Why Yeswelder Welding System control PCB keys don't function and there is no response when pushing the torch trigger?
If the control PCB keys do not function and there is no response when pushing the torch trigger, the cutting machine might have crashed. To solve this, shut down the machine and restart it.
What to do if Yeswelder CUT-55DS Welding System control PCB keys work normally, but there is no response when pushing the torch trigger?
If the control PCB keys work normally, but there is no response when pushing the torch trigger, check the following: If the LED1 on the main board is on, the control PCB is damaged. If the LED1 on the main board is off, check the torch trigger and torch trigger wire.
