How to maintain the laser in the laser cutting machine

The laser in the laser cutting machine is a sensitive current component. It is better to choose a slow-start circuit, and it must work within the limited current, and it must have a relatively strong surge absorption circuit. In normal use, you can pay attention to it. You can warm up the laser first, and then turn it on after the temperature control is balanced. If you use it, you can adjust the power to the minimum before shutting down, and then turn it off. When you turn on it, adjust it from the minimum to the upper to avoid the circuit. The overshoot has caused damage to the laser, and the stability of the power supply must be ensured. In order to ensure that the laser is always in normal working condition, after two weeks of continuous work or after a period of non-use (to ensure that the equipment is clean), the components in the optical path such as YAG rod, dielectric film and lens protection glass should be firstly processed before starting up. Check to make sure that there are no abnormal phenomena such as dust pollution and mildew on the optical components. If the above phenomena occur, they should be dealt with in time to ensure that the optical components will not be damaged under strong laser irradiation. The purity of the cooling water is the key to ensuring the laser output efficiency and the life of the laser concentrating cavity components. During use, the conductivity of the internal circulating water should be checked once a week to ensure that its conductivity is 30.5MWu0026middot;cm. The internal circulating water must be replaced once a month. For deionized water, the conductivity of the newly injected pure water must be 32MWu0026middot;cm. Observe the color change of the ion exchange column in the cooling system at any time. Once the color of the resin in the exchange column changes to dark brown or even black, the resin should be replaced immediately. Equipment operators can often check the laser output spot with black photo paper. Once spot unevenness or energy drop is found, the laser resonant cavity should be adjusted in time to ensure the beam quality of the laser output. The typical light spot image is as follows: The adjusted light spot is not adjusted. The adjustment of the laser resonator Note: When the strong laser is directly irradiated to wood and other flammable materials, an open flame will be generated, and it should be placed on the light path of the laser output during the debugging process. A piece of black metal material with good absorbing performance is used as a beam stopper to prevent fire accidents. In a high temperature or humid environment, during laser operation, you should always pay attention to observe whether there is 'condensation' caused by low water temperature on the cooling water circulating pipe or laser condenser cavity. The occurrence of 'condensation' will cause YAG The damage to the end face of the crystal causes the output power to drop and even the light cannot be emitted. Be sure to pay attention to it during use. If there is 'condensationPay attention to properly adjust the lower limit set temperature of the high temperature controller before starting up. The maintenance of the laser must be carried out by specially trained personnel, otherwise it is easy to cause serious man-made damage.
