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 | |||

| 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.
