USING THE STATUS LED TO 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 compo- nents, and the system should operate normally.

Status LED is solid green (no blinking).
