How to check if the laser cutting machine suddenly stops emitting light?

Firstly, observe the current indicator on the panel to see if there is any current. If there is no current, check if the laser power supply of the machine is connected, and if the circuit is loose or detached; If there is current, you should check if there is any problem with the hardware, check if the lens is broken, if the laser tube outlet hole and lens are contaminated, and if the optical path is severely offset.

Next, whether the cold water system is normal: No water: No water: Check if the water pump is damaged or not powered on; Water connection: Check if the water inlet and outlet are connected in reverse or if the water pipe is broken.

If everything above is still normal, we need to see if the spot light can produce light. If so, we need to check the optical couple connection between the control panel and the power supply. If the laser cannot emit light, you can contact the manufacturer for technical assistance.
