CO2 Laser Tubes

CO₂ laser tubes operate in cycles that gradually affect their performance over time – reduced power, deteriorating cut-edge quality or the need to reduce speed or make multiple passes are typical signs of wear. Correct selection and installation of a new tube, combined with stable cooling, help maintain repeatable quality and minimise downtime.

What to consider when choosing a tube:

• Power and application – match the tube to the materials being processed and the planned workload, whether for series production or prototyping.
• Compatibility – check the length, diameter, connection method and electrical and mechanical compatibility with your machine model.
• Cooling – match the tube to the capacity of the chiller and maintain a stable coolant temperature within the recommended range.
• Operating conditions – a clean, well-ventilated workspace and suitable ambient temperature help maintain stable performance.
• Installation and alignment – precise positioning and checking the optical path help reduce power losses and improve cut-edge quality.

Operation and maintenance:

• Regularly check the condition and level of the coolant, the flow through the cooling circuit and the tightness of all connections.
• After replacing the tube, carry out calibration and test cuts on reference materials, and record the process parameters to ensure repeatability.
• Plan preventive maintenance – it is a simple way to extend component service life and maintain predictable production.
