CAUTION
PROBLEMS
(SYMPTOMS)
POSSIBLE
CAUSE
RECOMMENDED
COURSE OF ACTION
General degradation of the weld per-
formance
Excessively long and erratic arc.
The feeder will not cold inch wire.
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.
4. Check the actual current dis-
played on the Power Feed 10 vs.
actual current measured via exter-
nal meter.
5. Check the actual voltage dis-
played on the Power Feed 10 vs.
actual voltage measured via exter-
nal meter.
6. Check the actual WFS displayed
on the Power Feed 10 vs. actual
WFS measured via external
meter.
1. Check for proper configuration
and implementation of voltage
sensing circuits.
1. Check for fault signals from the
I/O connector. Possible faults are
lack of water flow/ water cooler
turned off.
1. Possibly caused by wire feeding
problem.
2. 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.
3. Problem – Conduit leading up to
the wire feeder from the wire reel
is too long. Solution – Use a short-
er length of conduit.
If all recommended possible areas of
misadjustments have been checked
and the problem persists, contact
