Laser cutting machine does not emit light during operation
- (1) Alarm, connect the water inlet and outlet at the back of the water tank with a water pipe, and energize the water tank to see if there is an alarm. If the alarm occurs, the water tank is broken. If there is no alarm, the fiber laser cutting machine has no water passage, check whether the water pipe is bent or pressed by something, and whether the water in the water tank is debris (clean water in the water tank)
- (2) No alarm, check whether the power fan of the fiber laser cutting machine is spinning. The power fan of the fiber laser cutting machine rotates, and the laser power supply is short-circuited with a wire.
