(Output LED off)

Thermal overload 
(Thermal LED on)

1. No Input Voltage.

2. Faulty supply plug or cable.

3. Internal fuse blown.

1. Input  voltage  out  of  range  (less

than 95 or greater than 265VAC).

2. Input current too high due to oper-

ating beyond rated duty cycle.

1. While  in TIG  mode, Trigger  circuit

not mode at 6 pin amphenol.

1. Unit has been operated beyond its

capacity rating.

2. Airflow through machine is restrict-

ed or fan has failed.

If all recommended possible areas of
