(SYMPTOMS)
POSSIBLE AREAS OF
MISADJUSTMENTS(S)
RECOMMENDED
COURSE OF ACTION
General degradation of the weld
performance.
The Power Wave is triggered to
weld, but there is no output.
The feeder will not cold inch wire
Excessively long and erratic arc.
Arc loss fault on robot
1. Check for feeding problems, bad
connections, excessive loops in
cabling, etc..
2. Verify weld mode is correct for
processes.
3. The power source may require
calibration.
• Check the current calibration
• Check the voltage calibration
• Check the WFS calibration
1. Check for fault signals from the
I/O connector. Possible faults are
lack of water flow / water flow
turned off.
1. Check for fault signals from the
I/O connector. Possible faults are
lack of water flow / water cooler
turned off.
1. Check for proper configuration
and implementation of voltage
sensing circuits.
1. Possibly caused by wire feeding
problem.
2. Possible causes/solutions are:
• Problem - Conduit leading to the
wire feeder has bends or twists,
which can reduce the wire feed
speed.
• Solution - Remove bends and
twists from conduit.
• Problem – Conduit leading up to
the wire feeder from the wire reel
is too long.
• Solution – Use a shorter length of
conduit
If all recommended possible areas of
misadjustments have been checked
and the problem persists, contact
your local Lincoln Authorized
Field Service Facility.
