Connect the gas supply to C fitting making sure that the
equipment can supply adequate capacity and pressure to
the torch being used.
If the air is supplied from a compressed air cylinder, the
cylinder must be equipped with a pressure regulator;
never connect a compressed air cylinder to the ma -
chine reducer direct. Pressure may be higher than the
reducer capacity with consequent possible explosion
Connect the power cord A : the yellow-green cable wire
must be connected to an efficient system grounding
socket; the remaining wires must be connected to the
power supply line by means of a switch placed as close
as possible to the cutting area, to allow it to be quickly
shut off in case of emergency.
The capacity of the switch or fuses installed in series with
the switch must be equal to I1eff current drawn by the
device.
The current I1eff max absorbed is determined by reading
the technical data shown on the unit in correspondence
of the available supply voltage U1.
Any extension cords must be sized appropriately for the
absorbed current I1eff max.
4. USE
When the plasma cutting machine is switched on, by tur-
ning the knob
B , the display N shows:

- The current firmware version installed in the control board ;
- The torch type mounted (CP 70C MAR/DAR; CP 162C MAR/

- The length of the assembled torch (6/15m)
Note: The type and length of the torch are automatically
recognized.

In general, with the
H
knob you select different items such
as:
- Working mode CUT, SELF RESTART,
and GOUGE (only for CP 162C torch);
- Working current;
- work pressure;
- Cutting gas;
- material
By briefly pressing the H knob on the single selected task,
it becomes bold and can be modified.
4.1 CUTTING (“CUT” OPERATING MODE)
CUT
110 A
MILD STEEL
Ø 1.50
Air 5.5 bar CP162C
Choose the type of material to be cut (Mild Steel, Stain-
less Steel or aluminum) and the cutting gas (air or nitro-
gen N2).
Then adjust the cutting current depending on:
- the type of the chosen material and the thickness to be
cut;
- the gas used
following directions shown in the cutting tables.
During the current regulation, the display
N shows the
correct nozzle diameter to be used.
Now you can set the correct operating pressure by se-
lecting the correspondent task and pressing the knob
H :
now the gas comes out of the torch.
CUT
110 A
MILD STEEL
Ø 1.50
Air 5.5 bar
Turn now the knob D of the pressure reducer.
The correct working pressure is signaled by central leds,
beside the set value. If pressure is too low or, conversely,
too high, these are highlighted by the flashing LEDs, re -
spectively the left or the right.
When pressure is adjusted, lock the knob
D by pushing
it down.
Cutting speeds can be read on display
N in function of
the thickness, the material and the fixed current.
In particular, by selecting the material and pressing down
the
H knob, you will see the following screen shot:
