Troubleshooting
If the welding equipment does not work correctly, inspect as follows:
1.
With all power controls in position on and other operating controls at required settings,
visually check all power cables and connections for evidence of overheating or
sparking.
WARNING!
To avoid shock, do not touch electrode wire or parts in contact with it, or
uninsulated cable or connections.
2.
Check all gas hoses, connections, flowmeters and regulators for possible sources of
leakage, breakdown or intermittent failure.
3.
Isolate trouble to one part of the welding installation: primary power supply, power
source, wire feeder or wire guide train (casing, drive rolls, liners and contact tip). If this
inspection indicates trouble in the wire feeder, refer to the wiring diagram.
WARNING!
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.
CAUTION!
Do not make any repairs to equipment unless you are fully qualified, as
described in the maintenance section.
4.
Check that the power supply is set to "Suitcase" or "MIG" to make sure that the
MobileFeed will work.
