POWER WAVE 405
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 405 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
33 Capacitor "B" under voltage
34 Capacitor "A" over voltage
35 Capacitor "B" over voltage
36 Thermal error
37 Softstart error
41 Secondary overcurrent error
43 Capacitor delta 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.

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.
When accompanied by an overvoltage error on the same side, it
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.
Excess voltage on the main capacitors. May be caused by improp-
er input configuration.
When accompanied by an under voltage error on the same side, it
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.
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. Usually 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 referred to as "noodle welding"
NOTE: The secondary limit is 570 amps for the standard stud, and
325 amps for all single phase operation.
The maximum voltage difference between the main capacitors has
been exceeded. May be accompanied by errors 32-35.
Error codes that contain three or four digits are defined as fatal
errors. These codes generally indicate internal errors on the
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.
