Manual 0-2962 5-1 SERVICE
SECTION 5:
SERVICE
5.01 Introduction
This section describes basic maintenance procedures per-
formable by operating personnel. No other adjustments
or repairs are to be attempted by other than properly
trained personnel.
WARNINGS
Disconnect primary power at the source before dis-
assembling the torch or torch leads.
Frequently review the Important Safety Precau-
tions at the front of this Manual. Be sure the op-
erator is equipped with proper gloves, clothing, eye
and ear protection. Make sure no part of the
operator’s body comes into contact with the work-
piece while the torch is activated.
CAUTION
Sparks from the cutting process can cause damage
to coated, painted, and other surfaces such as glass,
plastic and metal.
NOTE
Handle torch leads with care and protect them from
damage.
5.02 General Torch Maintenance
A. 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.
WARNINGS
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 elec-
trical 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.
