Not out of light, the laser power is bad. (less likely is laser tube bad) (check the laser tube high pressure end spark phenomenon, the ignition to burn the laser power supply board and electronic components). The laser power supply fan does not turn, with pencil test of laser power supply 220V port, if there is power. There is electricity, the power of the laser is bad. (maintenance or replacement of the power supply); no power, check the laser power switch, the line.


Machine on but laser not coming out, the operator is not very familiar with the process of machine operation.

To check the following aspects

1, laser power switch is open.

2, the water tank is open.

3, the machine operation panel, the power is correct. Whether the computer software parameters are correct or not.

4, optical path is normal. (according to the light to see if the laser tube is bright, light and laser head is not light, then there is a problem of light path)
