First, please switch on the cooling water before use laser tube. According to the principle of low input and high output, adjust the position of the outlet pipe to ensure that the cooling water is full of the cooling pipe. Requirements: cooling water using soft water (distilled water or pure water), and often pay attention to the temperature of the cooling water temperature should be controlled at 25 ℃ and 30 ℃ scope, may not be too high or too low, especially in the summer, once found, high temperature cooling water should be replaced in a timely manner or stop to rest for a period of time, cooling water shall not be frozen cold regions, especially the laser after downtime, must not let water storage in the laser tube, so as to avoid water ice lead to crack. (special note: for ac users, the cooling water tank must be grounded);
Ii. The two supporting points of the laser tube should be on the point of 1/4 of the total length of the laser tube, ensuring the flow of cooling water at 2l-4l/min; Otherwise, the effect is not good, will cause mode hopping, spot change a few points lead to power drop; The cooling water inlet must be covered with water in the water tank, otherwise, the phenomenon of insufficient cooling water filling in the laser tube will occur every time the machine is switched off.
Three, pay attention to protect the output window of the laser, avoid the process of work (including the process of debugging light path) generated by the smoke sputtering to the surface of the output window, to prevent the external surface of the output window is polluted, the power will drop, then you can use absorbent cotton or silk cloth dipped in anaqueous alcohol to gently wipe the external surface of the output window;
Four, in the debugging process, by adjusting the laser support point or laser rotation orientation, in order to achieve the best output effect, and then the laser fixed.
Five, please be sure to pay attention to: avoid high pressure electrode near the accumulation of dust, to keep dry, high pressure end as far as possible away from the metal, in case of high pressure spark discharge.
Six, the laser in the use of the process, can not have scale in the cooling pipe formation, so as not to cause cooling water blockage, poor heat dissipation effect. Once found, clean the cooling tube with 20% diluted hydrochloric acid to remove scale.
Seven, the laser is glass, fragile. Avoid local force when installing and using.
Eight, rationalization of the use of laser tube, laser energy saving, laser tube operating current at the best point of 16 ma.
