e. POWER
The power during which current was supplied in the course of WELD1, WELD2 and WELD3
operations are displayed. The value calculated from current and voltage (current x voltage) is
displayed. To display the voltage, you need to measure the secondary voltage by connecting the
voltage detecting cable. The latest measured value welded with the displayed SCHEDULE No.
is displayed.
f. PULSE
The widest pulse among the supplied primary pulse current is displayed as a percentage of pulse
width in full wave mode. The pulse width in full wave mode varies with the frequency setting
(WELD TRANS FREQ). The latest measured value welded with the displayed SCHEDULE
No. is displayed.
NOTE: The value displayed on the MONITOR screen is the average of value sampled at each
welding pulse. Therefore, the value may differ from the measurement value of a weld checker
(MM-370B etc.).
g. STEP #
The present number of steps is displayed when STEPPER MODE is not OFF on the MODE
SELECT screen.
h. STEPPER COUNT
The number of welds in the present step is displayed when STEPPERMODE is not OFF on the
MODE SELECT screen
i. STEP2 REPEAT (Advanced Models ONLY)
Remaining number of repetition for the stepper used for STEP2 of the displayed SCHEDULE is
displayed when STEPPERMODE is not OFF on the MODE SELECT screen. The latest
measured value welded with the displayed SCHEDULE No. is displayed.
j. STEP RATIO (Advanced Models ONLY)
The step-up (-down) ratio is displayed when STEPPERMODE is not OFF on the MODE
