5.01 Introduction
This section describes basic maintenance procedures per-
formable by operating personnel. No other adjustments

cedures refer to PAK Master 100XL Plus Automated
Power Supply Service Manual 0-2812.
5.02 General Maintenance
WARNING
Disconnect primary power to the system before dis-
assembling the torch, leads, or power supply.
To clean the unit, open the enclosure (refer to Section 5.05-
A, Opening Enclosure) and use a vacuum cleaner to re-
move any accumulated dirt and dust. The unit should
also be wiped clean. If necessary, solvents that are rec-
ommended for cleaning electrical apparatus may be used.
This schedule applies to all types of non-liquid cooled
plasma cutting systems. Some systems will not have all
the parts listed and those checks need not be performed.
NOTE
The actual frequency of maintenance may need to
be adjusted according to the operating environ-
ment.
A. Maintenance Schedule
Daily Operational Checks or Every Six Cutting Hours:
1. Check torch consumable parts, replace if damaged
or worn.
2. Inspect torch for any cracks or exposed wires, re-
place if necessary.
3. Check plasma and secondary supply and pres-
sure/flow.
4. Purge plasma gas line to remove any moisture
build-up.
5. Inspect input power cable for damage or exposed
wires, replace if necessary.
Weekly or Every 30 Cutting Hours:
1. Check fan for proper operation and adequate air
flow.
2. Vacuum dust and dirt out of the entire machine.
CAUTION
Do not blow air into the power supply during clean-
ing. Blowing air into the unit can cause metal par-
ticles to interfere with sensitive electrical compo-
nents and cause damage to the unit.
Six Months or Every 720 Cutting Hours:
1. Check the in-line air filter(s), clean or replace as
required
2. Check cables and hoses for leaks or cracks, replace
if necessary.
3. Check all contactor points for severe arcing or pits,
replace if necessary.
B. Two Stage Air Filter Element Replacement
NOTE
The Two Stage Air Filter has two Filter Elements.
When the Filter Elements become dirty the Power
Supply will continue to operate but cut quality may
become unacceptable.
1. Remove power from power supply.
2. Shut off air supply and bleed down system be-
fore disassembly before changing Filter Elements.
WARNING
Always turn off the air supply and bleed the sys-
tem before disassembling the Filter Assembly as
injury could result.
3. Loosen the two bolts on the top of the Filter As-
sembly enough to allow the Filter Elements to
move freely.
4. Note the location and orientation of the old Filter
Elements.
5. Slide out the old Filter Elements.
6. Slide the replacement Filter Elements into the Fil-
ter Assembly the same as noted in Step 4 above.
7. Hand tighten the two bolts evenly, then torque
each bolt to 20 - 30 in-lbs (2.3 - 3.4 Nm).
8. Slowly apply air pressure to the assembly check-
ing for leaks.
