SECTION 5 TORCH:
SERVICE
5T.01 General Maintenance
NOTE!
Refer to Previous "Section 5: System Service" 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
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 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 com-
pressed 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 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.
