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
disassembling the torch or torch leads.
Frequently review the Important Safety Pre-
cautions at the front of this Manual. Be sure
the operator is equipped with proper gloves,
clothing, eye and ear protection. Make sure no
part of the operator’s body comes into contact
with the workpiece 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 becomes
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 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.
