SECTION 5 TORCH:
SERVICE
5T.01 General Maintenance
NOTE
Refer to Previous "Section 5: System" for com-
mon 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 elec-
trical 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 Con-
nector 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 ele-
ments” that may react with the atmosphere.
This reaction can leave contaminants inside
the torch. Either of these conditions can lead
to inconsistent performance or poor parts life.
