1 Spot Welding Application Using a Motor Gun
1.12 Tip Wear Detection and Wear Compensation (Motor Gun)
When the tip mounting position error is detected with a job for tip

mounting position error detection.
By adding tags for tip mounting position error detection (TWC-AE, TWC-
BE) to the dry spot instruction (SVGUNCL), tip mounting position errors
can be detected.
• Dry spot touch motion (TWC-AE)
The gun axis position is acquired when the movable side tip touches
the fixed side tip.
Execute SVGUNCL instruction (dry spot) for the dry spot touch
motion.

• Movable side tip detecting motion (TWC-BE)
The gun axis position is acquired when the movable side tip position
is detected.
Execute SVGUNCL instruction (dry spot) for the movable side tip
detecting motion.
