    Abstract: A power transfer assembly for a contact-start plasma arc torch conducts electrical current to an electrode through mating structures provided on two conductive elements. The mating structures are defined by sidewalls that are parallel to an assembly axis, and are configured to translatably engage each other, but are blocked from rotating with respect to each other. A compression and torsion spring serves to bias the conductive elements apart to bias the electrode to a forward position, and to apply a torsional load to the mating structures to maintain their sidewalls in contact. The mating structures can be provided by a shaped recess in one conductive element and a corresponding shaped protrusion extending from the other element. The spring can be secured to the conductive elements to maintain the components of the power transfer assembly together when the torch in which they are employed is disassembled.

    Abstract: A contact start plasma torch has a shuttle element disposed between a cathodic component and an anodic component. The shuttle element is movable between a first position and a second position and is maintained in the first position during an idle mode and a cutting mode. When the shuttle element is in the first position, a separation is maintained between the cathodic component and the anodic component of the plasma torch. The shuttle element momentarily bridgingly connects the cathodic component and the anodic component when it is located in the second position and initiates a plasma arc therebetween as it returns to the first position.

    Abstract: A translatable nozzle is supported in a contact start plasma arc torch at an aft end by a swirl ring and at a longitudinally spaced forward end by an insulative bearing member of a nozzle retainer. The nozzle is biased into contact with an electrode by a compliant spring element. A pilot arc is formed by first passing current through the electrode and nozzle. Upon pressurization of a plasma chamber formed therebetween, the nozzle is translated forward, compressing the spring element and initiating the pilot arc. The spring element may be maintained integrally with the nozzle to facilitate removal and replacement of the spring element with the consumable nozzle.
