Notice on the precautions for the use of CO2 laser tubes in summer


With the influence of factors such as the increase of temperature in summer, the increase of air humidity, and the sharp increase of electricity load in some areas, the failure rate of CO2 laser tubes in summer is obviously higher. In order to ensure the stability of laser tubes in summer, reduce the failure rate of laser tubes Attention should be paid in summer:


1. In summer, the laser tube cannot use antifreeze, electrolyzed water, glass water and other liquids with antifreeze function as the cooling medium. The antifreeze, electrolyzed water, glass water and other liquids must be replaced with pure water.


2. Regularly clean the water chiller and water circulation system of the laser equipment to ensure that the water protection switch of the laser equipment functions normally and the waterway is unblocked. The water flow should meet the water flow requirements of the laser tube.


3. The water temperature of the chiller should be controlled below 35°C, and the temperature difference between the room and the room should not exceed 5℃ (positive in winter and negative in summer) to avoid failures such as deformation of the laser tube cavity, inner tube rupture, and window mirror explosion caused by excessive temperature difference.


4. Carry out the investigation of the high and low voltage wires of the laser tube to ensure reliable connection and protection of the high and low voltage wires of the laser tube. Once the high and low voltage wires are found to be aged or broken down, the high and low voltage wires should be replaced immediately.


5. All laser tubes (≥120W) need to use 50kV high-voltage wires. The length of the high-voltage wires should be as short as possible, and the joints should be as few as possible. It is not allowed to wind or roll the high-voltage wires. If there are excess high-voltage wires, they should be cut off. And the high-pressure joints should be far away from metal and water pipes to avoid ignition of the high-pressure joints.


6. When the high-pressure glass bead or high-voltage wire joint of the laser tube ignites, the high-pressure glass bead or high-pressure joint should be reconnected. If there is oil stains at the connection, the oil stains must be cleaned up before reconnecting.


7. Keep the high-pressure end and high-pressure joints of the laser tube clean. If the high-pressure end and high-pressure joints are contaminated by oil and dust, it is easy to cause high-pressure ignition. Air pump and alcohol can be used to clean up pollutants regularly, and insulating materials can also be used for isolation treatment.


8. When the external voltage is unstable or lower than 210V, a voltage stabilizer can be installed or replaced with a stabilized laser power supply of the same model to avoid abnormal or inconsistent power of the laser tube due to unstable external power or low voltage. Stability and other phenomena.


9. No matter whether the laser tube enters from high pressure or low pressure, it will not affect the use of the laser tube, but it must be ensured that the water outlet of the laser tube body is vertically upward, and the installation is based on the principle of low inlet and high outlet. There is no obvious air bubble in the water-cooled tube .


10. The water inlet and outlet pipes of the laser tube should be far away from the laser tube body, especially the tube body of the laser tube light outlet (generally the temperature of the laser tube light outlet tube body is 40-60 ℃), to avoid condensation or excessive temperature of the water pipe low causes the outer tube of the laser tube to break.


11. Keep the laser tube window mirror clean and pollution-free. Clean up the contaminants of the laser tube window mirror with a bamboo cotton swab moistened with absolute ethanol (alcohol) regularly to prevent the laser tube window mirror pollution from affecting the laser tube spot and power.
