If the shielding gas supply on your Daihen Inverter doesn't stop, it could be due to the gas check lamp being lit. Press the GAS CHECK key to stop the gas check. Alternatively, there might be an issue with the gas solenoid valve (SOL). In this case, check the operation of the gas solenoid valve (SOL) on the wire feeder.
What does E-510 alarm mean on my Daihen OTC CPTX-I 400 2W and how can I fix it?
If your Daihen Inverter is alarming E-510, it could be due to several reasons: * There is no water in the tank. Pour water into the tank to fit the range. * There is trouble with the pressure switch PS. Check PS. * The pump does not operate. Check the pump. * There is trouble with the relay. Check CR. * There is trouble with the program circuit. Check PCB6?PCB1. * There is insufficient water circulation. Check the flow amount of the in and out water in the welding torch.
Why can't I set the current and voltage on my Daihen OTC CPTX-I 400 2W Inverter?
If the Daihen Inverter's current and voltage cannot be set, it could be due to several issues. It may be a problem with the control circuit, in which case you should inspect and replace PCB P30256P if necessary. Alternatively, there could be a problem with the filter circuit, requiring inspection and possible replacement of PCB P30110R. Another possibility is a problem with the remote control; inspect the cable and plug, and replace them or the remote control if needed. Finally, there might be an error in voltage detection; check the connection for CN5 on circuit board P30256P.
What to do if the wire is not fed in my Daihen OTC CPTX-I 400 2W Inverter?
If your Daihen Inverter is not feeding wire, the issue could stem from a few potential causes. First, check for incomplete insertion or breakage of the control cable for the wire feeder; inspect the contacts of the plug and cable, and replace them if necessary. Second, there might be trouble with the motor control circuit, requiring inspection and possible replacement of PCB P30110Q. Lastly, a problem with the filter circuit could be the culprit; inspect and replace PCB P30110R if necessary.
Why does gas flow out without no-load voltage after pressing the welding torch switch on my Daihen OTC CPTX-I 400 2W Inverter?
If, after pressing the welding torch switch on your Daihen Inverter, gas flows out without no-load voltage, it could be due to trouble with the inverter main circuit. In this case, shut off the power supply and contact your dealer. Alternatively, there may be trouble with the control circuit. Inspect P30256P and P30066S, and replace them if necessary.
What to do if no gas flows out after pressing the torch switch on my Daihen OTC CPTX-I 400 2W Inverter?
If no gas flows out after pressing the torch switch on your Daihen Inverter, it could be due to several reasons. The discharge valve on the gas cylinder might be closed; open the valve. The gas cylinder might have insufficient gas pressure; check for proper gas pressure. There could be trouble with the gas solenoid valve SOL; inspect the gas solenoid valve SOL. Finally, there could be a disconnection of the torch switch cable or incomplete insertion to the receptacle; check wiring number 151,152.
Why is the indicator for main power supply (PL1) not lighting up on my Daihen OTC CPTX-I 400 2W?
If the indicator for the main power supply (PL1) does not light on your Daihen Inverter, it could be due to a few reasons. There might be trouble with PL1, so inspect PL1. The line disconnect switch may not be turned on, so inspect the power box. The input cables might not be securely connected, so inspect the input cable.
