What scares the technology most in the working process of the laser cutting machine is that the laser does not emit light. If the laser generator does not emit light, everything can not work normally, which will greatly endanger the production and manufacturing progress of the enterprise. Therefore, we must find out the reason why the equipment does not emit light, so as to reduce the property loss caused by the common failure of the laser cutting machine.

The solution of no light from the laser cutting machine:

1. Carefully observe the ammeter of the equipment and check whether there is a current indication. If there is no current indication, check the power circuit of the equipment;

2. Check the circulating water system of the equipment to find the reason why it does not shine. If the circulating water system is abnormal, the laser cutting machine cannot work normally;

3. If it is still impossible to determine the reason why the equipment does not shine according to the above two points, the manufacturer should be immediately sought for maintenance. When we find that the laser cutting machine does not shine, we must stop working immediately, and then we can use the above processing methods to detect the failure, so that we can ensure that the equipment can work normally, increase the application cycle time of the equipment, and produce a large amount of economic benefits for everyone.

Many practical operators are confronted with the problem that the laser cutting machine cannot emit light normally, but most people think that it is a common fault of the laser generator when dealing with this kind of situation. In fact, it is worth mentioning that there are many factors that cause no light, and we should first consider whether there is any neglect in the actual operation, That is, the laser cutting machine is not from all normal operating conditions due to poor actual operation.

First, check whether the laser power switch of the device is turned on; Also pay attention to whether the industrial chiller is turned on, and check whether the light output data signal, operation data signal and water maintenance data signal of the industrial chiller are normal;

Another thing is to carefully observe whether there are spare parts that do not work properly and cause no light. Check whether the laser tube emits light normally; Dark light indicates abnormality, and everything is normal in light pink; Whether the water output of the laser tube is normal; Check whether the laser light path of the laser is normal. Press the output light to check whether the laser tube is bright. If it is bright but the laser cutting head is not bright, then there is something wrong with the laser light path; Check whether the function key led panel light is normal, check whether the actual operation control panel of the equipment, output power or main parameters of the computer application are appropriate;

The most important thing is whether there is a common fault in the laser power supply. During the inspection, generally check whether the cooling fan of the laser power supply is rotating. If it is not rotating, it indicates that the common fault of the laser power supply requires the replacement of the switching power supply; Or immediately check whether the laser tube and laser power supply are normal when the light is emitted from the laser power data signal; If there is still no light, it indicates that the laser power supply has common faults, and the switching power supply needs to be replaced;

Finally, the most easily overlooked problem is the office environment of the equipment. Check whether the working voltage is less than 200V. The working voltage is too low to work normally.

After the laser cutting machine is turned on, if the light does not come out, most of these areas can be checked to identify the problem. For this situation, symptomatic treatment can be used. If there are a large number of other common problems or technical services related to the laser cutting machine, you can also care about everyone.
