What to do if my Kemppi HiArc M 400A stops and shows Err 4 with the overheating indicator?
If your machine has overheated, ensure that cooling air has unrestricted flow. If no other damage has occurred, the fan should start working, and the machine should recover within a couple of minutes.
How to fix Err 43 on my Kemppi Welding System?
If your Kemppi Welding System displays Err 43, it indicates that the wire feeder motor is overloaded. To resolve this, check that you are using the correct wire type and ensure that the wire feed route is unobstructed.
What to do if Kemppi HiArc M 400A Welding System stops with Err 4 and overheating indicator?
The machine has overheated. Ensure that cooling air has unrestricted flow. If the machine’s duty cycle has been exceeded, and no other damage has occurred, the fan will start, and the machine will recover within a couple of minutes. If the problem persists, no answer.
What to do if my Kemppi HiArc M 400A shows Err 2 or Err 3 and stops working?
The mains voltage is either too low (Err 2) or too high (Err 3). The machine recovers automatically when the mains voltage is in the recommended range (340–435 V).
How to fix Err 43 on Kemppi HiArc M 400A?
Err 43 indicates that the wire feeder motor is overloaded. Check that you are using the right wire type and that the wire feed route is unobstructed.
What to do if the main switch indicator on my Kemppi HiArc M 400A Welding System doesn't turn on?
If the main switch indicator does not switch on, it means the machine has no mains voltage. Check the mains fuses, the mains cable, and the wall plug.
Why is my Kemppi HiArc M 400A Welding System producing poor welding results?
Several factors can affect welding quality. Ensure the earth return clamp is properly attached to a clean contact point and that the cable and its connectors are intact. Also, verify the voltage and wire speed settings on the control panel are correct for the wire size and type you are using. Confirm that the shielding gas flow rate at the gun nozzle is correct and that the shielding gas is suitable for the filler wire. Check that the wire feed is constant and adjust if needed, and ensure the mains voltage is not too irregular.
Why won't the main switch indicator turn on in my Kemppi HiArc M 400A Welding System?
If the main switch indicator does not switch on, the machine has no mains voltage. Check the mains fuses, the mains cable, and the wall plug.
