1. Generally, fiber laser marking machines will be equipped with protective devices. If the laser temperature exceeds 35 degrees, it will automatically stop emitting light and a warning will appear.
2. You can turn off all the power of the fiber laser marking machine, do not use the equipment temporarily, let it stand for a few minutes and then turn it on again.
3. If it keeps prompting that the temperature of the fiber laser is too high, it means that the laser may be damaged and needs to be replaced.
Note: When purchasing laser equipment, be sure to pay attention to whether the laser marking machine manufacturer includes after-sales service. A good after-sale service can increase the service life of the machine and reduce the cost.
