ERROR CODES FOR THE POWER WAVE ®
The following is a partial list of possible error codes for the Power Wave ® AC/DC 1000 ® SD. For a complete listing
consult the Service Manual for this machine.
Error Code #
31 Primary (Input) overcurrent error.
32 Capacitor “A” under voltage
(right side facing the Switch PC Board)
33 Capacitor bank "B" under voltage
(left side facing the Switch PC Board)
34 Capacitor "A" over voltage
(right side facing the Switch PC Board)
35 Capacitor "B" over voltage
(left side facing the Switch PC Board)
36 Thermal error
37 Softstart (pre-charge) error
39 Misc. hardware fault
43 Capacitor delta 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 configuration, or an open/short circuit in the
primary side of the machine.
Excess voltage on the main capacitors. May be caused by
improper 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. Also acts with
a malfunction.
Capacitor precharge failed. Usually accompanied by
codes 32 and 33.
Unknown glitch has occurred on the fault interrupt circuit-
ry. Sometimes caused by primary over current fault, or
intermittent connections in the thermostat circuit.
The maximum voltage difference between the main capac-
itors 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).
A complete list of error codes is available in Weld
Manager under Tools -> Lookup Error (available at
www.powerwavesoftware.com).
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
