5.0 MAINTENANCE AND TROUBLE-SHOOTING
Always disconnect the AC power cable from the line voltage before
attempting to work with this welding power supply.
5.1 GENERAL MAINTENANCE
• COOLANT - the water tank in the optional Model 205-
CW cooling unit holds
approximately 0.75 gallons (2.8 liters) of fluid. Check the fluid level periodically. The
use of different weldheads will remove fluid from the tank over a period of time. Fill
the tank per instructions in Section 6.1 COOLING UNIT.
• 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 to blow dust particles away from the panels since it is
usually too wet. Use a vacuum cleaner with a soft brush. Where a vacuum brush
cannot reach use a clean soft paint brush and then vacuum.
• INPUT/OUTPUT PANEL CONNECTIONS - periodic inspection of the Model 205
panel as well as electrode/gas/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 weldhead electrode and
gas quick-disconnects should be periodically cleaned and re-greased.
• Precautions to follow for storing or handling:
Always keep weldheads in the protective containers they are shipped in or in an optional
carrying case until ready for use. Residual coolant should be drained from the weldhead
cables to prevent corrosion.
