Parkside PPS 40 A1, Operation And Safety Notes

14 GB
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 two types
of channels. These channels
generate a constant flow of
protective gas around the cutting
area. The pressure of the gas
flow 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 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 distance of at least 0.5 m all around.
„
Ventilation slots must not be blocked
or covered.
„
The device must not be used as 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.
• Connecting compressed air
PLEASE NOTE!
f
This device is designed for operating
pressure of up to 6.3 bar. Please bear
in mind that the pressure can lower
while setting the air pressure.
Thus, in a hose length measuring
10 m and an internal diameter of 9 mm
it drops by approx. 0.6 bar.
The compressed air must be filtered,
lubricated and regulated.
„
Connect the compressed air hose 16 on
the back of the plasma cutter 1 to the
compressed air connection 20 . To do so,
insert the side of the compressed air hose
16 into the compressed air connection 20
of the plasma cutter 1 without a quick
connector.
„
The pressure can be set via the knob 21
on the condensate separator. (see Fig. J - L)
