ESAB CUTMASTER 40
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
becomes coated with residue. This buildup can
affect the 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 in the ATC Male Connector requires
lubrication on a scheduled basis. This will al-
low 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.

5T.02 Inspection and Replacement
of Consumable Torch Parts
Remove the consumable torch parts as follows:
5T-1
ATC Male Connector

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.
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.
