The CO2 laser mixed gas in the CO2 laser marking machine is a high-pressure filling gas, and it should be used after decompression and pressure reduction. The packaged gas cylinders have a service life limit, and all expired gas cylinders must be sent to a department for safety inspection before they can be used. When the last bit of gas is left in each bottle, the residual pressure in the bottle should be kept at 0.5MPa, and the residual pressure Should not be less than 0.25MPa at least. The bottle valve should be closed to ensure the gas quality and safety of use. Bottled gas products should be sorted and stacked during transportation, storage and use. Combustible gas and combustion-supporting gas should not be stacked together, and should not be near open flames and heat sources, and should be kept away from fire, oil wax, exposure to the sun, or re-throwing. , Do not hit, it is strictly forbidden to start arc or arc on the gas cylinder, and it is strictly forbidden to load and unload savagely. Because the laser can emit powerful laser light (interferable light), if you look directly with your eyes, it will burn the retina and even lose your eyesight. At the same time, there is a risk of burns.


General matters needing attention:


1).When using the laser, you must wear protective glasses.


2).There will often be unexpected reflected light into the eyes. Therefore, pay great attention to the direction of the emitted light, and at the same time check that there is no reflective wall or the like.


3).It is best to cover the entire laser device.


4).For devices that emit powerful laser light, a light-trapping device should be equipped.


5).Because the laser device uses a high-voltage power supply, you must pay attention to it during operation.


The laser marking machine can print a variety of characters, symbols and patterns, etc., and the character size can range from millimeters to micrometers, which has special significance for product anti-counterfeiting. The focused ultra-fine laser beam is like a tool, which can remove the surface material of the object point by point. Its advanced nature lies in the non-contact processing of the marking process, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed article; After the laser is focused, the size is small, the heat-affected area is small, and the processing is fine. Therefore, some processes that cannot be achieved by conventional methods can be completed. The "tool" used in laser processing is the focused light spot, no additional equipment and materials are needed. As long as the laser can work normally, it can be processed continuously for a long time. The laser processing speed is fast and the cost is low. Laser processing is automatically controlled by a computer, and no human intervention is required during production.
