The air plasma cutting process uses air as primary
cutting gas and as torch cooling gas. The air circuit
includes a pressure regulator set at 5,5bar.
The pilot arc is initiated by pressing the trigger,
which activates the solenoid, the air pushes back
the electrode inside the torch and light the pilot arc.
A clean, dry air or nitrogen must be supplied to the
machine. A pressure setting above 7,5bar
could
damage the torch. Failure

The design concept at the basis of these power sources
is to have available a current which remains constant at
the set value, independently from the length of the
plasma arc.

Connect the torch [J] and the work cable [K].

Turn ON the Power Switch [L] placed on the back of
the machine; the LED [C] on the front panel will turn
ON. One second after the switching ON a "click"
from the starter relay will be heard; the unit is now
ready to operate.

The working pressure should be set at 5,5 bar.

Set the desired current value with the Output
Current [A] knob.
To start the cutting process just press the torch button,
making sure you are not aiming the torch air blow
towards people or foreign objects. During the cutting
process it is possible to hold the torch away from the
work piece for an extended period of time.

Avoid to touch the work piece directly with the torch,
when you do not have the torch with the proper
nozzles.

The arc length should not be more than 6-7mm.
Once the cutting process is terminated releasing off the
torch button will cause the plasma arc to be turned off;
the air flow will continue for approximately 30sec. (post-
flow) to allow the cooling down of the torch.
