1. Remember not to start the metal laser cutting machine during thunder and lightning.
2. Please keep the place of the metal laser cutting machine dry.
3. Keep the cooling water level not exceeding the maximum allowable value.
4. There is no protection for the section of light path from mirror B to mirror C. When cutting and debugging the light path, please be careful not to put any part of the body into this section of light path to avoid injury.
5. When the ambient temperature is greater than the maximum allowable value, the equipment will not be able to adequately dissipate heat, which will reduce the operating stability of the equipment; when the ambient temperature is less than the minimum allowable value, it may cause the water in the laser to freeze and cause the laser tube to rupture .
6. The laser current of the metal laser cutting machine determines the laser energy, but when the current is greater than the allowable value, the laser energy will decrease, and if the current exceeds the allowable value for a long time, it will greatly affect the service life of the laser.
7. The power supply of the metal laser cutting machine: The fluctuation of the power supply voltage will cause the equipment to work unstable, and the high voltage will cause permanent damage to the equipment power system.
