MAINTENANCE
Maintenance of the torch will normally consist of a general cleaning of the wire guide
system, including tubes, 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.
If repairs do become necessary, any part can easily be replaced by a qualified shop
maintenance man.
Your Cobramatic is designed to provide years of
reliable service. Normal wear and component
failure may require occasional service.
The number of units in operation and the
importance of minimal “down time” will deter-
mine to what extent spare parts should be
stocked on hand. See the "Recom-
mended spare parts list" for the most
commonly replaced parts.
CHANGING THE CONDUIT
Method 1 - Using Conduit Coupler Fitting
1. Lay torch out as straight as possible.
2. Lay out new conduit in front of torch as
shown.
3. Remove spiral wrap from both
ends of cable assemblies.
4. Using the conduit coupler fitting,
(MK P/N 757-0012), couple the old
conduit to the new one.
5. Pull the old conduit out while an
assistant pushes the new one in.
