No matter what machine we use, safety is the most important, so today I want to write something about the safety of laser cutting machines. The reason why the laser cutting machine is the main part is that I am engaged in this industry, but I think these safety precautions are applicable to all laser machines, so you can also consider the use of optical fiber laser cutting machine as safe.

1. When the laser cutting machine is working, the operator must stay with the laser cutting machine to avoid unnecessary loss. This is a very basic principle.

2. During the operation of the laser cutting machine, the protective cover above the laser machine must be put down to prevent the laser beam from deflecting and hurting people. For this problem, some enterprises now have good solutions, such as open cover protection.

3. As there are laser parts and high-pressure parts inside the laser cutting machine, it is prohibited to dismantle the laser machine of non professionals.

4. All parts of the machine must be grounded completely and reliably to prevent static electricity from being cut off.

5. Since this laser is not visible light, it is strictly prohibited to place the equipment near flammable and explosive substances to prevent the laser from deflecting towards the ignition source.

6. It is strictly forbidden to have irrelevant total reflection or scattered laser beam reflected inside the laser cutting machine to harm people.

7. The operator must observe the laser machine at any time during work (such as irregular processing, abnormal sound of the machine, temperature of circulating cooling water, etc.)

8. It is prohibited to push or pull the laser head and its gantry when the machine is powered on.

9. There is no strong electromagnetic interference and strong current in the machine environment.

10. When the voltage is unstable, it is forbidden to open the laser cutting machine, or a voltage regulator must be used.

11. It is prohibited to use laser cutting machine without training.

12. The continuous working time of the laser cutting machine shall not exceed 5 hours (more than half an hour of rest is required)

13. The water circulation must be kept clean, and the water temperature cannot exceed 20 ℃ - 30 ℃ (purified water is recommended)

14. When the maximum data appears in the ammeter, it is forbidden to turn on the laser machine. Otherwise, the laser power will be damaged and the life of the laser tube will be shortened.

15. Basic limit of laser power used (i.e. the maximum ammeter shall not exceed 20mA)

16. If the machine functions abnormally or catches fire, please cut off the power immediately.
