5.1 GENERAL TROUBLESHOOTING
If welding equipment doesnt work right despite compli-
ance with checklist inspect as follows:
A. With all power controls ON and other operating
controls at required settings, visually check all power
cables and connections for evidence of overheating
or sparking.
To avoid shock, do NOT touch electrode wire or
parts in contact with it, or uninsulated cable or
connections.
B. Isolate trouble to one part of the welding installation:
primary power supply, power source, Feeder or wire
guide train (casing, drive rolls, liners and contact tip).
If this inspection indicates trouble in the Feeder, use
Troubleshooting Guide, in the feeder manual.
Many troubleshooting situations require that the
power remain On and that power terminals in the
equipment carry voltage. Exercise extreme caution
when working on LIVE equipment. Avoid contact
with electrical components, except when testing
with an appropriate instrument.
Do not make any repairs to equipment unless you are
fully qualified, as described in the maintenance sec-
tion.
