Do a good job in four steps without worrying about the light coming out of the laser cutting machine

The so-called laser cutting machine depends on the laser. If the metal laser cutting machine encounters the situation that the equipment does not emit light during the use, it will be a headache. However, you should not worry too much. In case of such failure, the first thing to do is to check the laser cutting machine equipment by yourself. You can follow the following four steps:

Do a good job in four steps without worrying about the light output of the laser cutting machine:

1. Check whether the water circulates normally and let it circulate normally. If the water protection is broken, it can be short-circuited for use;

2. If there is no light, the power supply may fail and need to be replaced. Point presetting to see whether the ammeter swings. If not, use a multimeter to measure whether the laser power supply is powered on by 220V,

3. If the light is out, the potentiometer is broken and needs to be replaced. You can also test whether the water protection is broken by GND ground wire and P water protection nipple on the power supply, and short circuit+5v and AIN to check the maximum output power,

4. If yes, it means that the card is normal. There is no possibility that the signal of the card is faulty. If the program does not work, the connecting card can use a multimeter to measure whether there is more than 3v DC voltage between the 15H or 16L angle and the 14 angle
