4.1 Cutting Preparation
4.2.1 Tightly connect the power cable to an electrical socket outlet ( refer to the Input
Voltage in section 2 Technology Parameters).
4.2.2 Connect the air pipe to the air supply equipment and the earth cable to the
workpiece.
4.2.3 Turn on the power switch, the power source lamp is lit.
4.2.4 Turn the RUN/SET switch to SET position – the air flows, Regulate the air
pressure to 3.5-6.0 bar
4.2.5 Turn the RUN/SET switch to RUN position. Regulate the current after the flow
stops.
4.2.6 Preparation is complete.
NOTE (1) The alarm lamp is on when cutting. Switch off the torch until the alarm
sounds, then press the switch again to restart cutting.
(2) During automatic gas test and examination, press on the cutting torch.
(3) After long use, the surface of the electrode and nozzle will have an oxidation
reaction. Replace the electrode and nozzle. The alarm lamp will light when
you remove the shield cup as a safety precaution.
(4) If the cutting current is higher than 40A when the tip touches the work-
piece, the current will reduce to 40A in order to protect the tip.
(5) During post gas, if you hold down the trigger for a long time the arc restarts,
if you press and loosen the trigger quickly the gas stops, you can then hold
down the trigger to restart the machine.

4.2 Cutting Preparation
1)
Tightly connect the power cable to electrical socket outlet (the input voltage, refer to the section 2
technology parameters)
2)
Tonnect the air pipe to the air supply equipment, the earth cable to the workpiece
3)
Turn on the power switch ,the power source lamp on.
4)
Turn the RUN/SET switch to SET position, the air flow, then regulate the air pressure to 3.5-6bar
5)
Turn the RUN/SET switch to RUN position, regulate the current after the flow stops.
6)
Now all the preparation done .
