Observe all Safety Guidelines detailed throughout this manual

Error Code #

Indication

11

CAN communication bus off.

Probably due to excessive number of communication errors.

12

User Interface time out error.

UI is no longer responding to the Power Source. The most likely

cause is a fault/bad connection in the communication leads or con-

trol cable.

21

Unprogrammed Weld Mode.

Contact the Service Department for instructions on reloading the

Welding Software.

22

Empty Weld Table.

Contact the Service Department for instructions on reloading the

Welding Software.

23

Weld Table checksum error.

Contact the Service Department for instructions on reloading the

Welding Software.

31

Primary overcurrent error.

Excessive Primary current present. May be related to a short in the

main transformer or output rectifier.

32

Capacitor "A" under voltage

Low voltage on the main capacitors. May be caused by improper

(Left side facing machine)

input configuration.

33

Capacitor "B" under voltage

When accompanied by an overvoltage error on the same side, it

(Right side facing machine)

indicates no capacitor voltage present on that side, and is usually

the result of an open or short in the primary side of the machine.

34

Capacitor "A" over voltage

Excess voltage on the main capacitors. May be caused by improp-

(Left side facing machine)

er input configuration.

35

Capacitor "B" over voltage

When accompanied by an under voltage error on the same side, it

indicates no capacitor voltage present on that side, and is usually

(Right side facing machine)

the result of an open or short in the primary side of the machine.

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.

37

Soft start error

Capacitor precharge failed. Usually accompanied by codes 32-35.

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: The secondary limit is 570 amps for the standard stud, and

325 amps for 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.
