When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
