Apparatus for the planetary feeding of electrode wire having means for adjusting the pushing force exerted on the electrode wire by electromagnetic means. Opposed canted rolls are mounted for rotation about their axes upon a first housing part which is rotatable about the axis of an elongated electrode wire which passes between and is fed by the canted rolls. A second housing part, which is disposed coaxially of the first housing part, bears means such as a cam or a cone which interacts with roll adjusting means mounted on the first housing part so as to adjust the force with which the canted rolls engage the electrode wire in accordance with relative motion between the two housing parts. The second housing part is driven for rotation about its axis. The degree of motion of the two housing parts relative to each other, thereby to vary the force with which the canted rolls engage the electrode wire, is determined by an externally controlled electromagnetic means which can be adjusted while the welding apparatus is in continuous operation.
An apparatus for the planetary feeding of electrode wire, comprising a housing, means for mounting the housing for rotation about its axis, opposed canted rolls mounted on the housing on opposite sides of the axis of the housing for engaging and feeding electrode wire along the axis of the housing, means movable relative to the housing for adjusting the force with which the rolls engage the electrode wire, means for rotating the housing about its axis, and means including an electromagnetic coil and an element variably responsive to variations in the magnetic field produced by the energization of the coil for moving the adjusting means to adjust the force with which the rolls engage the electrode wire.
