Abstract
A method and apparatus for using a collet to align and/or axially secure a liner within the gooseneck of a welding torch and to extend the useful life of the torch components are provided. A method and apparatus for securing torch components including said collet and including tapered locking engagement connections are also provided. A position of the liner with respect to a retaining head or a diffuser can be established and maintained, in spite of bending, swiveling, and other general movement of the torch, while still allowing flow of a shield gas past the collet. The welding torch components, including a gas diffuser, can be secured to the torch or other torch components via tapered locking engagements. The invention is useful for both manual and robotic torch systems.
