    Abstract: A wire feeder includes a wire feeder housing that may enclose one or more drive rollers rotatably connected with respect to the wire feeder housing for engaging welding wire. The one or more drive rollers may be adjustable and adapted to drive the welding wire to a welding gun connected to the wire feeder. A drive motor is incorporated for delivering power for rotating the one or more drive rollers. Friction reducing devices, such as bearings, may be utilized and positioned between one or more driver rollers and the housing, where the bearings are electrically non-conducting for preventing the discharge of electrical energy across the bearing surfaces.
