What causes water-cooled pump issues in a Daihen OTC Welbee WB-P320E?
If your Daihen Inverter's water-cooled pump is behaving abnormally, check for water leakage from the cooling water hose and ensure sufficient cooling water is available. When using an air-cooled torch, verify that the LED of the TORCH key on the operation panel is off.
What to do if the power LED switch does not light on my Daihen OTC Welbee WB-P320E Inverter?
If the power LED switch on your Daihen Inverter doesn't light up when you turn on the power switch, it could be due to the primary power source not being supplied. Ensure that the primary power source is supplying between 340 to 460 V.
How to unlock the operation panel on a Daihen OTC Welbee WB-P320E?
If you cannot set the welding conditions using the operation panel on your Daihen Inverter, the erroneous prevention function may be enabled. To disable it, press and hold the ENTER key for three seconds or more.
What to do if Daihen Inverter overheats?
If the temperature inside your Daihen Inverter's welding power source exceeds the allowable range: * Leave the power on and let the cooling fan run for at least 10 minutes. * Turn off the power. * Clean any dust inside the welding power source. After the Inverter recovers, be careful not to exceed the rated duty cycle.
What causes an overcurrent error on a Daihen Inverter?
If an overcurrent is detected at the output side of your Daihen Inverter, check the following: * Ensure the chip at the end of the torch is not contacting the base metal. * Verify that the power cables for the base metal and torch sides are not short-circuited. The error code will disappear when the power switch is turned off.
What to do if Daihen OTC Welbee WB-P320E Inverter input voltage is too low?
If the input voltage for the primary side of your Daihen Inverter falls below the allowable range: * Check that the input voltage is between 340 and 460 V. * Verify the set value of internal function F20. The error code will disappear when the power switch is turned off.
What to do if the torch switch was on during Daihen OTC Welbee WB-P320E startup?
If the torch switch was on when you turned on the power switch of your Daihen Inverter: * Check that the torch switch is not pressed. * If the internal functions F29 to F32 are set to '4' (activate), check the connections of the terminal blocks for external connection. The error code will disappear when the status above is resolved.
Why can't I change the mode with the CRATER-FILL key on my Daihen Inverter?
If the mode does not change when you press the CRATER-FILL key on your Daihen Inverter, the internal functions F4, F48, or F51 may be set to 'ON'. Turn these settings to 'OFF'.
What to do if phase W is not connected on Daihen OTC Welbee WB-P320E?
If phase W of the input voltage for the primary side is not connected on your Daihen Inverter, check the input voltage for the primary side and the cable wiring for any issues. The error code will disappear when the power switch is turned off.
Why is the arc voltage not detected on my Daihen OTC Welbee WB-P320E?
If the arc voltage was not detected by your Daihen Inverter, check that the power cables (base metal and torch sides) and the voltage detection cable are properly connected. The error code will disappear when the power switch is turned off.
