Abstract: An arc welding apparatus includes a conductor tube assembly that has a collar assembly with a collar body that is biased by a spring. A consumable assembly is mechanically secured to the conductor tube and displaces the collar body and the collar body imparts a biasing force against the consumable assembly pretensioning the consumable assembly on the conductor tube assembly.

Abstract: A nozzle assembly for a welding torch and a welding torch including said nozzle assembly is provided. The nozzle assembly generally comprises a base defining a distal threaded portion for securing the nozzle assembly to a distal end portion of a conductor tube of the welding torch, the base defining a distal threaded portion and a nose defining a mating threaded portion adapted to engage the distal threaded portion of the base, thereby removably securing the nose to the base. The distal threaded portion may comprise tapered Edison threads or a shell thread design.

Abstract: A nozzle assembly for a welding torch, a welding torch that includes said nozzle assembly, and a method of using the welding torch is provided. The nozzle assembly generally comprises an insulator having a plurality of grooves around an outer periphery, a plurality of sealing members disposed within the grooves of the insulator; and a nozzle body slip-fit around the insulator, such that at least one of the insulator and the nozzle body define position indicia.
