Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
CAUTION
ERROR CODES FOR THE POWER WAVE ® S700
The following is a list of possible error codes that the Power Wave ® S700 can output via the status light (see
“Troubleshooting the Power Wave ® System Using the Status LED”).
Error Code #
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 Softstart error
41 Secondary overcurrent error
43 Capacitor delta error
49 Single phase 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 weld 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”.
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).
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, contact the Service Department.
