Pin No. Name Function
22, 24 IN8
_AC/DC24V
These pins are used to detect trigger input set by IN8 using
voltage.
Input 24V AC or DC voltage at least 10 ms prior to the flow
of welding current, and stop the input after the current flow.
If no welding current flows while this terminal is supplied
with voltage, a lack of current error is displayed when the
voltage input stops.
