In recent years, laser cutting machines have been widely used in the metal industry. The high efficiency of laser cutting technology has greatly promoted the transformation and upgrading of industrial technology. However, while enjoying the efficient production of laser cutting, how to do a good job of safety protection and reduce the radiation to the human body during use?
- Fire prevention
The laser cutting machine uses oxygen during cutting. Smoking should be prohibited in the cutting machine area, especially near the oxygen cylinder, to prevent hidden dangers and unnecessary damage
- Exchanging table
Make sure no one is standing near by exchanging tables when exchanging. If any emergency occurs during the exchanging process, immediately stop the process or press emergency stop.
- Check before operation
Whether the equipment and accessories are well connected to the grounding point. Poor grounding will shorten the life of the laser machine, and the high-voltage discharge will damage the control circuit and even threaten operator’s life! ! ! !
- Laser light path: When cutting and adjusting the light path, please be careful not to let any part of the body touch the light path to avoid injury! !
- Laser energy: The magnitude of the laser current determines the magnitude of the laser energy, but when the current is greater than the allowable value, the laser energy will drop, and if the current exceeds the allowable value for a long time, it will greatly affect the service life of the laser.
- Ambient temperature: When the ambient temperature is higher than the maximum allowable value, the equipment will not get sufficient heat dissipation, which will reduce the operation stability of the equipment; when the ambient temperature is lower than the minimum allowable value, it may cause the water in the laser to freeze and affect the use life.
- Ambient Humidity: Excessive humidity will cause laser high-voltage discharge, which will endanger personal safety and cause damage to the laser power supply.
- Power supply: The fluctuation of the power supply voltage will cause the equipment to work unstable; if the voltage is too high, it will cause permanent damage to the power supply system of the equipment. In order to avoid the electrical appliances and circuits of the machine from being burned out due to excessive voltage, a voltage stabilizer is strongly recommended.
- Protection for the skin
Laser cutting has certain damage to skin tissue, which can be repaired by itself. It should be noted that long-term exposure to laser light may cause skin burns or leave scars. Therefore, when performing laser cutting work, the protection of the skin must also be given great attention.
For safety reasons, it is recommended that laser operators wear long-sleeved clothes to prevent skin burns caused by direct laser radiation on the skin, and to prevent scalding caused by molten slag splashing on the skin. Do not touch the cut parts immediately, wear gloves to avoid scalding by residual heat
- Protection for the respiratory tract
When performing laser cutting work, pay attention to the protection of the respiratory tract. Install the supporting dust removal device, try to operate in an environment with unobstructed air, and wear a mask as much as possible.
