Abstract
The plasma torch has a nozzle and body. The nozzle has an inner nozzle and inner cap fastened to the body with the inner nozzle. Annular water passage and a plurality of independent water passages are formed between the inner nozzle and inner cap. Force applied when the inner cap is fastened to the nozzle base is transmitted via partitions. The torch body has a water supply port and drain port. At least one of the water supply port and drain port is configured as a groove extending on a plane crossing the axis and is connected to the water passage. When the nozzle is fastened to the torch body, one of the independent water passages communicates with the water supply port and another communicates with the water drain port. Rear end surface of inner nozzle is in contact with end surface of the nozzle base thereby obtaining electrical conductivity.
