ERROR CODES FOR THE POWER WAVE® C300
Indicates over temperature. Usually accompanied by Thermal LED.
Check fan operation. Be sure process does not exceed duty cycle
limit of the machine
The long term average secondary (weld) current limit has been
exceeded. NOTE: The long term average secondary current limit is
325 amps.
Indicates communication link between main control board and chop-
per has errors. If cycling the input power on the machine does not
clear the error, contact the Service Department.
Review error code from input board status light or status beeper.
Most likely caused by an over power condition which caused an

machine does not clear the error, contact the Service Department.
Error codes that contain 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.
Wire Drive MoDule
Long term average motor current limit has been exceeded. Typically
indicates mechanical overload of system. If problem continues con-
sider higher torque gear ratio (lower speed range).
Absolute maximum motor current level has been exceeded. This is
a short term average to protect drive circuitry.
