PROBLEMS

(SYMPTOMS)

POSSIBLE

CAUSE

RECOMMENDED

COURSE OF ACTION

 

General degradation of the weld per- 1.Check for feeding problems, bad

 

formance

 

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.

 

 

If all recommended possible areas of

 

 

 

 

 

 

 

 

 

 

 

 

 

Excessively long and erratic arc.

1. Check for proper configuration misadjustments have been checked

 

 

 

and implementation of voltage and the problem persists, contact

 

 

 

sensing circuits.

The feeder will not cold inch wire.

1. Check for fault signals from the

 

 

 

I/O connector. Possible faults are

 

 

 

lack of water flow/ water cooler

 

 

 

turned off.

 

 

 

 

 

 

 

 

 

Arc loss fault on robot.

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.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
