The AVC Calibration is done on the AVC / OSC PCB (P/N 13D150313-01) located on the Servo
PCB mounting plate in labeled slot B 0/1. Locate the AVC adjustment trim pot R-40 on the
PCB (diagram 4). DO NOT ADJUST TRIM POTS R-80 AND R-81 (these are factory calibrated
for use with special application weld heads or fixtures not discussed in this section).
