R450 errors will be displayed on the
user interface (if it is installed). There are two status lights that
display error codes. If a problem occurs it is important to note the
condition of the status lights. Therefore, prior to cycling power to
the system, check the power source status light for error
sequences as noted below.
There is one externally mounted status light located on the case
front of the machine. This status light corresponds to the main
control board and input control board’s status.
Included in this section is information about the Status Lights and
some basic troubleshooting charts for both machine and weld
performance.
The status light for the main control board and input control board
are dual-color LED’s. Normal operation for each is steady green.
Error conditions are indicated in the following chart Table E.1.

R450 is mapping (identifying) each component in
the system. Normal for first 1-10 seconds after power is turned on, or if the system configuration is changed during operation.

Non-recoverable system fault. If the Status lights are flashing any combination of red and green, errors are present.
Read the
error code(s) before the machine is turned off.
Error Code interpretation
through the Status light is detailed in the Service Manual. Individual code digits are flashed in
red with a long pause between digits. If more than one code is present, the codes will be separated by a green light. Only active
error conditions will be accessible through the Status Light.
Error codes can also be retrieved with the
Power Wave Manager Utility
available at
www.powerwavesoftware.com
). This is the preferred method, since it can access historical information contained in the
error logs.
To clear the active error(s), turn power source off, and back on to reset.
