The planetary driven welding-wire feed device with elastic pressure-force transmission is used in the MIG/MAG welding technique for the simultaneous welding-wire feed. It consists of a body (1) onto which a clamping device (2), which transmits the force via a disc spring (3) and a ring (4) to a jaw pair (5), is screwed and to the opposite side of which body drive wheels (6) are attached. The distance and the pressure force between the drive wheels (6) is set by tightening or unscrewing the clamping device (2). As a result of the inserted disc springs (3), the planetary drive mechanism functions elastically, and any overloading of the construction during the setting is thereby prevented. <IMAGE>
