1, the laser tube of the two support points to the total length of the laser tube 1/4 points, to ensure that the flow of cooling water in the 2L-4L / min; otherwise the effect is not good, can cause jump mode, the spot becomes a few points lead to power Drop; cooling water back in the water tank must be flooded cover, or turn off the laser tube when the water cooling water irrigation dissatisfaction.
2, pay attention to the protection of the laser output window, to avoid the work process (including debugging light path) generated by the smoke splashing to the output window surface to prevent the output window is contaminated surface, the power will drop, when available cotton or silk Dipped in anhydrous alcohol gently wipe the outer surface of the output window;
3, in the debugging process, by adjusting the laser support point or rotation of the laser orientation, in order to achieve the best output, then the laser fixed
4, be sure to pay attention to: to avoid accumulation of dust near the high-voltage electrode, to keep dry, high-pressure end as far as possible from the metal to prevent high voltage spark discharge.
5, the laser in use, can not have scale in the cooling pipe to form, so as to avoid blocking the cooling water, cooling effect worse. Once found, clean the cooling tube with 20% dilute hydrochloric acid.
