1. Safety is essential Chapter safety For your safety This chapter contains important hints for a safe operation of the laser product. Read the hints carefully before putting the laser product into operation. This chapter summarizes information that the operator must know to ensure a safe operation of the laser device. Information on the following factors is indicated: ■ ■ ■ Hazards and warning hints Hazards that may arise from the laser product.
2. Warning instructions A warning instruction is information that: ■ ■ ■ Names the type and source of a danger. Indicates possible consequences in case the danger is not avoided. Gives instructions for how to avoid any damage. One of the signal words "Danger", "Warning", "Caution", or "Attention" indicates the severity of the possible consequences in case the instructions are not observed. "Danger" warns against a great danger. If not avoided, it leads to death or serious injuries.
3. Laser product Terms Laser products include devices, systems or components used for generating, transmitting and using laser light. TRUMPF products summarized under the term "laser product" include: ■ ■ ■ ■ ■ ■ Laser light Lasers (beam sources) Laser machines Laser workstations Laser devices Laser light cables Focusing optics Laser light is electromagnetic radiation with wavelengths from 100 nm to 1 mm produced as the result of controlled stimulated emission.
Laser device Laser devices include all components required for generating laser light. Laser device components include: ■ ■ ■ ■ Laser with pump source Energy supply for the pump source, e.g.
Laser beam guidance Safety circuit The laser beam guidance deflects the output radiation of the laser to the workpiece. A safety circuit is an electric circuit for monitoring protective covers and doors of laser protective casings and cabins. When the contacts are looped in, the safety circuit should always be closed when all monitored covers and doors are closed. When a contact interrupts the safety circuit because a door is opened, for example, laser light emission is immediately stopped.
4. Hazards The laser product has been built in accordance with state-of-theart standards and the recognized safety rules. However, it might cause hazards for persons or material property during use. If you do not observe the accident prevention regulations, these hazards may result in damage. The following overview indicates the possible hazards that might be caused by your laser product. ■ ■ It indicates how TRUMPF has reduced the risk by applying constructive measures.
Class 3 Class 3 is subdivided into class 3R and class 3B acc. to EN 60825-1. A previously existing restriction of class 3 to certain spectral ranges no longer exists. Class 3R laser products exceed the limits of class 2. In most cases the risk is low. The risk of injury increases with the time of exposure. A deliberate irradiation of your eyes is dangerous. Class 3B laser products are normally dangerous when you look directly into the beam. The observation of diffuse reflections is usually not dangerous.
Regularly check the function and the operation safety of the exhauster and ensure a sufficient ventilation in the room. When recirculating the exhausted air into the room, ensure that the rest quantities of harmful substances are below the admissible limit values. Inform persons staying in the room on risks and instruct them in danger-conscious behavior. 4.3 Thermal energy Fire, explosion Class 3B or 4 laser light may cause fires if it ignites inflammable material.
Hot surfaces on the bottom side of the focusing optics may burn your skin. CAUTION Ø Ø Avoid contact with hot surfaces. Let the focusing optics cool down before carrying out maintenance or cleaning work. 4.4 Focusing optics Noise The use of focusing optics in conjunction with lasers and assist gas produces noise. Sources of noise in the area of the focusing optics include: ■ ■ ■ Material that evaporates as a result of the exposure to laser light.
5. Safety of the laser product 5.1 Laser beam emission openings The following pictures show examples of focusing optics with indication of the laser beam emission opening (arrow). laser beam emission opening at focusing optics D50 1‐12 Safety of the laser product 2020-01 Fig.
Eyes and skin may be exposed to laser radiation if the laser light is not placed under a protective cover! WARNING Laser light can burn the skin. Direct or scattered laser light can permanently damage your eyes. Ø Ø Ø Ø Ø In general, install the focusing optics and the processing spot in a protective housing or below a protective cover so that no laser light may be emitted during the production operation.
WARNING Incorrect wavelengths will lead to spontaneous leaking of radiation! If the focusing optics is used with a laser device whose wavelength does not match the focusing optics, this may damage the optics. This may cause uncontrolled emission of radiation. Ø Laser classes Only use laser devices that generate laser light with a wavelength that is suitable for the optics.
