Abstract: An apparatus (105) and method are provided for feeding wire (135) to a tip (120) of a torch (115) in a welding system (100). The apparatus (105) includes a drive mechanism (150) attached to the torch (115), and a guide assembly (155) attached to the drive mechanism. The guide assembly (155) includes a bracket (180) by which it is attached to the drive mechanism (150), a wire guide (185) through which the wire (135) is passed, and first and second adjustors (270A, 270B) to position the wire guide relative to the tip (120). The guide assembly (155) is configured to pass the wire (135) in a straight line from the drive mechanism (150) to the tip (120). In one embodiment, the adjustors (270A, 270B) include gimbals (275) supporting the wire guide (185). Each gimbal (275) is attached to a screw (280) passing through an opening in an arm (285) projecting from the bracket (180) of the guide assembly (155).

Abstract: A gas shielding apparatus for shielding a weld with a gaseous substance. The gas shielding apparatus includes a shroud body mountable to a torch body having a first plenum for producing a primary shield stream and a first delivery structure for delivering the gaseous substance to the first plenum. The shroud body has a second plenum defining a secondary shield stream substantially surrounding the primary shield stream. A trailer shield portion extends laterally from the shroud body and has a second plenum for producing a trailer shield stream. The apparatus also includes a second delivery structure for delivering measured amounts of the gaseous substance from the first delivery structure to the second plenum and the third plenum. The second delivery structure is coupled to the first delivery structure upstream from the primary plenum when the shroud body is mounted to the torch body.
