PRO-CUT 60 STATUS LIGHTS OPERATING MODES

STATUS
LIGHTS
MACHINE ON Should always be on when machine is on. Normal
OUTPUT ON On when there is voltage potential at the
torch (cutting or pilot).
OUTPUT ON is blinking alternately with
AIR PRESSURE when power is first
applied to machine.
If OUTPUT ON is blinking alternately
with FAULT, the pilot arc duty cycle is
exceeded.
AIR PRESSURE On whenever the air pressure is above 60 Normal conditions are purge, preflow,
psi (413 kPa), there is an error condition
mentioned above where air will turn on.
The air will turn on for a brief time when
power is first applied to machine.
THERMAL Should normally be off.
FAULT Light on. At end of preflow, machine
checks to see if the torch is shorted and if Check torch cable to see if it is punctured
it can fire the transistors.
Light blinking. If cutting tried with air
pressure less than 60 psi (413 kPa) while
air is flowing, the machine will wait for air
pressure to become greater than 60 psi
(413 kPa).
Light blinking alternately with OUTPUT
ON.
Light started blinking during cutting or
gouging. There is an overcurrent condition 1/8" (3.2mm) at high range of machine and
caused by a surge of current the machine nozzle is accidentally touched to work, shorten
was not designed to handle. Release the
trigger and resume cutting or gouging.
Light blinking with THERMAL light on.

No air connected to machine, air pressure
