USING THE STATUS LED TO
TROUBLESHOOT SYSTEM
PROBLEMS
The Power Wave / Power Feed are best diagnosed as
a system. Each component (power source, user inter-
face, and feed head) has a status light, and when a
problem occurs it is important to note the condition of
each. In addition, errors displayed on the user interface
in most cases indicate only that a problem exists in the
power source, not what the problem may be.
Therefore, prior to cycling power to the system,
check the power source status light for error
sequences as noted below. This is especially
important if the user interface displays "Err 006" or
"Err 100" .
Included in this section is information about the power
source Status LED, and some basic troubleshooting
charts for both machine and weld performance.
The STATUS LIGHT is a two color light that indicates
system errors. Normal operation is a steady green
light. Error conditions are indicated in the following
chart.
NOTE: The Power Wave status light will flash green,
and sometimes red and green, for up to one minute
when the machine is first turned on. This is a normal
situation as the machine goes through a self test at
power up.

MEANING
1. System OK. Power source communicating normally
with wire feeder and its components.
2. Occurs during a reset, and indicates the Power
Wave 455M (CE) is mapping (identifying) each com-
ponent in the system. Normal for first 1-10 seconds
after power is turned on, or if the system configura-
tion is changed during operation.
3. Non-recoverable system fault. If the PS Status light
is flashing any combination of red and green, errors
are present in the Power Wave 455M (CE). Read
the error code 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.
To clear the error, turn power source off, and back on
to reset.
