How precautions for using glass CO2 laser tubes

Precautions for using glass CO2 laser tubes

1.When using CO2 laser tube and CO2 laser power supply, please first connect with the cooling water, follow the principle of low inlet and high outlet, adjust the position of the outlet pipe to ensure that the cooling water is filled with the cooling pipe, and there are no bubbles inside the co2 laser pipe. Then turn on the power. Requirement: The cooling water should be soft water (distilled water or purified water), and the water temperature of the cooling water should be regularly paid attention to. The water temperature should be controlled within the range of 25 ℃ -30 ℃, and should not be too high or too low, especially in summer. Once the water temperature is found to be too high, the cooling water should be replaced in a timely manner or stopped for a period of rest. In cold areas, the cooling water should not freeze, especially after the laser is stopped, the cooling water should not be stored in the laser tube/laser lamp, To prevent the cooling water from freezing and causing explosions. (Special attention: For users using AC power, the cooling water tank must be grounded);

2.The two supporting points of the high power CO2 tube should be located at a point 1/4 of the total length of the 1250mm laser tube, ensuring a cooling water flow rate of 2L-4L/minute; Otherwise, the effect is not good, which will cause mode hopping, spot change at several points, and result in a decrease in power; The cooling water return port in the water tank must be covered with water, otherwise the cooling water in the 60W laser tube will not be fully filled every time the co2 laser engraving machine is turned off.

3.Pay attention to protecting the output window of the laser to prevent the smoke generated during the operation (including the process of debugging the optical path) from splashing onto the surface of the output window, so as to prevent the external surface of the output window from being polluted and the laser power will drop. At this time, gently wipe the external surface of the output window with Cotton wool or silk cloth dipped in anhydrous alcohol;

4.During the debugging process, adjust the laser support point or rotate the laser orientation to achieve the best output effect, and then fix the laser

5.Please be careful: avoid dust accumulation near the high-voltage electrode, keep it dry, and keep the high-voltage end as far away from the metal as possible to prevent high-voltage ignition and discharge.

6.During the use of the CO2 laser cutting equipments, no scale should form inside the cooling pipe to prevent blockage of the cooling water and deterioration of the heat dissipation effect. Once discovered, the cooling sealed glass CO2 tube can be cleaned with 20% dilute hydrochloric acid to remove scale.

7.The laser tube is made of glass and is fragile. Avoid local stress during installation and use.

8.Reasonably apply laser tubes to save laser energy, and the optimal working current of the laser tube is 16 milliamperes.

1.Inscription depth:

1. As soon as it shines, it cannot be deeply engraved:

First, check whether the supporting point of the CO2 engraver‘s  laser tube is reasonable, whether the light intensity is set too small, whether the light path is offset, whether the focal length is correct, whether there are scratches and dirt on the surface of the ytterbium plate, and whether the flow and flow pressure of the cooling water are normal. If the above items are OK, check whether there are scratches and dirt on the mirror plate in the light outlet of the laser tube. If it is also normal, it is a quality problem of the laser tube of CO2 laser cutter by itself.

2. Shine for a while before it deepens:

To solve this problem, first check whether the supporting point of the laser tube of CO2 cutter is reasonable, whether the water temperature exceeds 30 degrees, whether the lens is heated during operation, whether the flow and flow pressure of cooling water are normal, and whether the cooling water is clean. Then check the laser tube after the above is normal

2.High voltage ignition and discharge: Check for dirt and moisture around the high-voltage head, and whether it is too close to the metal part of the co2 laser cutting machine; In addition, whether the high-voltage connection device of the laser power supply has fallen off the support, and whether the high-voltage connection device is internally disconnected and damaged. If the above is normal, then it is a quality issue with the1450mm laser tube

3.Laser tube broken, cracked, water cooled head detached:

1. Is the water temperature controlled within the range of 25 ℃ -30 ℃? Cooling water in cold areas should not freeze, especially after the laser is shut down, and should not be stored in the laser tube.

2. Whether the luminescence works under the control of water protection; (Test whether the luminescence will light up or not with the on-off of water)

3. Is there any phenomenon of water pipes being broken down in the waterway.

4. Is there any steam bubbles inside the 80watt laser tube.

5. Whether the water pressure and flow are normal; Is the water flow direction low in and high out.

If items 6.1 to 5 are normal, then it is a quality issue with the laser tube itself.

Before using and replacing RECI laser tube, carefully read the above content to avoid unnecessary losses caused by misoperation
