impedance is equal to or

If you are in any doubt, then
please contact an electrical
professional.
• General plasma
explanations
Plasma cutters are operated by
pushing pressurised gas, e.g.
air, through a small pipe. In the
centre of the pipe, there is a
negatively charged electrode that
is directly above the nozzle. The
vortex ring causes the plasma to
rotate quickly. If you supply the
negative electrode with current
and make the tip of the nozzle
touch the metal, this connection
creates a closed, electrical circuit.
A powerful spark occurs between
the electrode and the metal.
While the gas fl ows into the
pipe, the spark heats up the gas
until it has reached the plasma
condition. This reaction causes
a current from the controlled
plasma with a temperature of
16,649 ºC or more that moves at
speed of 6.096 m/sec and the
metal transforms into steam and
molten discharge. The plasma
itself conducts electrical current.
The working circuit that allows
the arc to occur remains as long
as current is supplied to the
electrode and the plasma remains
in contact with the metal to be
processed.
The cutting nozzle has a
range of further channels.
These channels generate a
constant fl ow of protective gas
around the cutting area. The
pressure of the gas fl ow controls
the radius of the plasma jet.
PLEASE NOTE!

This machine is only designed to use
compressed air as “gas”.
• Before use
• Installation environment
Make sure that working area is suffi ciently
ventilated. If the device is used without
suffi cient cooling, the power-on time reduces
and it can result in overheating.
Additional protection can be required for this
purpose:

The device must be free-standing with a
distance of at least 0.5 m all around.

Ventilation slots must not be blocked or
covered.

The device must not be used a storage
place and tools or other items must not
be placed on the device.

It must be operated in a dry and well
ventilated working environment.
