Safety
If a main laser beam comes into contact with inflammable material, e.g. paper, the latter may ignite, quickly
leading to fire. Therefore, before switching on the laser and after deactivating the Standby-mode you must
make sure that there is no inflammable material in the path of the laser beam.
Furthermore, gases formed beneath the material being processed may ignite, especially if the extraction
requirements are not met.
The risk of flaming is increased in case of insufficient care and cleaning as well.
Additionally, regularly control the air cooling system on your laser. In particular, the filters and ventilators
should be checked regularly for proper function to avoid defects caused by overheating.
2.9.2 Gases, fumes and dust
Depending on the materials being processed and the parameters selected, laser processing may generate
gases, fumes, aerosols or dust. Depending on the material, such by-products may be toxic. In individual
cases, the reaction products may be electrically conductive dusts. If these enter electric systems, short-
circuiting with personal injury and property damage may occur.
The operator is responsible for ensuring presence of a suitable extraction system and compliance with the
relevant guidelines in order to protect persons and the environment. The guideline VDI 2262 1-3 "Workplace
air" provides, among other things, additional remarks.
The operator must also ensure that gases, fumes or dust do not settle on the processing lens. Any dirt
accumulating on the processing lens can lead to loss of performance, poor processing results and damage
to the device.
2.9.3 Reflection through materials
Warning
Danger from laser beam.
Invisible laser radiation of reflecting materials can cause serious injury or material damage.
– Only material according to the intended use of the machine may be used.
– Do not use material with high reflecting surfaces such as aluminum, chromium, precious
metals, metal foils, stainless steel, brass, copper and titanium.
– Take special care with surfaces formed convex and concave.
– Do not leave or put objects on the work surface/working area.
