ABSTRACT:
The flexible wire guide assembly of the torch is located between the torch body and the nozzle assembly and includes at least two layers of helically wound multi-strand conductor circumferentially arranged in concentric relation to form an annular passageway for a moving electrode. The layers are contained within an inner and outer extension spring which cooperate during the application of a bending force to restrain the layers from bulging inwardly or outwardly respectively. The outer spring is held in lateral compression with its turns spaced a predetermined distance apart.
