NOTE!

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 aect the pilot arc initia-
tion 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 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 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 lm 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 con-
taminants inside the torch. Either of these conditions
can lead to inconsistent performance or poor parts
life.
