The reason why the laser tube does not emit light and how to deal with it

The laser tube of the laser cutting machine is a very important configuration in the machine, but the laser tube will also have some problems during use. The more common phenomenon is that the laser tube does not emit light. Generally, there are three situations, one is suddenly there is no light, one is that the light of the laser tube is getting weaker and weaker when the laser tube is being used, and the last is that everything is normal when it starts to use, and there is no light when it is turned on the next day. The three situations mentioned above, Let's analyze it in detail below.

First of all, you should check the water flow of the water circulation of the laser machine. It can be seen whether the water outlet pipe has water. If the water outlet pipe is normal, it can be judged according to the specific situation. If it has been used for more than two hours, check whether there is water in the outermost layer of the co2 laser tube. If there is water, it is because the water temperature is too high to cause the laser tube to burst.

 

If there is no water in the outer layer of the laser tube, we will check the laser power supply at this time. Press the button on the power supply to see if the light can be emitted normally. If the light can be emitted normally, it means that the water protection device is malfunctioning. At that time, we need to check whether the water outlet of the sewage protection is blocked, and then clean it.

 

If there is no water in the outer layer of the laser tube, then we will check the laser power supply. There is a red button on the laser power supply. Press it to see if light is emitted. If it emits light, it may be a water protection device failure. The customer first checks whether the water outlet of the water protection is blocked, and then cleans the water protection, it is best to rinse it with water.

 

At this time, we must pay attention to the water inlet and outlet of the water protection, and we must not reverse it, otherwise the laser tube will be damaged. In addition, you can first short-circuit the PG on the laser power supply (connect it with a wire) but at this time, pay attention to check the water circulation, the water protection does not work, and the laser tube will still be damaged. If the light still does not come out, it means that the laser power supply is broken, and you can find the manufacturer to replace it. laser cutter

 

 

1) Check the water circulation of the laser machine. If the water flow does not circulate, please turn off the power and check whether the water pump or chiller plug is plugged in.

 

2) Check whether the ammeter of the laser cutting machine is normal. If it is normal, it may be a problem with the laser tube. Find the manufacturer to replace or repair it. If the ammeter is not normal, it is a problem with the laser power supply. Find the manufacturer to replace or repair it.
 

1) Check the water circulation of the laser cutting machine to see if the water is flowing out normally.

2) Check the ammeter of the laser cutting machine, press "out light" to see if the pointer of the ammeter is up. If it is below 5 mA, it means that the power supply is broken. Find the manufacturer to replace or repair it.

3) If the ammeter does not move, check whether our laser switch is turned on. If it is turned on, then see if the laser power indicator is on. If it is on, press the button on the laser power source and check the current hand pointer. If the pointer is moving and If it is less than 5 mA, the laser power supply is broken, or the maximum light intensity and minimum light in the software are emphasized to half, and then press to see if the ammeter pointer reaches 10-12 mA, if not, it is the laser power supply or The motherboard problem.

 

The above are some matters that should be paid attention to when the laser tube in the laser cutting machine does not emit light. If you cannot solve it by yourself, please contact the manufacturer as soon as possible.
