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. |
|
|
|
|
Excessively long and erratic arc. | 1. Check for proper configuration |
|
| and implementation of voltage |
|
| sensing circuits. |
|
|
|
|
If Wire Feed Speed is in Question. | 1. Check system with K283 speed |
|
Inch Per Minute = (IPM) | meter tester. |
|
| 2. Manual Check by: |
|
| • Turning off all run in features of |
|
| the feeder. Cut wire flush to |
|
| weld gun electrode tip. Feed |
|
| wire for 6 seconds. Measure |
|
| feed wire length from the end of |
|
| the electrode tip to the end of |
|
| the feed wire. Multiple 10 to the |
|
| measured length. |
|
| Example: You mesured 24” , then |
|
| your results will be 240 IPM. |
|
| (10 x 24 = 240 IPM) |

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.
