The reason why the laser head of laser engraving machine does not glow


In the daily use of laser engraving machine, it is often encountered that the laser head of the laser engraving machine does not glow. This article briefly introduces how to deal with the laser head of the laser engraving machine.


1. Press the test key on the operation panel to check whether the ammeter has current indication:


If there is no current, check whether the laser power supply is connected, whether the high voltage cable is loose or falls off, and whether the signal cable is loose.


If there is current: check whether the lens is broken, whether the light outlet hole of the laser tube and the lens are polluted, and whether the optical path is seriously deviated.



2. Check whether the water circulation system is normal:


No water: check whether the pump is damaged or not energized;


Water discharge: Check whether the water inlet and outlet are reversed or the water pipe is broken.



3, the point can emit light, computer-controlled engraving does not emit light, check the engraving machine control board to the power supply of the optical coupling line.



4, laser power supply board damage (manufacturer maintenance).



DY series CO2 laser power supply


1, flat structure design, light weight, using all aluminum shell design flat structure, 30% lighter than the conventional power supply.


2, cutting and engraving compatible: stable power, strong adaptability, fast response, suitable for cutting or engraving;


3, the laser power control is simple: can use analog signal 0-5V control laser power, also can use 5V PWM signal control.


4, the power supply itself has the open-circuit protection function: the use of safer, and significantly prolong the life of the power supply.


5, the power supply with manual test button, can quickly judge the fault, easy to maintain.


6, power supply with work indicator light, convenient troubleshooting.


7, two kinds of installation, strong adaptability, can be flat or vertical installation.
