1. Make sure there is at least 80 psi connected to the gas connec-
tion at the back of the machine.
2. Turn the output knob to the purge zone and set the regulator to
the correct pressure. The pressure may increase when air stops
flowing but this is normal. Do not reset the pressure while the air
is OFF.
3. Possible faulty Pressure Switch.
4. Possible faulty Control board.
1. Verify Torch consumables are in good condition and properly
installed. If torch and consumables are properly installed, the
Yellow LED should turn off. The unit may be required to have the
input power turned off then back on. Normal cutting or gouging
can resume.
1. The machine's thermostat has tripped due to exceeded duty cycle
limits. Do NOT turn the power off. Allow the machine to cool for
15 - 30 minutes and the thermostat will reset itself.
2. The machine's air louvers or fans are obstructed such that air
cannot flow to properly cool the machine. Remove any foreign
material that may block air flow. Blow the machine out with a
clean, dry air stream.
3. Possible faulty Control board.
