1. A method of assembling a multi-piece cartridge consumable comprising an outer component and an inner component for installation into a plasma arc torch, the method comprising:
disposing the inner component within a hollow body of the outer component;
axially securing the outer component relative to a forward portion of the inner component, the axially securing comprising:
restraining a longitudinal motion of the outer component relative to the inner component; and
enabling independent rotation of the inner and outer components relative to each other while the outer component is axially restrained relative to the inner component, such that the outer component is adapted to be rotated relative to the inner component for engaging a torch head; and
substantially suspending and radially orienting, by the axial securing, a rear portion of the inner component within the hollow body of the outer component.
