e. WORK DETECT MONITOR
The presence or absence of work piece can be detected by measuring the head travel distance
from the beginning of SQD through the end of SQZ. The presence or absence and overlapping
of work piece can be detected.
In WORK DETECT LIMIT , set the upper limit (HIGH) and the lower limit (LOW) in
consideration of the difference between the head travel distance from the beginning of SQD
through the end of SQZ and the presence or absence of a work piece to detect.
In WORK DETECT MONITOR , the measured value of the head travel distance from the
beginning of SQD through the end of SQZ at welding is displayed.
In WORK DETECT LIMIT , you can set a value checking the measured value of work piece
detection when the head is actually operated.
To use the work piece detection function, the used displacement gauge should be ready at any
time to measure the displacement from force releasing to force applying (the measurement range
of the displacement gauge is larger than distance between electrodes at force releasing).
Otherwise, the work piece detection will not be done properly.
f. DISPLACEMENT LIMIT
g. DISPLACEMENT DELAY TIME
h. DISPLACEMENT MONITOR
Measures the degree of work piece collapse by measuring the head travel distance from the pre-
check start to the displacement delay time elapses.
The degree of collapse in fusing welding can be controlled.
In DISPLACEMENT LIMIT , set the upper limit (HIGH) and the lower limit (LOW) to control
the head travel distance (the degree of work piece collapse) from the pre-check start to the
displacement delay time elapses.
In DISPLACEMENT DELAY TIME , set the delay time from the end of WE3 to the
displacement measurement. Since the degree of work piece collapse changes by remaining heat
of electrode even after welding, set the time in consideration of the timing to make a
displacement measurement. Up to the time set in HOLD can be set.
In DISPLACEMENT MONITOR , the head travel distance (the degree of work piece collapse)
from the pre-check start to the displacement delay time elapses is displayed.
