How to tell the laser tube manufacturer how to use the laser tube
1. When using, please connect the cooling water first, select the principle of low in and high out, adjust the direction of the outlet pipe, ensure that the cooling water overflows the cooling pipe, there is no bubble in the pipe, and then turn on the power supply. Requirements: soft water (distilled water or purified water) should be used as cooling water, and the water temperature should be controlled at 25 ℃ - 30 ℃. It should not be too high or too low. Especially in 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 cold areas should not be frozen, especially after the laser is shut down The water is stored in the laser tube to prevent the cooling water from freezing and cracking. (special attention: for users using AC power, the cooling water tank must be grounded)
2. The two supporting 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 cooling water flow rate is 2l-4l / min; otherwise, if the function is not good, it will cause mode skipping, and the light spot will change several points, resulting in power reduction; the cooling water return port in the water tank must be covered by water, otherwise the cooling water in the laser tube will not be fully filled every time the machine is turned off.
3. Pay attention to the maintenance of the output window of the laser to prevent the smoke generated during the operation (including the adjustment of the optical path) from splashing on the surface of the output window, and prevent the external surface of the output window from being polluted and the power will drop. At this time, the external surface of the output window can be quietly scrubbed with absorbent cotton or silk cloth dipped in anhydrous alcohol.
4. In the debugging process, adjust the laser support point or rotate the laser direction to achieve the best output effect, and then fix the laser.
5. Please pay attention to: prevent dust accumulation near the high voltage electrode, keep it dry, and keep the high voltage end away from the metal as far as possible to prevent high voltage ignition and discharge.
6. In the process of using the laser, there should be no scale in the cooling pipe to prevent the cooling water from blocking and the cooling effect getting worse. Once found, the cooling pipe can be cleaned with 20% dilute hydrochloric acid to remove scale.
7. Reasonable use of laser tube can save laser power. The best operating current of 400W laser tube is 26 ma.
8. The laser is made of glass and fragile. When the device is used, it can prevent partial force.
