1、 When using, please connect the cooling water first, adjust the position of the water outlet pipe according to the principle of low in and high out, ensure that the cooling water is full of the cooling pipe, and there is no bubble in the pipe, and then turn on the power supply. Requirements: The cooling water shall be soft water (distilled water or purified water), and attention shall be paid to the temperature of the cooling water. The water temperature shall be controlled within the range of 25 ℃ - 30 ℃, and shall not be too high or too low, especially in summer. Once the water temperature is found to be too high, the cooling water shall be replaced or shut down for a rest period of time: the cooling water shall not freeze in cold areas, especially after the laser is shut down, Do not allow cooling water to be stored in the laser tube to avoid freezing of cooling water and explosion. (Special attention: the cooling water tank must be grounded for users using AC power);

2、 The two supporting points of the laser tube shall be located at 1/4 of the total length of the laser tube, and the flow of cooling water shall be 2L-4L/min; Otherwise, the effect is not good, which will cause mode hopping, and the light spot will change several points, leading to power reduction; The cooling water return port must be covered by water in the water tank, or the cooling water in the laser tube will not be fully filled every time the machine is turned off.

3、 Pay attention to protecting the output window of the laser to prevent the smoke generated during the operation (including the process of debugging the optical path) from splashing onto the surface of the output window, so as to 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 gently wiped with absorbent cotton or silk cloth dipped in anhydrous alcohol;

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

5、 Please pay attention to: avoid dust accumulation 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 spark discharge.

6、 During the use of the laser, no scale can be formed in the cooling pipe, so as to avoid blocking the cooling water and poor heat dissipation effect. Once found, the cooling pipe can be cleaned with 20% diluted hydrochloric acid to remove scale.

7、 The laser is glass and fragile. Avoid local force during installation and use.

8、 Rationalize the application of laser tube, save laser energy, and the working current point of laser tube is 16 mA.

The laser tube is a consumable of CO2 laser machine. Reasonable and correct use can extend its service life and affect the quality of processing. Please refer to

Above.
