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). Adjusting knobs (290) engaging a portion of the screw (280) extending through the opening adjust the length of the screw between the gimbal (275) and the arm (285).
