The power of the CO2 laser tube degrades over time.
You can try the following methods to improve the performance of the cutting process: increase the power, lower the speed, and increase the processing pass.
If the power drops drastically, please replace the laser tube.
#6 Set a Higher Airflow Value
Please go to Settings to adjust the Airflow of the air pump to 100% in Cut mode.
#7 Check the Focal Lens Installation
When the focal lens is not installed properly, the laser spot will become larger, decreasing cutting performance.
