COURSE OF ACTION
OUTPUT PROBLEMS
Machine often “noodle welds” (out-
put is limited to approximately 100
amps) when running a particular
procedure, especially a procedure
with high WFS.
Machine won’t produce full output.
For no apparent reason, the weld-
ing characteristics have changed.
The Power Wave is triggered to
weld, but there is no output.
1.Secondary current limit has been
exceeded, and the machine has
phased back to protect itself.
2. Adjust procedure or reduce load
to lower current draw from the
machine.
1. Input voltage may be too low,
limiting output capability of the
power source. Make certain that
the input voltage is proper,
according to the Rating Plate
located on the rear of the
machine.
2. Secondary current or voltage not
be properly calibrated. Check
values displayed on the Power
Feed 10/11 verses readings on
an external meter.
1. Check for proper Wire Feed
Speed setting. In CV MIG and
FCAW modes, check for proper
Voltage setting. In the MIG/MAG
pulse modes, check the Trim
setting. These controls are on
the wire feeder.
2. Check for proper shielding gas
mix and flow.
3. Check for loose or faulty weld
cables and cable connections.
1. Check for fault signals from the
I/O connector. Possible faults
are lack of water flow/ water flow
turned off.
If all recommended possible areas
of misadjustments have been
checked and the problem persists,
contact your local Lincoln
Authorized Field Service Facility.
