Adjust the light point to meet your engraving and cutting requirements for more precise results. When stainless steel is heated by an ultra-intense laser beam, a physical reaction occurs on the metal surface, creating hundreds of colors that bring your workpiece to life. Manually adjust the air assist continuously using the knob, or automatically adapt the airflow through the LightBurn software to different engraving and cutting needs. This removes smoke and dust during the engraving or cutting process and protects the lens of the laser head, ensuring that the edges of the workpiece remain clean.
