TROUBLESHOOT SYSTEM PROBLEMS
The Status LED on the power source case front
can help diagnose problems down to the system
component (power source, wire feeder, wire drive,
etc.) level. If, for any reason, the system does not
appear to be working properly, always check the color of the Status LED, and refer to the following
chart to help you determine which system compo-
nent (power source, wire feeder, wire drive, etc.)
may be faulty. Replace the components identified
as potentially faulty with known good components,
and the system should operate normally.

with wire feeder or its components. Turn machine
