POWER WAVE® AC/DC 1000
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.
CAUTION
Observe all Safety Guidelines detailed throughout this manual
ERROR CODES
The following is a partial list of possible error codes for the Power Wave AC/DC 1000. For a complete listing con-
sult the Service Manual for this machine.
Error Code #
31 Primary (Input) overcurrent error.
32 Capacitor "A" under voltage (Left
side facing machine)
33 Capacitor "B" under voltage (Right
side facing machine)
34 Capacitor "A" over voltage (Left
side facing machine)
35 Capacitor "B" over voltage (Right
side facing machine)
36 Thermal error
37 Soft start error
41 Secondary (Output) overcurrent error
43 Capacitor delta error
46 Secondary (Output) overcurrent error
49 Single phase error
54 Secondary (Output) overcurrent error
Other
Indication
Excessive Primary current present. May be related to a switch board or output
rectifier failure.
Low voltage on the main capacitors. May be caused by improper input configu-
ration, or an open/short circuit in the primary side of the machine.
Excess voltage on the main capacitors. May be caused by improper input con-
figuration, , excessive line voltage, or improper capacitor balance (see Error
43)
Indicates over temperature. Usually accompanied by Thermal LED. Check fan
operation. Be sure process does not exceed duty cycle limit of the machine.
Capacitor pre-charge failed. Usually accompanied by codes 32-35.
The long term average secondary (weld) current limit has been exceeded.
This error will cause the machine output to phase back to 100 amps, typi-
cally resulting in a condition referred to as “noodle welding”.
NOTE: The long term average secondary current limit is 1050 amps.
The maximum voltage difference between the main capacitors 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).
Absolute maximum output level has been exceeded. Usually associated with
excessive short circuit currents and/or specific weld mode issues. This is a
short term average designed to protect the inverter switching circuitry.
Indicates machine is running on single phase input power. Usually caused by
the loss of the middle leg of the input power (L2).
The long term average secondary (weld) current limit has been exceeded.
This error will immediately turn off the machine output.
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.
