Periodic Maintenance
Your Cobramatic system is designed to provide years of reliable service.
Maintenance of the gun will normally consist of a general cleaning of the wire
guide system, including barrels, drive rolls, and conduits at regular intervals.
Remove spatter build-up from inside of nozzles with a hardwood stick.
The only parts on the Cobramatic system that are subject to normal wear are
the conduit, contact tips, gas cups, front body liners, wire guides, drive and
idler rolls. A supply of these parts should be maintained on hand.
The number of units in operation and the importance of minimal down time
will determine to what extent spare parts should be stocked on hand. See
the recommended spare parts list for the most commonly replaced parts.
If repairs do become necessary, qualified shop maintenance personnel can
easily replace any part.
