An adjustable slip-fit welding nozzle enables very fine adjustments to be made to the dimensional relationship between a nozzle orifice and a welding contact tip of a wire welding gun. The welding contact tip is screwed into a tubular adapter that is stationarily joined to the welding gun. The adapter has a stop that extends radially therefrom. The nozzle is part of an extension assembly that is rotatable on the adapter. The extension assembly includes an insert with an end that is at an oblique angle to the adapter longitudinal axis. By rotating the extension assembly on the adapter while holding the insert angled end against the stop, the extension assembly and thus the nozzle orifice reciprocate relative to the welding contact tip. The extension assembly is rotated on the adapter until the nozzle orifice is at a desired dimensional relationship with the welding contact tip. The extension assembly is comprised of a tubular sleeve, insulator, and insert. The three components are assembled together into a unitary extension assembly by radially swaging the sleeve to the insulator and the insulator to the insert.
