  • Patent number: 4739147
    Abstract: An improved pre-aligned demountable plasma torch wherein the three tubes that are generally used in demountable plasma torches are now joined together with standard taper joints. The axis of the standard taper joints are essentially centrally aligned with the central long axis of the tubes so that the tubes are pre-aligned and essentially concentric in the assembled torch. If any of the tubes becomes damaged in use they can be replaced with a similarly constructed tube with a minimum of interruption and expense, without the need to adjust the tubes to be essentially concentric and in an assembly consisting of only 3 parts.
