WARNING
Use ONLY the torch supplied with this machine. For a
replacement refer to the Maintenance section of this
manual.
WARNING
Always turn OFF the machine when working on the
torch.
WARNING
Do not remove the work clamp during cutting, plasma
cutting generates high voltages that can kill.

information refer to the Technical Specification section.
This machine is sent from the factory with a cutting torch
and work clamp installed. The work clamp must be
securely connected to the work piece. If the work piece
is painted or extremely dirty it may be necessary to
expose the bare metal in order to make a good electrical
connection.
Built-In Compressor
This machine has a built-in compressor that allow to
operates in areas where an external primary air is not
available. Only an electrical mains supply is necessary!
Controls and Operational Features
INVERTEC PC208 front command panel.
The PC208 machine front panel has a lower quantity of
commands than the PC210 showed below, but the
displacement is the same:
The commands [A], [B], [C], [D] are available on the
PC208 front panel.
The commands [E], [F] aren’t available on the
PC208 front panel.
INVERTEC PC210 front command panel.
Commands descriptions:
A. Output Current Knob: Potentiometer used to set the
output current used during cutting. Refer to the
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.

Part in place error: the retaining cap
is not properly screwed.
To restore the machine:
Screw firmly the torch retaining
cap.
Wait for 5seconds; during this
time the Output and Thermal
LEDs blinks alternately.
After 5seconds the machine is
automatically restored and
ready to operate.
Off
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.
Off
Blink
Mains undervoltage or overvoltage
error: the machine is disabled.
When the mains return in the
correct range, the machine restart
automatically.

Off
Low air pressure error.
To check / adjust the air pressure
(see recommended values in the
Tecnical Specifications of this
manual):
Put the machine in Purge mode
[A].
Check and adjust the air
pressure through the
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. With the “Ext Air”
position 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.
