Section D           Maintenance
Periodic Maintenance
Your Cobramatic
®
System is designed to provide years of reliable 
®
service.Maintenance of the torch 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, qualifi ed shop maintenance personnel can 
easily replace any part.
