    摘要： A liquid-cooled consumable cartridge for a plasma arc torch is provided. The cartridge includes (i) an electrode, (ii) a swirl ring with a first outer retaining feature and a second outer retaining feature on an exterior surface, where the electrode is secured to the swirl ring, and (iii) a nozzle with an inner retaining feature on an interior surface, where the inner retaining feature of the nozzle is mated with the first outer retaining feature of the swirl ring. The cartridge also includes a cartridge frame with an inner retaining feature on an interior surface and an outer retaining feature on an exterior surface. The inner retaining feature of the cartridge frame is mated with the second outer retaining feature of the swirl ring. The cartridge further includes a shield with an inner retaining feature on an interior surface mated with the outer retaining feature of the cartridge frame.

    摘要： A front end assembly for a plasma torch and methods for assembling and disassembling a torch wherein a plurality of front end parts form a unit that is removable from, and installable in, the torch in a single operation without a special fixture. The front end assembly includes a nozzle retaining cup body connectable to a body of the torch, and a forward end connectable to a shield retainer. A nozzle retaining cup insert fits into the nozzle retaining cup body. The shield retainer has an inner surface for retaining the shield. A nozzle is received within the nozzle retaining cup insert. A stop on the nozzle engages the nozzle retaining cup insert when the front end assembly is removed from the torch so the nozzle does not remain in the torch. The shield engages an insulator, which engages the nozzle, to limit forward axial movement of the nozzle.

    摘要翻译： 一种用于等离子体焰炬的前端组件以及用于组装和拆卸割炬的方法，其中多个前端部件形成一个单元，该单元可在没有特殊固定装置的情况下以单一操作移除和安装在割炬上。 前端组件包括可连接到手电筒主体的喷嘴保持杯体，以及可连接到护罩固定器的前端。 喷嘴保持杯插入件装配到喷嘴保持杯体中。 屏蔽保持器具有用于保持屏蔽的内表面。 喷嘴保持杯插入件内容纳喷嘴。 当前端组件从割炬中取出时，喷嘴上的止动件与喷嘴保持杯插入件接合，因此喷嘴不会保留在割炬中。 屏蔽件接合与喷嘴接合的绝缘体，以限制喷嘴的向前轴向运动。
