5.01 Introduction

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

dures refer to PAK Master 50XL PLUS Power Supply (CE)
Service Manual 0-2781.

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 ad-
justed according to the operating environment.

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 pressure/

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 (see subsection B below)

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. Optional Dry Air Filter Element

Replacement

NOTE

The XL PLUS Power Supply (CE) shuts down au-
tomatically when the Filter Element becomes com-
pletely saturated. The Filter Element can be re-
moved from its housing, dried out, and reused.
Allow 24 hours for Element to dry.

1. Remove power from power supply.

2. Shut off air supply and bleed down system before

disassembly to change Filter Element.
