CO2 Laser Tube

A CO2 laser tube is the key component of a CO2 laser machine, used to cut and engrave non-metal materials like wood, acrylic, leather, and glass. It generates a focused infrared laser beam by exciting a CO2 gas mixture with high voltage. There are two main types: glass tubes, which are cost-effective and commonly used for standard engraving and cutting; and metal tubes, which offer longer lifespan, higher stability, and faster pulse response, but are more expensive.

How to Choose the Right CO2 Laser Tube?

Select based on power and application:

• 20W–60W: Light engraving
• 80W–500W: Thicker material cutting
  

Check compatibility with your machine, and choose trusted brands for better lifespan and consistent output.

How to Replace a CO2 Laser Tube?

• Turn off and unplug the machine
• Disconnect water and power lines from the old tube
• Install and connect the new tube
• Align the laser beam using mirrors
• Test at low power
• Secure all parts before regular use

A properly selected and installed CO2 laser tube ensures stable performance and high-quality results in your daily laser work.
