3. Air Assist Function
The integrated air assist kit significantly improves cutting and engraving quality.
- Enhanced Cutting: The adjustable airflow (10-30L/min) suppresses smoke and dust, preventing laser energy attenuation and ensuring cleaner, smoother edges.
- Reduced Yellowing: Air assist helps prevent charring and yellowing on materials during laser processing, especially for wood and acrylic.
