Commands descriptions:
A.
Output Current Knob: Potentiometer used to set the
output current used during cutting.
Technical Specification section for more information
about the machine rated current range.
Air Purge:
The Output Current Knob completely
rotated counterclockwise enables the air purge
function.
A 5 minutes timeout stops the purge
function; this happens only if the Output Current Knob
remains in the purge mode for a long time.
B.
Power ON/OFF green LED: It lights up when the
machine is ON.
C. Output red LED:
See meanings in the following
table.
D. Thermal yellow LED: See meanings in the following
table.

On
The machine is overheated and
the output has been disabled.
This usually occurs when the duty
cycle of the machine has been
exceeded. Leave the machine On
to allow the internal components to
cool. When the thermal LED turns
off, normal operation is again
possible.

Mains undervoltage or overvoltage
error:
When the mains return in the
correct range, the machine restart
automatically.

Wait for 5seconds; during this
time the Output and Thermal

the machine is disabled.
Put the machine in Purge
mode [A].
Check and adjust the air
pressure
through
manometer and air pressure
regulator knob [F].
If necessary, check and adjust
also the inlet air pressure
through the commands of the
external compressor.
E.
Internal / External air selection (PC210 only): This
switch determine the air supply. With the "In Compr"
position selected, the machine operates through the
built-in compressor.
selected, the internal compressor is completely
disabled and the machine operates through an
external air supply hose connected to the proper air
inlet connection placed on the machine rear side.
PC210 Only: If operate with external air, be sure to
select the "Ext Air" switch position in order to
completely
Otherwise the compressor may be damaged by the
probable greater pressure of the external air.
F.
Air Pressure Gauge and Regulator Knob (PC210
only):
Allow to regulate and monitoring the air
pressure.
G. Fan: Provides machine cooling. It is switched ON
with the machine and continues to run till the machine
is turned OFF.
H. Power Switch: It turns ON / OFF the input power to
and
the machine.
I.
Input cable: Connect it to the mains.
J.
Air Inlet (PC210 only): If the "Ext Air" operating mode
is selected, connect here the hose carrying the air to
the machine.
A clean, dry air must be supplied to the machine.
pressure setting above 7.5bar could damage the torch.
Failure to observe these precautions could result in
excessive operating temperatures or damage to the torch.
Cutting Process
The air plasma cutting process uses air as primary cutting
gas and as torch cooling gas.
PC208 – PC210:
compressor with a pressure of 3.5bar (approximate
value).
The PC210 can reach the best cutting performances
operates also with external air; in this case the air
the
pressure is limited by a pressure regulator [F], set at
factory at 5.0bar. In case to adjust the air pressure, put
the machine in Purge mode [A].
The pilot arc is struck as follow:
PC208:
The torch button enables the built-in compressor that
provide the air flow to the torch. Releasing the torch
button the cutting process is stopped, but the
compressor continues to run for the post-flow stage.
