A. GUN NO.
Shows the gun No. Select a number by pressing the page key
B. TIP HIT COUNT (CURRENT, TOLERANCE)
"CURRENT" shows the number of times the SVSPOT instruction was
carried out. When the current value exceeds the allowable value (TOL-
ERANCE,) a signal to request tip replacement is output.
C. WEAR (MOVABLE SIDE) (CURRENT, TOLERANCE)
"CURRENT" shows the current amount of electrode wear on the mov-
able side. When the current value exceeds the allowable value (TOL-
ERANCE,) a signal to request tip replacement is output.
D. WEAR (FIXED SIDE) (CURRENT, TOLERANCE)
"CURRENT" shows the current amount of electrode wear on the fixed
side. When the current value exceeds the allowable value (TOLER-
ANCE,) a signal to request tip replacement is output..
E. TCP ADJUSTMENT VALUE
Shows the amount of shift from the TCP.
F. GUN STROKE ADJUSTMENT
Shows the adjusted amount of gun stroke.
G. BASE POS (MOVABLE SIDE)
Registers the first detected position (position where the signal from the
sensor is input) after the reference data is cleared. For the second
detection or later, calculates the difference from the reference position
as the wear amount.
H. BASE POS (FIXED SIDE)
Registers the first detected position (position at dry spotting) after the
reference data is cleared.
For the second detection or later, calculates the difference from the
reference position as the wear amount.
