    • A compact plasma cutting apparatus suitable for the thermal cutting of concrete structures includes a sealed housing to which a plasma gas is fed under pressure. A metal strip that serves as an outer hollow electrode is bent such that a widthwise section thereof is in circular form, while a metal rod or tube is continuously inserted through a hollow portion of the thus formed outer electrode, with an insulator located between both electrodes. While gas is passed between the inner and outer electrodes, an arc is produced at open ends of both electrodes to generate a plasma gas, which is in turn blown onto a concrete structure for thermal cutting. The formation of both electrodes is effected depending on consumption of the electrodes, thereby carrying out thermal cutting continuously. A high-efficient yet economical cutting method is achieved using the cutting apparatus.
    • 适用于混凝土结构的热切割的小型等离子切割装置包括密封的壳体,等离子体气体在压力下被供给到该壳体。 用作外部中空电极的金属带被弯曲成宽度方向为圆形,而金属棒或管被连续插入穿过如此形成的外部电极的中空部分,绝缘体位于两个电极之间 。 当气体在内电极和外电极之间通过时,在两个电极的开口端处产生电弧,以产生等离子体气体,然后等离子体气体被吹到用于热切割的混凝土结构上。 两电极的形成取决于电极的消耗,从而连续进行热切割。 使用切割装置实现了高效且经济的切割方法。
