ERROR CODES FOR THE POWER WAVE®

The following is a partial list of possible error codes for the POWER WAVE® i400. For a complete listing consult the Service Manual for this machine.

POWER SOURCE–––WELD CONTROLLER

 

Error Code #

LECO

Indication

 

 

(FANUC#)

 

31

Primary (Input) overcurrent error.

49

Excessive Primary current present. May be related to a

 

 

 

switch board or output rectifier failure.

32

Capacitor “A” under voltage

50

Low voltage on the main capacitors. May be caused by

 

(right side facing the Switch PC Board)

 

improper input configuration, or an open/short circuit in the

33

Capacitor bank "B" under voltage

51

primary side of the machine.

 

(left side facing the Switch PC Board)

 

 

 

 

34

Capacitor "A" over voltage

52

Excess voltage on the main capacitors. May be caused by

 

(right side facing the Switch PC Board)

improper input configuration, excessive line voltage, or

 

 

35

Capacitor "B" over voltage

53

improper capacitor balance (see Error 43)

 

(left side facing the Switch PC Board)

 

36

Thermal error

54

Indicates over temperature. Usually accompanied by

 

 

Thermal LED. Check fan operation. Be sure process does

 

 

 

not exceed duty cycle limit of the machine.

37

Softstart (pre-charge) error

55

Capacitor precharge failed. Usually accompanied by

 

 

 

codes 32 and 33.

39

Misc. hardware fault

57

Unknown glitch has occurred on the fault interrupt circuit-

 

 

 

ry. Sometimes caused by primary over current fault, or

 

 

 

intermittent connections in the thermostat circuit.

43

Capacitor delta error

67

The maximum voltage difference between the main capac-

 

 

 

itors has been exceeded. May be accompanied by errors

 

 

 

32-35. May be caused by an open or short in the primary

 

 

 

or secondary circuit(s).

54

Secondary (output) over current

84

The long term average secondary (weld) current limit has

 

 

 

been exceeded. This error will immediately turn off the

 

 

 

machine output.

 

 

 

NOTE: The long term average secondary current limit is

 

 

 

450 amps.

 

 

 

 

 

 

 

A complete list of error codes is available in the

 

 

 

Diagnostics Utility (included on the POWER WAVE®

 

 

see com-

Utilities and Service Navigator CDʼs or available at

Other

 

www.powerwavesoftware.com).

 

plete

 

 

 

listing

Error codes that contain three or four digits are defined as

 

 

 

fatal errors. These codes generally indicate internal errors

 

 

 

on the Power Source Control Board. If cycling the input

 

 

 

power on the machine does not clear the error, contact the

 

 

 

Service Department

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.
