PRECESSION ELEPHANT 2 Scan Head 2
•
Be sure, that an adequate working exhaust ventilation system is connected to
the material processing laser, that the exhaust ventilation tube is not damaged
or plugged, and that the whole exhaust ventilation passage is open
•
Be sure, that the exhausting volume flow is adequate. A very low exhausting
volume flow, an obstructed exhaust ventilation tube or an obstructed exhausting
nozzle can caused a very dirty laser processing area covered with laser generated
dust and particles
•
Be sure, that the dust filters of the exhaust ventilation system are suitable for the
laser material processing. If other materials will be processed by the laser than
those intended, ensure that the incorporated filters are suitable for the LGAC of
these materials
•
Exchanging of dust filters or exhaust ventilation tubes of an exhaust ventilation
system has only to be done with suitable respiratory protection, eye protection
glasses and protection gloves. Raised dust or fume must not be inhaled and must
not get in contact with the human skin
•
Exchanged dust filters or exhaust ventilation tubes have to be professionally
disposed as hazardous waste, if required
•
If the laser processing area with the incorporated components like focusing
optics, exhausting nozzles and work piece holders should be cleaned, suitable
personal protection devices have to be worn, such as respiratory protection, eye
protection glasses and protection gloves. Raised dust or fume must not be
inhaled and must not get in contact with the human skin
•
If you notice or smell any kind of LGAC probably coming from the material
processing laser, you have to immediately switch off the laser system and check
the correct function of the exhaust ventilation system and the whole exhaust
ventilation passage. If required, exchange the dust filters and clean the laser
processing area. The working area around the material processing laser should
be well ventilated before starting the laser again
•
All personnel operating the material processing laser has to be instructed about
the hazards with LGAC and the required safety measures
2.4.2 Laser radiation
During commissioning it is necessary to adjust the laser beam to the scan head and to
observe the laser beam.
