The copper wire grooves do not wear straight
Cause:
The upper pendulum roller might be not leveled properly. When regrooving the
upper disc for example 0.50 mm in diameter, the height of the pendulum
roller head must be reduced 0.25 mm. This can be done by the M10 screw on the
back side.
See also in the manual X1 (see attachment) how to reset the upper pendulum roller head.
NOTE: The description manual is based on a CM X1 welder, but it works very similar for our other welders.
ATTENTION: Do not touch the red marked screws!
