What is the correct position of the calibration crown?
The center of the calibration crown (tooling) should be X = 2 – 3 mm behind the center of the pendulum roller head.
The screw with the lock nut has a red seal and must not be changed. This is used to fix the position on the longitudinal axis of the tool carrier with regard to the welding centre.
NOTE:
If you have to change the setting of the calibration crown, you have to loose the lock nut and adjust with the M10 screw accordingly.
