MCWlaser CO2 Laser Tube 40W 50W 60W 80W 100W 130W 150W 180W For Laser Engraving & Cutting Machine Universal Model

The product quality of laser tubes mainly depends on laser power, spot quality, stability and service life.

1). Matching power supply, appropriate working current, and good water cooling
2). Current setting and laser tube life
The appropriate current will not only keep your laser tube in a stable processing state, but also make the service life of the laser tube longer.
Current settings of commonly used power laser tubes
Laser tube power ≤80W, current generally ≤20mA
Laser tube power 80W ~100W, current generally ≤25mA
Laser tube power ≥100W, current generally ≤30mA
3) Laser tube and power supply
It is recommended that laser tubes of different powers be matched with matching laser power supplies, blindly increase the current or use a higher power laser power supply. Excessive current will not only increase the burden on the cooling system, but also cause the laser tube to consume gas faster. Accelerate the aging of the laser tube and reduce its service life.

It is recommended to use deionized water or distilled water as the cooling water type. If tap water is used as cooling water for a long time, impurities in the laser water pipe will adhere and turn black, and even affect the water flow rate.

Pay attention to the order of the laser tubes. Make sure to turn on the cold water before turning on the laser power. Otherwise, the laser tube will become hot and break, making it unusable. In addition, make sure that the water pipe is full of water and there are large bubbles before turning on the laser power. There are bubbles in the water pipe, that is, air has entered, and with the increase in temperature, it is easy to cause the laser tube to burst; the return pipe of the cooling water is also It should be lower than the water surface, otherwise the filling may not be full next time; the water flow rate should be controlled at 2L-4L/min.

a. It is necessary to ensure the operating environment of the laser processing equipment, and the power supply voltage must be kept stable. If the voltage fluctuation is too large, configure a regulated power supply;
b. The laser processing equipment must be placed stably and cannot work in an environment with large vibrations or moisture (humidity can easily cause high-pressure sparks);
c. The laser current should not be too large, and the light intensity should be reduced as much as possible to meet the processing requirements and speed;
d. It is necessary to ensure that the laser tube has enough circulating water (temperature between 5-25°C), clean and free of debris, and replace the circulating water regularly, preferably deionized water or distilled water;
e. Finally, wipe the focusing lens from time to time to keep it clean.

a. Avoid ignition of the high-voltage terminal electrode, avoid accumulation of dust and metal near the high-voltage terminal, keep the high-voltage terminal dry, remove all conductive and flammable items, and keep them as far away from the metal cover of the machine as possible.
b. Check the sealing effect of the high-voltage end. After putting on the high-voltage cap, fill and seal with insulating glue or glass glue.

During testing and operation, the maximum current used for normal cutting of all models is 35mA. It is recommended to use a current of 20-30mA (increase the current by 3-5mA when the room temperature is lower than 15 degrees). Excessive current will increase the gas consumption rate and reduce the laser tube's performance. Lifespan is reduced.

Please note during work that smoke will inevitably splash onto the output surface during work. It is best to install a smoke removal device and wipe the lens regularly. Use a cotton swab specially designed for the lens dipped in absolute ethanol to wipe it.

There are the following reasons: 1. The water level switch is broken; 2. The high-voltage line is interrupted; 3. The laser tube is broken or burned; 4. The laser power supply is broken; 5. No water circulation, including the water pipe is blocked and the water pump does not work; 6. Water protection The wire is broken or the contact is not good; 7. The laser power supply voltage is less than 220V; 8. There is no signal from the laser power supply; 9. The online two-axis card is broken.

a. The laser tube is burned out or the laser tube light fails;
b. Reflectors and lenses need to be replaced;
c. Dust adheres to the front lens of the laser tube, causing the lens to burn;
c. The optical path of the laser tube is incorrect;
d. The materials processed are incorrect (less than 60W is generally used for engraving, and above 60W is used for cutting. Laser tubes with different powers cut different materials);
e. The tube has been used for too long, and the power of the laser tube is normally attenuated (not covered by the warranty).
