The Maintenance of Laser Engraving and Cutting Machine

1. Please turn on the cooling water before use, adopt the principle of low inlet and high outlet, adjust the position of the outlet pipe to ensure that the cooling water is filled with the cooling pipe, and no bubbles can be stored in the pipe, and then turn on the power. Requirements: Use soft water (distilled or purified water) as the cooling water, and pay attention to the temperature of the cooling water. The water temperature should be controlled within the range of 25℃-30℃, not too high or too low, especially in summer, once the water temperature is found to be too high, The cooling water should be replaced in a timely manner or shut down for a period of time: the cooling water in cold areas should not be frozen, 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 bursting. (Special attention: for users using 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 that the flow rate of the cooling water is 2L-4L/min; otherwise, the effect is not good, it will cause mode jumping, and the spot changes to a few points, resulting in power Down; the cooling water return port must be covered with water in the water tank, otherwise the cooling water in the laser tube will be dissatisfied every time the power is turned off.

3. Pay attention to protect the output window of the laser, avoid the smoke generated during the work (including the debugging of the optical path) from splashing onto the surface of the output window, prevent the outer surface of the output window from being polluted, and the power will decrease. In this case, use absorbent cotton or silk cloth Dip absolute alcohol and gently wipe the outer surface of the output window;

4. During the debugging process, adjust the laser support point or rotate the laser orientation to achieve the best output effect, and then fix the laser

5. Please pay attention to: avoid accumulation of dust near the high-voltage electrode, keep it dry, and keep the high-voltage end as far away from the metal as possible to prevent high-voltage ignition and discharge.

6. During the use of the laser, there should be no scale formation in the cooling tube, so as to avoid clogging of the cooling water and poor heat dissipation. Once found, the cooling pipe can be cleaned with 20% dilute hydrochloric acid to remove scale.

7. The laser is made of glass and is fragile. When installing and using, avoid local stress.

8. Reasonable application of laser tube to save laser energy. The best working current of laser tube is 16 mA.
