Error Code #

 

Indication

 

 

 

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 result-

 

 

 

 

 

 

 

ing 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.

 

 

 

 

 

 

 

 

 

43

Capacitor delta error

 

The maximum voltage difference between the main capacitors has been

 

 

 

 

 

 

 

exceeded. May be accompanied by errors 32-35.

 

 

 

 

 

 

 

 

 

 

49

Single phase error

 

Indicates machine is running on single phase input power. Usually

 

 

 

 

 

 

 

 

caused by the loss of the middle leg (L2).

 

 

 

 

 

 

 

 

Other

 

Error codes that contain three or four digits are defined as fatal errors.

 

 

 

 

 

 

 

These codes generally indicate internal errors on the PS Control Board.

 

 

 

 

 

 

 

If cycling the input power on the machine does not clear the error, try

 

 

 

 

 

 

 

reloading the operating system. If this fails, replace the control board.

 

 

 

 

 

 

 

 

 

 

 

 

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.
