007 The wire moves back and forth and finally the wire breaks!
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 CMX8, but is valid also for the other automatic welders.
