SECTION 5 TORCH:
SERVICE
5T.01 General Maintenance
NOTE!
Refer to Previous "Section 5: Sys-
tem" for common and fault indicator
descriptions.
Cleaning Torch
Even if precautions are taken to use only clean air
with a torch, eventually the inside of the torch be-
comes coated with residue. This buildup can affect
the pilot arc initiation and the overall cut quality of
the torch.
WARNING
Disconnect primary power to the
system before disassembling the
torch or torch leads.
DO NOT touch any internal torch
parts while the AC indicator light of
the Power Supply is ON.
The inside of the torch should be cleaned with electri-
cal contact cleaner using a cotton swab or soft wet
rag. In severe cases, the torch can be removed from
the leads and cleaned more thoroughly by pouring
electrical contact cleaner into the torch and blowing
it through with compressed air.
CAUTION
!
Dry the torch thoroughly before
reinstalling.
O-Ring Lubrication
An o-ring on the Torch Head and ATC Male Connec-
tor requires lubrication on a scheduled basis. This
will allow the o-rings to remain pliable and provide
a proper seal. The o-rings will dry out, becoming
hard and cracked if the lubricant is not used on a
regular basis. This can lead to potential performance
problems.
It is recommended to apply a very light film of o-
ring lubricant (Catalog # 8-4025) to the o-rings on
a weekly basis.

NOTE!
DO NOT use other lubricants or
grease, they may not be designed
to operate within high temperatures
or may contain "unknown elements"
that may react with the atmosphere.
This reaction can leave contami-
nants inside the torch. Either of
these conditions can lead to incon-
sistent performance or poor parts
life.
