- Page 14 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd (2) Precautions and maintenance 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 15 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd i. Try single spot operation, check whether the output energy of laser meet the requirements. If the output is not ideal, repeatedly adjust the resonant cavity; j. Cover the laser with outer hood.
- Page 16 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd single-chip microprocessor, which can be used to adjust the output energy of power and the repeated frequency. The system also features its multiple linked protections, ensuring the emergency stop of the power under abnormal conditions.

- Page 18 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd 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.
- Page 19 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd The resistance rate of the deionized water is required to be higher than 0.5MΩ—cm. After some time of use, the deionized water’s resistance rate will be lowered down 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 21 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd Attachment 3: Laser Alignment If the optical path get loosen after long-distance transport, or if the output spot is not round any more because of the operator misuse, you need to re-adjust the optical path. Generally we need to use of a ceramic dimmer, a piece of black paper also works if you don’t have the dimmer.
- Page 22 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd 3.3 Laser Alignment This is not a must-do when you firstly receive this machine. Only when you find the laser spot is not round any more or the laser energy becomes very weak, you may consider to do laser alignment.
- Page 23 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd Note: We have align the laser beam before shipping,so after you got the machine, no need to align the laser beam. If needed, just a slight change. If there are any damage or big movements of the inside parts (especially the mirrors and chamber), then maybe you need a big adjustment.
- Page 24 German Technology | Made in China Wuhan Questt Asia Technology Co., Ltd Laser Alignment in Fiber Mode When laser beam is delivered through fiber cable, we have to make sure the output beam comes out from exactly center of the fiber core. If there is any deviation, the output energy will be affected or even worse the fiber cable will be burnt.
