e) Other parts: High voltage electrodes, insulation base plate, positioning bracket, adjustable diaphragm frame and laser holder. Precautions and maintenance (2). As the machine is highly precise equipment whose discharging features the high pulse voltage and charging features the large capacity, and the laser focusing energy is highly centralized, the operators must obtain professional knowledge and skills before they work on the machine. - Page 12 the output is not ideal, repeatedly adjust the resonant cavity; j. Cover the laser with outer hood. D. Nd ：YAG crystal is the core part of the laser, and is fairly expensive. Therefore, it should be installed with great care. The two end faces of Nd ：YAG crystal rod is absolutely parallel to each other and has high cleanliness.
- Page 13 A. Step-up/rectification circuit: it employs the single-phase stepping up, which converts AC220V into DV500V that supplies power to the charging circuit. B. Charging circuit The charging circuit is composed of the IGBT switch tubes. This charging mode will increase the repetition rate of the circuit.

- Page 15 and vaporizing that pass the optical energy into the in-depth part of the material. Therefore, in actual applications, if the large penetration depth is required, the negative off-focus operation should be carried out. When thin materials are welded, the positive off-focus operation is needed. (1) Microscope This machine employs the binocular zoom stereo microscope, featuring its clear and stereo vision.

rod) ,Xenon lamp, lamp electrode of the laser. The deionized water with absorbed heat will pass by the heat exchanger discharging the heat and flow back to the water tank. The resistance rate of the deionized water is required to be higher than 0.5 MΩ—cm. After some time of use, the deionized water’s resistance rate will drop and it may have impurities, dirt or turbidity that will make the xenon lamp not lightened or pollute the laser cavity and glass tube, and lower the luminous efficiency. - Page 17 Power supply switch key Adjust the laser beam, microscope and Crossing use these 3 screw to alignment.

When the pedal switch is closed and the word “Laser” is displayed on the screen, the liquid crystal light valve can shield the flashing light. Under non-work conditions, the word “ Laser” won’t be displayed. Working current: It displays the discharging current for the laser. When the pulse width is identical, the higher the working voltage is, the higher the output energy of laser will be. -
