Abstract:
1. A plasma arc torch, comprising: a first consumable component, said consumable component having a longitudinally extending connection end; a second component in a coaxial relationship with said first consumable component, said second component having a bore defined therein into which said longitudinally extending connection end extends, said bore including a contact surface defined substantially perpendicular to a longitudinal axis of said torch; said longitudinally extending connection end of said first consumable component comprising a contact shoulder defined substantially perpendicular to the longitudinal axis of said torch, a locking engagement section configured to engage with said second component and draw said contact shoulder against said contact surface of said second component, and an alignment section extending longitudinally from said engagement section; and said alignment section having a diameter closely matching that of said bore such that substantially any degree of axial misalignment between said first consumable component and said second component is due to dimensional machining tolerances between an outer circumferential surface of said alignment section and an inner circumferential surface of said bore.
