MasterTig 235ACDC, 325DC, 335ACDCOperating manual - ENTip: 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.5.1 Error codesErrorcodeError descrip-tion Possible reason Proposed action1 Power sourcenot calibratedPower source calibration has been lost. Restart the power source. If problem persists, contactKemppi service. Note: The equipment operation is limitedwhen this error occurs.2 Too lowmains voltageVoltage in mains network is too low. Restart the power source. If problem persists, contactKemppi service.3 Too highmains voltageVoltage in mains network is too high. Restart the power source. If problem persists, contactKemppi service.4 Power sourceis overheatedToo long welding session with high power. Do not shut down, let the fans cool the machine. If fans arenot running, contact Kemppi service.17 Phase is miss-ing frommains supplyOne or more phases are missing from themains supply.Check the mains cable and its connectors. Check thevoltage of mains supply.20 Power sourcecooling fail-ureCooling capacity is reduced in the powersource.Clean the filters and clear any dirt from the cooling channel.Check that the cooling fans are running. If not, contactKemppi service.24 Cooling liquidoverheatedToo long welding session with high power orhigh ambient temperature.Do not turn off the cooler. Let the liquid circulate until thefans cool it down. If fans are not running, contact Kemppiservice.26 Cooling liquidnot cir-culatingNo cooling liquid or circulation is blocked. Check the liquid level in the cooler. Check hoses and con-nectors for blockage.27 Cooler notfoundCooling is turned on in the settings menu, butcooler is not connected to power source orcabling is faulty.Check the cooler connections. Ensure that the cooling isturned off in the settings menu, if the cooler is not in use.34 Unknownwelding loadAn unknown load connected to DIX con-nectors.Remove any unintended resistive load connected to thewelding equipment and restart the power source.35 Too highmains currentCurrent drawn from the mains is too high. Reduce welding power.36 DC-link under-voltageDC-link voltage is too low. Check the mains voltage and/or the supply cable.37 DC-link over-voltageDC-link voltage is too high. Check the mains voltage.38 Mains voltagetoo high ortoo lowMains voltage is too high or too low. Check the mains voltage and/or the supply cable.© Kemppi 57/77 1920900 / 1939
