Error codes for the
Invertec V450
-
PRO
The following is a list of possible error codes that the Power Wave can output via the status light
Error Code #
Indication
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 Softwa
re.
31 Primary overcurrent error.
Excessive Primary current present. May be related to a
switch board or output rectifier failure.
32 Capacitor “A” under voltage
(Left side facing machine)
33
Capacitor “B” under voltage
(Right side facing machine)
Low voltage on the main capacitors. May be caused by
imp
roper input configuration, or an open/short circuit
in the primary side of the machine.
34
Capacitor “A” over voltage
(Left side facing machine)
35
Capacitor “B” over voltage
(Right side facing machine)
Excess voltage on the main capacitors. May be caused
by
improper input configuration, or an open/short
circuit in the primary side of the machine.
36 Thermal error
Indicates over temperature. Usuallyaccompanied by
Thermal LED. Check fan operation.
Be sure process
does not exceed duty cycle limit of the machine.
37 Softstart error
Capacitor precharge failed. Usually accompanied by
codes 32
-
35.
41 Secondary overcurrent error
The secondary (weld) current limit has been exceeded.
When this occ
urs the machine output will phase back
to 100 amps, typically resulting in acondition refered
to as “noodle welding”
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).
