WARNING
The beam path must always be closed, also if there is no product in front of the
laser lens.
1.
Normal operation does not include service, maintenance nor repairs.
The Laser Source
As laser beam source (hereinafter called laser) a CO
2
laser in continuous wave
operation is used. The laser itself is classified as class 4. It produces invisible (in-
frared) radiation which is extremely dangerous for the eye and dangerous for the
skin.
The laser can be modulated with a frequency between 50 Hz and 20/25/160 kHz
(10/30/60 W). The actual frequency depends on the application.
The following values can be reached (no specification):

WARNING
As soon as the closed shielding or the housing of the laser are opened anywhere
the complete laser system is set to class 4.
In that case appropriate measures have to be taken in order to protect people
working in the laser area against excessive radiation! For information on appropri-
ate safety measures we offer special training seminars, see also section »Mainte-
nance and Service«.
CAUTION
... with modifications!
EN 60825, part 1, »Radiation safety of laser systems«, section 4.1.1 says:
If a modification by the user to a laser system previously classified in accordance
with this standard leads to a change of its performance data and/or its intended
use that person or organization performing the modification is responsible for a
new classification and labeling of the laser system.
WARNING
The pilot laser can be used for simulation or adjustment without the CO
2
laser. Al-
so in this case you must wear laser safety goggles for protection against CO
2
la-
ser radiation.
