摘要：Cutting quality of the product, in particular, hole cutting quality, in plasma arccutting is improved. A control unit, which controls a plasma cutting apparatus for cuttinga product from a plate material by moving a plasma torch at a cutting speed along a
cutting path corresponding to the product shape to cut the plate material, whilesupplying an arc current and a plasma gas to the plasma torch and forming a plasma arcfrom a nozzle of the plasma torch to the plate material, conducts control so that, when ahole is cut, a cutting speed is lower, a value of the arc current value is smaller, and aplasma gas flow rate or pressure is less than those when a contour is cut.
