voltage. Check the mains fuses, the mains cable, and the wall plug.
