SECTION 5 MAINTENANCE

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.

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 cool-

ing.

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 one 10 amp circuit breaker mounted in the front panel. If it is open, the contactor and

wirefeeder will not operate.
