As a professional in the field of laser technology, I’ve encountered various issues with laser cutting machines, one of the most concerning being the reasons why the laser cutting machine does not emit light. This problem can halt production and lead to frustration, especially in critical projects. In this article, I will explore the common causes behind this issue, from electrical failures to alignment problems. Understanding these factors is crucial for troubleshooting effectively and ensuring that your laser cutting machine operates at peak performance. Let’s delve into the reasons behind this light emission problem!

The laser tube of the maszyna do cięcia laserowego does not emit light. There are usually three kinds, one is that the light is suddenly not emitted, the other is that the light with the laser tube is getting weaker and weaker, and the last one is to start using everything normally, and then the next day. There is no light when you turn it on.

Regarding the laser tube caused by the above three cases, the specific reason is as follows:

Ⅰ About the Reason for Laser Cutting Machine Does not Emit Light

Check the water circulation of the laser machine to see if the nozzle of the nozzle is out of water. A If the outlet water is normal, then ask the customer how long it took from the start to the present. Please be sure to answer the question truthfully, otherwise it will affect the correct judgment. If the customer says that it is used for one morning or two more For more than an hour, please check the outermost layer of the CO2 laser tube for water. If there is water, it is because the water temperature is too high and the laser tube is broken. 

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 it is out. If it is out, it may be a malfunction of the water protection device. At this time, please The customer first checks whether the water outlet protection outlet is blocked, and then cleans the water protection. It is best to rinse it with water. 

At this time, we should pay attention to the water inlet and outlet of water protection. It must not be reversed, otherwise, the laser tube will be damaged. The second method is to short the PG on the laser power supply (connected with a wire). However, pay attention to check the water circulation. The water protection does not work and the laser tube will be damaged. If it still does not emit light, it means that the laser power supply is broken, find a replacement. 

Ⅱ About the Reason Why the light used in the Laser Tube is Getting Weaker

⒈Check the water circulation of the laser machine when laser cutting machine does not emit light. If the water flow does not cycle, please check whether the water pump or chiller plug is plugged in after the power is turned off.

⒉Check if the current meter of the laser cutting machine is normal. If it is normal, it may be a problem with the laser tube. Look for replacement or repair by the manufacturer. If the ammeter is not normal, it is a problem of the laser power supply. Look for replacement or repair.

Ⅲ Start Using Everything is normal, there will be no light after the next day.

⒈If laser cutting machine does not emit light, Check the water circulation of the laser cutter to see if it is out of water.

⒉Check the current meter of the laser cutting machine, press “light out” to see if the ammeter pointer can be played up. If it is below 5 mA, it means the power supply is broken, find the manufacturer to replace or repair.

⒊If the ammeter does not move, check if our laser switch is turned on. If it is turned on and then see if the laser power indicator is on, press the button on the laser power to see the current hand pointer. If the pointer is moving and less than 5 mAh, the laser power supply is broken, or the maximum light intensity and minimum light in the software are emphasized to 50%, then press the current meter pointer to 10-12 mA, if it is not reached, it is laser power or The problem with the motherboard.

Wniosek

Understanding why laser cutting machines may not emit visible light is crucial for users and operators. The reasons include the use of infrared wavelengths, the machine’s enclosed cutting environment, and stringent safety protocols designed to protect users.

By recognizing these factors, operators can appreciate the advanced technology behind laser cutting machines and utilize them effectively for a wide range of applications. Whether you’re involved in metal fabrication, woodworking, or signage production, knowing how your laser cutting machine operates will enhance your overall experience and safety.
