Why Daihen OTC Welbee Inverter W400 Welding System power LED switch is not lighting?
If the power LED switch does not light even when the power switch is turned on for your Daihen Welding System, it means the primary power source is not supplied. Supply the primary power source between 340 to 460 V.
What to do if Daihen OTC Welbee Inverter W400 Welding System primary side voltage is too low?
If the input voltage for the primary side of your Daihen Welding System fell below the allowable range, check that the input voltage is between 340 and 460 V. Also, check the set value of internal function F20. The error code will disappear when the power switch is turned off.
What to do if Daihen OTC Welbee Inverter W400 Welding System input voltage is out of range?
If the input voltage for the primary side of your Daihen Welding System is outside the allowable range, check that the input voltage is between 340 and 460 V. The error code will disappear when the power switch is turned off.
What to do if Daihen OTC Welbee Inverter W400 Welding System displays error of control power?
If your Daihen Welding System displays an error of control power, check that there is no abnormality (e.g., short-circuit) in the cables. The error code will disappear when the power switch is turned off.
What to do if the Daihen OTC Welbee Inverter W400 power switch has tripped?
If the power switch has tripped on your Daihen Welding System, it indicates a leak has occurred in the welding power source. DO NOT turn on the power switch. Contact your dealer.
What to do if Daihen OTC Welbee Inverter W400 Welding System detects over current at the output side?
If your Daihen Welding System detects an over current at the output side, check that the chip at the end of the torch is not contacting the base metal. Also, verify that the power cables, including those for the base metal and torch, are not short-circuited. The error code will disappear when the power switch is turned off.
What to do if temperature warning LED lights on Daihen OTC Welbee Inverter W400 Welding System?
If the "Temperature WARNING" LED lights and an error code is displayed when the power switch is turned on, it means that the protection circuit has been activated due to a temperature error. Leave the system untouched with the power on, let the cooling fan run for at least 10 minutes, and then turn off the power. After doing so, clean the dust inside the welding power source.
