Error Codes - Kemppi MasterTig 235ACDC GM Operating Manual

Tip: For checking the correct welding settings, you can also use Weld Assist.
Varying welding performance
• Check that the welding torch is physically intact and the nozzle is clear of any obstructions.
• Check that the welding torch is not overheating.
• Check that the earth return clamp is properly attached to a clean surface of the workpiece.

Proposed action
Restart the power source. If problem persists, contact
Kemppi service. Note: The equipment operation is limited
when this error occurs.
Restart the power source. If problem persists, contact
Kemppi service.
Restart the power source. If problem persists, contact
Kemppi service.
Do not shut down, let the fans cool the machine. If fans are
not running, contact Kemppi service.
Check the mains cable and its connectors. Check the
voltage of mains supply.
Clean the filters and clear any dirt from the cooling channel.
Check that the cooling fans are running. If not, contact
Kemppi service.
Do not turn off the cooler. Let the liquid circulate until the
fans cool it down. If fans are not running, contact Kemppi
service.
Check the liquid level in the cooler. Check hoses and con-
nectors for blockage.
Check the cooler connections. Ensure that the cooling is
turned off in the settings menu, if the cooler is not in use.
Remove any unintended resistive load connected to the
welding equipment and restart the power source.
Reduce welding power.
Check the mains voltage and/or the supply cable.
Check the mains voltage.
Check the mains voltage and/or the supply cable.
