    摘要： [PROBLEMS] To reduce the generation of fume in cutting a material to be cut typified by a steel plate with plasma.
    [MEANS FOR SOLVING PROBLEMS] A plasma cutting method comprising spraying a plasma arc directed through a material to be cut from a plasma torch nozzle to cut the cutting material, wherein a plasma arc formed by supplying a mixed gas as a plasma gas composed of a single gas or a plurality of gases selected from halogen gases and rare gases belonging to up to the second row elements of the periodic table and a hydrogen gas, and oxygen-, argon- or nitrogen-containing gas to a part around an electrode, and electrifying a part between the electrode and the nozzle or between the electrode and the cutting material is sprayed toward the cutting material to cut the cutting material, or wherein a single gas or a plurality of gases selected from halogen gases or rare gases belonging to up to the second row elements of the periodic table and a hydrogen gas, together with the plasma arc composed mainly of an oxygen, argon or nitrogen gas, is sprayed toward the cutting material to cut the cutting material.
