z Protection against rays
and burns
Warn of the danger to the
eyes by hanging up a sign
saying "Caution! Do not look
into flames!". The workplaces
must be shielded so that the
persons in the vicinity are
protected. Unauthorised
persons must be kept away
from cutting work.
The walls in the immediate
vicinity of fixed workplaces
should neither be bright
coloured or shiny. Windows
up to head height must be
protected to prevent rays
being transmitted or reflecting
through them, e.g. by using
suitable paint.
z EMC Device Classification
According to standard
IEC 60974-10, it has to do 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 plasma cutting
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 micro-
processor 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
devices in the vicinity
The time of day at which the
cutting 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
