Cut-cycle times
When the cut-cycle
time
is very short, relays operate more frequently. The system also pierces more
frequently during very
short cut-cycle times. Examples of
very short
cut-cycle
times
are when you cut many small holes or make markings for numbers and letters.
Cycle times that are
very short
can cause
these problems:
- Decreased life of pilot arc relay contact pads
- Decreased life of the starting components, such as the high-frequency transformer and the high-frequency ignition Printed Circuit Board (PCB)
- Increased misfires and error codes
If your usual cut-cycle times are very short, replace these components more frequently:
