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 becomes 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 electrical contact cleaner using a cot-
ton 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
Connector requires lubrication on a sched-
uled 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 tempera-
tures or may contain "unknown elements" 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.
