Hypertherm XPR170 Preventive Maintenance Program

Preventive Maintenance Program
XPR Instruction Manual 809480 31
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
If your cut-cycle is short, you can replace the following components more frequently.
* These parts are in the gas connect console.
