Manual 0-4989 5T-1 SERVICE

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 be-

fore 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 electri-

cal 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 Connec-

tor 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.
