An apparatus for positioning a workpiece in a desired orientation for welding or the like during a manufacturing process is provided. The positioner has a generally vertical support column and a generally horizontal boom which is pivotally coupled to a top end of the support column. At a second end of the boom, the positioner has an arm member with a rotatable shaft extending therefrom upon which a workpiece may be mounted. The column is preferably mounted on a turntable such that the positioner may be rotated about a longitudinal axis of the column. In use, the positioner can move a workpiece up, down, left, right and to and fro to change the location of the workpiece. The orientation of the workpiece may also be changed by rotating the workpiece about a longitudinal axis of the shaft.
