GENERAL MAINTENANCE INSTRUCTION
WARNING
Always disconnect the AC power cable from the line voltage before attempting to
work with this welding power supply.
1. AIR FILTER - The M-227 power supply has one (1) foam air filter. Inspect this
air filter regularly. The foam filters 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 M227/207-CW or M207-CW Cooling Unit that requires the
same inspection and cleaning.
2. COOLANT - The water tank in the optional M227/207-CW OR M207-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
panels. Either wipe it off with a damp cloth or use a vacuum cleaner with a soft
brush . Where a vacuum brush cannot reach, use 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-227
panel and cable electrode, gas and water return quick-disconnects should be
performed. Damaged, dented or deformed connectors may cause poor or unsafe
operation and water or gas leakage.
