Routine Maintenance
The system is designed to require little regular maintenance under normal use. The following maintenance
checks, are suggested to keep your system in top running condition.
Torch and Torch Leads (See also

at the end of this section)
Inspection
Inspect the torch and torch leads on a routine basis.
• The torch consumable parts and torch main body should always be inspected prior to cutting. Worn or
damaged parts can cause gas and water leaks which can affect the cut quality. Check for pitting and burn
marks on the consumable parts and replace, if necessary. See
Changing Consumable Parts
in
Section 6
.
• Ensure that all connections are tight, but do not overtighten.
• The torch leads should be checked occasionally for cracking and damage.
Power Supply (See also

Inspection and Cleaning
Inspect the power supply on a routine basis.
• Check the exterior for any damage. If there is damage, ensure it does not affect safe operation of the power
supply.
• Remove covers and inspect the interior. Check wiring harnesses and connections for wear and damage.
Check for loose connections, and look for areas of discoloration due to overheating.
• At the rear of the power supply, inspect the filter element of the water/coolant sub-assembly. In the event
that the filter becomes excessively dirty, torch coolant flow can slow down causing the flow switch to open
(turn off) and make the coolant flow interlock status LED illuminate. The filter changes to a brown color
when dirty. Replace the filter element (027005) when it starts to turn color.
• Every two weeks, inspect the air filter in the front panel of the power supply by removing the access cover
and lifting the filter out. Replace filter (027441) when dirty.
• Every six months, flush power supply of its torch coolant and replace with new coolant (028872). Also
replace the water filter (027005) every six months.
• Every six months, clean pump strainer with a mild soap and water solution.
Note: Remove pump from system before removing strainer to avoid any debris from falling into pump
housing. See Fig. 8-0.
