Cutting Area And Operation Effects; External Cutting Area - Hypertherm XPR Series Preventive Maintenance Program

Preventive Maintenance Program

Cutting area and operation effects

The component replacement schedule is for reference only. Your cutting area conditions and
operations can have an effect on your component replacement schedule.
These topics give the most common conditions and operations that increase the wear on some
components in your plasma system. This wear decreases system performance and component life.
If any of these conditions or operations apply, change your replacement schedule as suggested.
How much you need to change your schedule depends on how bad the condition is. If you have
questions about your replacement schedule, contact your OEM or regional Hypertherm Technical
Service team.

External cutting area

Consumables and torch assemblies stored in dirty cutting areas with no protection can collect
contamination, such as dirt and metal dust. If this contamination gets into the torch or coolant, it can
cause the following problems:
Prevent O-rings and seals on the torch heads and receptacles from sealing

Increase wear on torch heads and receptacles

Increase wear on the coolant pump

Cause unsatisfactory operation of the coolant flow switch


It can help to flush the coolant system or clean the flow switch. But, it can
be necessary to replace the coolant switch to fully repair the operation of
the coolant loop system.
The best solution is to store consumables and torch assemblies in a clean, protective space.
Another solution is to use compressed air to clean these parts before you use them.
If you cannot store your consumables and torch heads in a protective space, you can replace the
following components more frequently.
