POWER WAVE 455
Observe all Safety Guidelines detailed throughout this manual
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
ERROR CODES FOR THE POWERWAVE
The following is a list of possible error codes that the Power Wave 455 can output via the status light (see
"Troubleshooting the Power Wave / Power Feed System Using the Status LED." If connected to a PF-10/11
these error codes will generally be accompanied by an "Err 006" or "Err 100" on the user interface display.
Error Code #
11 CAN communication bus off.
12 User Interface time out error.
21 Unprogrammed Weld Mode.
22 Empty Weld Table.
23 Weld Table checksum error.
31 Primary 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 overcurrent error
43 Capacitor delta error
49 Single phase error
Other
Indication
Probably due to excessive number of communication errors.
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.

Welding Software.

Welding Software.
Excessive Primary current present. May be related to a short in the
main transformer or output rectifier.
Low voltage on the main capacitors. May be caused by improper
input configuration, or an open/short circuit in the primary side of
the machine.
Excess voltage on the main capacitors. May be caused by improp-
er input configuration, 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 precharge failed. May be accompanied by codes 32-35.
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 refered to as "noodle welding"
NOTE: The maximum secondary limit is 570 amps for the standard
stud (500 amps for CE models), and 325 amps for the STT stud
and all single phase operation.
The maximum voltage difference between the main capacitors has
been exceeded. May be caused by an open or short in the primary
or secondary circuit(s).
Indicates machine is running on single phase input power. Usually
caused by the loss of the middle leg (L2).
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, try reloading the operating system. If this
fails, replace the control board.
