Abstract: A torch wire feeder which includes a planetary feeder, an electrical motor and a handle. The feeder is characterized in that the electrical motor along with the planetary head is mounted to a back holder, and the goose-neck is mounted to a front holder, as the front and the back holders are assembled with the tubes for water-cooled and gas-cooled operation, as the back holder receives the wire from the conduit with holder thread nut. Furthermore, water tubes and a gas tube from the conduit are assembled to the back holder with a nut, and the front holder has distributor holes for gas and water cooling and also thread nut for transmitting the welding current, the water and the gas from the conduit to the neck, also contacting the holder to the thread nut with rubber seal, as all the parts are assembled to the handle with ergonomic form and also containing two potentiometers and start-stop switch and the hook, a all details and parts are included in ergonomic form body.

Abstract: A universal planetary feeder for feeding a wire which includes an elongate hollow body defining a wire feed axis and adapted for high speed rotation about the axis, and a pair of planetary rollers associated with the body so as to be rotatable together with the body about the feed axis and which are mounted about the feed axis in mutually skewed respective orientations. The planetary rollers define circumferential peripheral feed surfaces spaced from each other about the feed axis and are configured for simultaneous engagements with a wire along preselected lines of contact. Each of the feed surfaces is intersected at right angles by a plane which is offset from the feed axis by an offset angle.
