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
chopper has errors. If cycling the input power on the machine does
not clear the error, contact the Service Department.

machine does not clear the error, contact the Service Department.
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.
Long term average motor current limit has been exceeded.
Typically indicates mechanical overload of system. If problem con-
tinues consider 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.
