5.0 MAINTENANCE AND TROUBLESHOOTING

A. CLEANING

Periodically, remove the cover from the power source and blow accumulated

dust and dirt from the air passages and interior components by using clean low

pressure air. The frequency of cleaning required depends upon the environment

in which the power source is used.

It is imperative that all air passages be kept as clean as possible in order to allow

adequate air flow to provide proper cooling.

After cleaning with low pressure air, check for and tighten any loose hardware,

including all electrical connections. Check for frayed and/or cracked insulation

on all power cables and replace if necessary.

B. INSPECTION AND SERVICE

Keep the power source dry, free of oil and grease, and protected at all times from

damage by hot metal and sparks.

C. FAN MOTOR

Keep the fan motor free of accumulated dust and lint.

D. TRANSFORMER

Other than periodically cleaning the dust and dirt from the transformer, no

maintenance is required. Ensure that only clean, dry, low pressure air is used.

E. WIRE FEEDER CONTROL CIRCUITS

These circuits are protected by two 10 amp circuit breakers mounted in the front

panel. If these open, the contactor and wire feeder will not operate.

F. OVER TEMPERATURE PROTECTION

If the power source reaches an abnormally high internal temperature, the

thermal protection will deenergize the contactor circuit, shutting down the power

source but leaving the cooling fan on. After the power source has cooled to a

safe level, the thermal protection will automatically reset. While de-energized,

the contactor and wire feeder cannot be operated.

G. TROUBLESHOOTING

If the power source is operating improperly, the following troubleshooting

information may be used to locate the source of the trouble.

Check the problem against the symptoms in the following troubleshooting guide

(Table 5-1.) The remedy for the problem may be quite simple. If the cause

cannot be quickly located, open up the unit and perform a simple visual

inspection of all the components and wiring. Check for proper terminal

connections, loose or burned wiring or components, blown fuses, bulged or

leaking capacitors, or any other sign of damage or discoloration.
