Abstract
A contact tip for hot-wire welder is provided that are adapted to operate in deep and narrow recessed gaps within a work piece. Contact tips in accordance with the current invention provide for an assembly having a body portion with a cavity and an extension portion which is inserted into the cavity. The extension portion is non-electrically conductive and allows the contact tip assembly to reach into deep, narrow grooves without worry of shorting the contact tip of the consumable.
