[BENEFITS OF AIR ASSIST]
-Prevents smoke from degrading cutting power.
-Clears some of the debris/charred material that has been cut from the cutting line which is useful if doing multiple passes.
-Reduces the risk of material catching on fire.
-Keeps debris and vaporized material from depositing on the lens of the laser.
