When cutting, the torch nozzle and the workpiece are kept at a distance of 2 to 5 mm, and the nozzle axis is perpendicular to the surface of the workpiece, and cutting is started from the edge of the workpiece. When the thickness of the plate is 12 mm,It is also possible to start cutting at any point of the workpiece (using a current of 80A or more), but when piercing the middle of the workpiece, the torch should be tilted slightly to one side in order to blow off the molten metal.Users are advised to avoid piercing and cutting as much as possible. Because the molten iron that is reversed during perforation adheres to the nozzle, the service life of the nozzle is reduced, which greatly increases the cost of use.The thickness of the perforation is generally about 0.4 of the thickness of the cut.
