ABSTRACT:
A planetary wire feeder for feeding wire workpieces such as welding wire for a MIG or TIG welding operation comprises two sets of rollers connected to rotate in unison about the axis of the wire and radially spaced from each other in a housing. Roller holders have an axially tapered outer surface and are axially movable within the housing. Stationary gibs mounted within the housing with complementary tapered surfaces adjust the spacing between the roller holders at different axial positions of the roller holders within the housing. A nipple is provided on one roller holder tapered outer surface to equalize the pressure of each set of rollers on the wire.
