The laser marking machine is marked with a laser beam on a variety of different material surfaces. The effect of marking is to expose the deep material through the evaporation of the surface material, thus engraving exquisite patterns, trademarks and words.

Laser marking machine is divided into, CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine, the current laser marking machine is mainly used in some requirements more sophisticated, more accurate occasions The Used in electronic components, integrated circuit (IC), electrical appliances, mobile communications, metal products, tool accessories, precision instruments, glasses watches and clocks, jewelry accessories, auto parts, plastic keys, building materials, PVC pipe. But the laser marking machine does not light how to do?

Symptom: are out of light is not normal, in the high side, string into the ammeter, visible ammeter shows abnormal, or a long time there is a current, or when there is no time, sometimes not controlled.

Failure reasons: the main reason is the choice of laser type is wrong, the motherboard, wiring board, power supply or control line connection and cooling water circulation system caused by failure.

Method of exclusion:

1, parameter settings, see the laser type is correct, it is the main reason for continuous light failure.

2, pull the nine core control line to see if there is a loose control line. The connection is unreliable.

3, the power on the control line (nine core line) unloaded, according to the laser power button to analyze the power supply or motherboard failure.

4, shot is not normal, that power problems.

5, burst normal, indicating no power failure.

6, the power is normal, connected to the control line, with a multimeter to measure the switch board on the switch control pin, do not light, the normal voltage of 4 volts above, less than 3 volts, the motherboard output is not normal; The voltage should be below 2 volts and output above 2.5 volts is not normal.

7, to see whether the water cycle is normal, whether the flow sometimes no water protection is a problem.
