Cut-cycle time
When the cut-cycle is very short, relays operate more frequently. The system also pierces more frequently. Examples of
this type of cycle are when you cut many small holes or make markings for numbers and letters. These types of operations
can cause the following problems:
 Increase wear on pilot arc relay contact pads
 Increase wear on the starting components, such as the high-frequency transformer and the high-frequency ignition
board
 Increase misfires and error codes (020 or 021)
If your cut-cycle is short, you can replace the following components more frequently.
