Possible 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 rollerhead must be reduced 0.25 mm. This can be done by the M10 screw on the back side.

See also in the manual X1 how to reset the upper pendulum rollerhead.

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!

Possible causes/checklist:

1. Take the wire and switch out of the air supply. Can you smoothly move both cylinders of the wire drive?
2. Check all rolls of wire drive system. Turn them by hand. All bearings ok?
3. Check the transport wheel of wire chopper unit, condition and distance (acc. to instruction manual)
4. Remove the belt of the motor for pendulum roller head and turn them by hand. Is it turning smoothly?
5. Check the same on profiling and chopper unit.
6. Now install the belts and tight them correctly.
7. Put in the wire and adjust the air regulator.
   Cylinder wire profiling unit 1.5 bar and cylinder wire chopper unit 2.0 bar.
8. Change the selector switch to “wire manual” and run the wire.
9. Take a look at welding rolls – is wire position correct?
10. Check profiling of copper wire, correct width and constant?
11. Weld a can with current and without current. Wire break?
12. Have you changed the wire? Use the old one to compare.
13. Check the tin mark on the wire. Ok?
14. Don’t forget to lubricate the profiling unit and chopper unit.

Possible causes:

• The movement (the back and forth) of the wire and the final wire break happens, because the analog signal is right on the threshold to start. You can solve the problem, when you increase the „Hertz“ setting of the frequency converters U4 and U6.
  • Place the programming display on the converter U4 and change the parameter C19 from 5Hz to 7Hz, and do the same for the converter U6.
• A second reason for this phenomena could be the incorrect position of the analog sensors B1 and B2, see the following description, which is explained for the CM X8, but is valid also for the other automatic welders.
