TROUBLESHOOTING & REPAIR
USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
The Power Wave / Power Feed are best diagnosed as
a system. Each component (power source, user
interface, 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 sys-
tem, 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 trou-
bleshooting charts for both machine and weld perfor-
mance.
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 355/405 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.
LIGHT CONDITION INDICATION
Status LED is solid green (no blinking)
1. System OK. Power source communicating nor-
mally with wire feeder and its components.
Status LED is blinking green
2. Occurs during a reset, and indicates the
POWER WAVE 355/405 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 opera-
tion.
Status LED is blinking red.
Not applicable
Status LED is solid red (no blinking).
Non-recoverable hardware fault. Generally indi-
cates nothing is connected to the POWER
WAVE 355/405 wire feeder receptacle. See
Trouble Shooting Section.
Status LED is blinking red and green
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
355/405. 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. The codes will be
separated by a green light. There may be more
than one error code indicated.
To clear the error, turn power source off, and
back on to reset.
