Abstract
Abstract A welding head having a wire guide tube, through which a welding wire extends, located in and positioned longitudinally of a housing with its wire discharge and in alignment with a flux discharge opening provided in the housing. A plate, made of electrically insulating material, is slidably mounted on the housing and is connected to the wire guide tube for longitudinal adjustment of the nozzle to determine the amount of projection of the welding wire through the flux discharge opening. The plate includes a guide portion extending into an elongate slot formed in and arranged longitudinally of the housing, the guide portion cooperating with the slot margins to guide the plate, and hence the wire guide tube, longitudinally of the housing. Fastening means, made of an electrically insulating material, extends through an elongate hole formed in the plate and arranged longitudinally of the housing, the fastening means interconnecting the plate and housing to retain the plate in longitudinally adjusted positions. Pivot means mount the wire guide tube to the plate on a transverse axis, while wire guide tube-pivoting means selectively move the wire guide tube about the axis to adjust the position of the wire discharge end laterally of the flux discharge opening.
