Laser engraving machine is a type of laser marking machine. Mastering methods and careful maintenance are necessary in use and maintenance to ensure that the machine can play its role more stably. The laser engraving machine should have a well grounded laser power supply, and the machine bed should have good grounding protection. The ground wire should be a dedicated ground wire with a resistance of less than 4 Ω. The necessity of grounding is:
1. It can ensure the normal operation of the laser power supply,
2. Can extend the service life of laser tubes,
3. It can prevent external interference from causing machine tool jumping,
4. Prevent accidental circuit damage caused by high-voltage discharge.
The ambient temperature and humidity should be within the range of 5-35 ℃. It should be noted that if used in environments below freezing point, the following measures should be taken:
To prevent the circulating water inside the laser tube from freezing, the water should be drained after shutdown;
When starting up, the laser current needs to be preheated for more than 5 minutes before it can work. In cloudy, rainy and humid environments, the laser power supply needs to be preheated for a longer time. Only after removing moisture can high voltage be applied to prevent breakdown of the high voltage circuit.
