摘要

PROBLEM TO BE SOLVED: To provide a plasma cutting machine and a cutting method capable of suppressing magnetic blow while suppressing a load on an operator and an influence on a material to be cut to be small.SOLUTION: A plasma cutting machine includes: an electrode for generating plasma arc; a nozzle having an opening where the plasma arc passes; and a cover member. The cover member is arranged so as to cover the nozzle in a jetting direction of the plasma arc from the nozzle. The cover member has an opening where the plasma arc passes. The cover member is made of a magnetic body.
