7.3 GENERAL MAINTENANCE INSTRUCTIONS
CAUTION
Always disconnect the AC power cable from the line voltage before attempting to
work with this welding power supply.
1. AIR FILTER - The M-207A power supply has one (1) foam air filter.
Inspect this air filter regularly. The foam filter may be washed in water and
detergent, dried and reused or replaced. Do not operate unit without filter in
place. There is a similar filter on the Water Cooling Unit that requires the
same inspection and cleaning.
2. COOLANT - The water tank in the optional CW unit holds approximately
three (3) U.S. gallons. Check water level periodically. Using different
weld heads will remove water from tank over a period of time. Fill
the tank per instructions of section VIII.
3. Cleaning exterior and interior surfaces - Prolonged use in dusty shop or
outside environments may cause the outside surfaces to accumulate a coating
of dirt and dust. Do not use shop air (usually too wet) to blow dust particles
away from the panels. Either wipe it off with a damp cloth or use a vacuum
cleaner with a soft brush. Where a vacuum brush can not reach, use a clean,
soft paint brush and then vacuum.
CAUTION
Always disconnect the power input cable from the junction box or wall-plug before
cleaning.
DO NOT USE ANY SOLVENTS, SPRAY-ON CLEANERS OR WATER on any
of the inside parts. All outside surfaces may be cleaned with a soft cloth or sponge,
damp, NOT SOAKED, with a mild detergent solution.
4. INPUT/OUTPUT PANEL CONNECTIONS - Periodic inspection of the M-
207A panel and the electrode, gas and water return quick-disconnects on all
cables should be performed. Damaged, dented or deformed connectors may
cause poor or unsafe operation and water or gas leakage. The O-ring inside
the weld head electrode and gas quick-disconnects should be periodically
cleaned and re-greased.
