General Plasma Explanations; Before Use; Installation Environment - Parkside PPS 40 C3 Operation And Safety Notes Translation Of The Original Instructions

The following is recommended
to reduce possible interference
radiation:
„
the plasma cutter must be
regularly maintained and kept
in good condition.
„
cutting cables should be com-
pletely unwound and installed
parallel on the floor, if possible
„
devices and systems at risk of
interference radiation must be
removed from the cutting area
if possible, or shielded.
• 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 flows 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 flow of
shielding gas around the cutting
area. The pressure of the gas
flow controls the radius of the
plasma jet.
PLEASE NOTE!
fThis machine is only designed to use
compressed air as "gas".

• Before use

• Installation environment

Make sure that the working area is
sufficiently ventilated. If the device is used
without sufficient 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
gap of at least 0.5 m all around.
„
Ventilation slots must not be blocked or
covered.
