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.
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 F355i 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.
