Error Codes for the Power Wave 455: Code 10675 and above.
ERROR CODES FOR THE POWER WAVE 455
As a troubleshooter aid, error code information will now persist on the user interface displays even after the fault is cleared. When a fault occurs that the user interface needs to display, welding will be inhibited for 5 seconds. If the fault has cleared, the error code information can then be removed from the displays by pressing the Reset button, by changing a user interface control or by starting a new weld.
The following is a list of possible error codes that the Power Feed™ 10M Dual Wire Feeder can output via the dis- play on this user interface.
Note: For any Err # listed below write down the error number for reference and try cycling power to see if the error clears itself. If not, refer to the What to Do column for the given Err.

(SYMPTOMS) | CAUSE | COURSE OF ACTION |
|
|
|
Display shows any of the following: |
|
|
|
|
|
Err 34 | Capacitor "A" under voltage | Excess voltage on the main capaci- |
| (Left side facing machine) | tors. May be caused by improper |
|
| input configuration. |
|
| When accompanied by an undervolt- |
Err 35 |
| age error on the same side, it indi- |
|
| cates no capacitor voltage present |
|
| on that side, and is usually the result |
| Capacitor "B" under voltage | of an open or short in the primary |
| (Right side facing machine) | side of the machine. |
|
|
|
Err 36 | Thermal error | Indicates over temperature. Usually |
|
| accompanied by Thermal LED. |
|
| Check fan operation. Be sure |
|
| process does not exceed duty cycle |
|
| limit of the machine. |
|
|
|
Err 37 | Softstart error | Capacitor precharge failed. Usually |
|
| accompanied by codes |
|
|
|
Err 41 | Secondary overcurrent error | The secondary (weld) current limit |
|
| has been exceeded. When this |
|
| occurs the machine output will |
|
| phase back to 100 amps, typically |
|
| resulting in a condition referred to as |
|
| "noodle welding" |
|
| NOTE: For the Power Wave 455/R |
|
| the secondary limit is 570 amps for |
|
| the standard stud, and 325 amps for |
|
| the STT stud and all single phase |
|
| operation. |
|
|
|
Err 43 | Capacitor delta error | The maximum voltage difference |
|
| between the main capacitors has |
|
| been exceeded. May be accompa- |
|
| nied by errors |
|

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.
