MACHINE ON Should always be on when machine is on. Normal
OUTPUT ON On when there is voltage potential at the Normal

If OUTPUT ON is blinking alternately
with FAULT, the pilot arc duty cycle is
exceeded. Wait for machine lights to stop blinking.
AIR PRESSURE On whenever the air pressure is above 60 Normal conditions are purge, preflow,
psi (413 kPa), there is an error condition postflow and cutting.

The air will turn on for a brief time when
power is first applied to machine.
THERMAL Should normally be off. If on, wait for machine to cool down.
