This series of products is a new generation of heat cutting equipment. Lt fully utilizes the characteristics of high temperature, high energy, high density and high seppd of plasma arc, makes the metal material in cutting area to be rapidly molten and to be blown away from the base body by means of common compressed air, accomplishes the cutting process. Ln addition to its cutting function of oxygen acetylene, it can also make arbitrary cutting for the nonferrous metals such as stainless steel, aluminum, coper and cast iron etc, lt has the advantages; Lts cutout is narrow; Cutting speed is high; Without heat deformation, and so on.
