General Plasma Explanations - Parkside PPS 40 A1 Bedienungs- Und Sicherheitshinweise

with a plasma cutter with class A
electromagnetic compatibility.
Thus, it meets the appropriate
requirements in the industrial and
residential area. In residential
areas, it can be connected to
the public low-voltage supply
network.
Even if the plasma cutter complies
with the emission level as per the
standard, the plasma cutter can
still result in electromagnetic
disturbances in sensitive systems
and devices.
The operator is responsible for
malfunctions that occur through
the arc while welding and must
take suitable protective measures.
In doing so, the operator must
consider the following:
Power cables, control, signal
„
and telecommunication lines
Computer and other
„
microprocessor controlled
devices.
Television, radio and other
„
playback devices
Electronic and electrical safety
„
equipment
Persons with cardiac
„
pacemakers or hearing aids
Measurement and calibration
„
devices
Noise immunity of other
„
Safety instructions / General plasma explanations
devices in the vicinity
The time of day at which the
„
welding work is performed.
The following is recommended
to reduce possible interference
radiation:
The plasma cutter must be
„
regularly maintained and kept
in a good condition
Welding cables should be
„
completely unwound and
installed parallel on the floor,
if possible
Devices and systems at risk
„
of interference radiation must
be removed from the welding
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 controls the speed
at which the plasma can rotate.
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.
