Note on the use of laser cutting machine glass CO2 laser tube is as follows: First, please use the cooling water first, use the principle of low-in and high-out, adjust the position of the outlet pipe, ensure that the cooling water is filled with the cooling pipe, there is no bubble in the pipe, and then turn on the power. Requirements: The cooling water is soft water (distilled water or purified water), and the temperature of the cooling water should always be paid attention to. The water temperature should be controlled within the range of 25 ° C to 30 ° C. It should not be too high or too low, especially in the summer, once the water temperature is too high, The cooling water should be replaced or shut down for a period of time: the cooling water in the cold area should not freeze. Especially after the laser is stopped, the cooling water should not be stored in the laser tube to prevent the cooling water from freezing and causing the crack. (Special attention: users who use AC power, the cooling water tank must be grounded);
Second, the two support points of the laser tube should be at the point of 1/4 of the total length of the laser tube to ensure the flow rate of the cooling water is 2L-4L/min; otherwise, the effect is not good, it will cause the mode hopping, and the spot will change several points to cause power. The cooling water return port must be covered by water in the water tank, otherwise the cooling water in the laser tube will not be filled every time the power is turned on.
Third, pay attention to protect the output window of the laser, to avoid the smoke generated during the working process (including during the debugging optical path) from being sputtered onto the surface of the output window, to prevent the outer surface of the output window from being contaminated, and the power will drop. At this time, cotton or silk cloth can be used.轻轻Gently wipe the outer surface of the output window with absolute alcohol;
4. During the debugging process, adjust the laser support point or rotate the laser azimuth to achieve the best output effect, and then fix the laser. 5. Please pay attention to: avoid dust accumulation near the high voltage electrode, keep dry, high voltage end as much as possible Keep away from the metal to prevent high-voltage ignition.
6. During the use of the laser, there should be no scale formed in the cooling tube to avoid blockage of the cooling water and poor heat dissipation. Once found, the cooling tube can be cleaned with 20% dilute hydrochloric acid to remove scale.
7. The laser is a glass product that is fragile. Avoid local stress when installing and using.
8. Rationalize the application of laser tubes to save laser energy. The working current of the laser tube is best at 16 mA.
