STEPPER COUNT
The number of welds at the present step is displayed when the
STEPPER

)
on the

WELD COUNT
The present number of welds is displayed when the
WELD COUNT
(
See
(8).(b)
)
on the
MODE SWITCH
screen is turned on.
(5) MONITOR SET Screen
Set the conditions such as the welding current from which good or bad weldment is
judged, secondary voltage, etc.
If the monitored welding current, secondary voltage, etc., are out of those conditions,
a trouble signal is output, and it can be used to activate an alarm buzzer, alarm
lamp, and so on.

PULSE HIGH
If the percentage of the welding current pulse to the pulse width in the full wave
mode exceeds the percentage set in the PULSE HIGH, ERROR signal is
output.
