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

persons in the vicinity are
protected. Unauthorised
persons must be kept away
from cutting work.
The walls in the immediate vicin-
ity 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 the standard
IEC 60974-10, this is a plasma
cutter in electromagnetic compat-
ibility Class A. Class A devices
are devices that are suitable for
use in all other areas except
residential areas and areas that
are directly connected to a low-
voltage supply mains that (also)
supplies residential buildings.
Class A devices must adhere to
the Class A limit values.

WARNING NOTICE: Class A
devices are intended for use in
an industrial environment. Due to
the power-related as well as the
radiated interference variables,
difficulties might arise in ensuring
electromagnetic compatibility in
other environments.
Even if the device complies
with the emission limit values in
accordance with the standard,
such devices can still cause
electromagnetic interference in
sensitive systems and devices.
The user is responsible for faults
caused by the arc while working,
and the user 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
