8.0 MAINTENANCE AND TROUBLESHOOTING
Always disconnect the AC power cable from the line voltage before
attempting to work on this welding power supply.
There are no user serviceable components located inside the Model 217 WDR. Do not
open the unit in an attempt to repair it. Contact Arc Machines, Inc. if the unit is
malfunctioning, or suspected of being broken. As such, no wiring diagram or internal circuit
drawing is provided.
8.1 GENERAL MAINTENANCE
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.
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 217 WDR
panel and the ground, electrode and gas quick-disconnects on all cables should be
performed. Damaged, dented or deformed connectors may cause poor or unsafe operation
or gas leakage. The O-rings inside the weld head ground, electrode and gas quick-
disconnects should be periodically cleaned and re-greased.
Precautions to follow for storing or handling:

Always keep weld heads in the protective containers they are shipped in, or
optional carrying case, until ready for use
