CO2 laser marking machine may be dangerous if it is not operated properly during operation, so novices without professional training are not recommended to operate the equipment alone, so as not to understand its structure and cause accidents, and CO2 laser marking machine or CO2 laser cutting The wavelength of the machine laser is 1064nm. When the laser marking machine is processing, if it touches the human skin, it will burn the skin and cause certain damage. How to avoid CO2 laser marking machine from burning the skin? 1. The operator must be trained by a professional laser equipment manufacturer to understand the structure and performance of the CO2 laser marking machine, and master the relevant knowledge of the marking system; 2. Observe the safe operation of the CO2 laser marking machine 3. Before making sure whether the material to be processed can be irradiated or heated by laser, do not process the laser engraving without authorization, so as to avoid the potential danger of smoke and steam; 4. When watching at close range, you must wear laser protective glasses that meet the regulations to avoid damage to your eyes; 5. When you stop working, you need to turn off the laser or the main power supply; 6. Do not place paper around the laser beam without a safety cover , cloth or other flammable items and materials; 7.

If any abnormality is found during processing, it should be shut down immediately, and a professional should troubleshoot in time or ask the superior supervisor for instructions; 9. When using gas cylinders, avoid crushing the welding wires to avoid electric leakage accidents; 10. Keep the CO2 laser marking machine machine The body and the surrounding area are clean, orderly, and free of oil, and the workpieces, plates, and waste materials are placed according to regulations; 11. During the laser processing process, always pay attention to the operation of the laser head to prevent the engraving or cutting of the laser marking machine from exceeding the effective engraving range , increase the defect rate; 12. After inputting the new workpiece program, it should be trial run first, and check its operation. 13. During maintenance, high-voltage safety regulations must be followed, every 40 hours of work or weekly maintenance, every 1000 hours of work or every During the six-month maintenance, it must be carried out in accordance with the regulations and procedures.
