4. How to Operate Screens
4-12
(5) MONITOR SET Screen
Set the conditions for determining a good or bad weld, including values for welding
current, upper or lower limits for the secondary voltage, etc.
If the monitored welding current, secondary voltage, etc., do not meet the set
conditions, a caution signal is output, and can be used to activate an alarm buzzer,
alarm lamp, or similar event.

WELD2 HIGH 9.99kA 9.99V 99.99kW 100%
LOW 0.00kA 0.00V 00.00kW
WELD3 HIGH 9.99kA 9.99V 99.99kW 100%

(e)
(a) SCHEDULE #
Input the No. of the SCHEDULE to monitor (to set the schedules).
(b) CURRENT
Set the upper limit (HIGH) and lower limit (LOW) of the welding current for each
of WELD1, WELD2 and WELD3.
(c) VOLT
Set the upper limit (HIGH) and lower limit (LOW) of the secondary voltage for
each of WELD1, WELD2 and WELD3.
(d) POWER
Set the upper limit (HIGH) and lower limit (LOW) of the electric power for each of
WELD1, WELD2 and WELD3.
(e) PULSE
If the ratio of welding current pulse / pulse width in full wave mode exceeds the
percentage set in the PULSE HIGH, an error signal is output. Pulse width is
expressed assuming that the full wave is 100%.
(Note) Upper/Lower limit judgment value when STEPPER MODE is set to ON
The upper/lower limit judgment value set here is for the current when a welding
is performed, not for the initial setting.
Therefore, when STEPPER MODE is set to ON to perform step-up
(step-down) for the initial setting, the upper/lower limit judgment value is
stepped up or down automatically.
Example) When the current is set to 2
kA, HIGH; 2.2
kA, LOW; 1.8
kA.
When the step becomes 150%, HIGH and LOW become as follows.
HIGH: 2.2 x 1.5 = 3.3
kA
LOW: 1.8 x 1.5 = 2.7
kA
