[Cause]
An abnormality occurred in the contactor of the specified welding equipment, and the contactor output signal and contactor-on input signal have inconsistent states. If the contactor control type is "Standard" and an error message occurs before the program is executed, the contactor output signal or contactor-on input signal is already on.
[Remedy]
Check the status of the contactor and the status of the input/output signal.
