The device comprises a carriage guide (5), a carriage (6), which is displaceably and linearly mounted on the carriage guide along a carriage axis, an advancement drive, which has an advancement device that is provided and driven on the carriage to induce an advancement movement of a welding wire, and a carriage drive, which includes a drive, an eccentric (10) that is driven by the drive and an eccentric rod. The eccentric rod is eccentrically mounted on the eccentric, and is mechanically coupled to the carriage for a reciprocating carriage movement. The device comprises a carriage guide (5), a carriage (6), which is displaceably and linearly mounted on the carriage guide along a carriage axis, an advancement drive, which has an advancement device that is provided and driven on the carriage to induce an advancement movement of a welding wire, and a carriage drive, which includes a drive, an eccentric (10) that is driven by the drive and an eccentric rod. The eccentric rod is eccentrically mounted on the eccentric, and is mechanically coupled to the carriage for a reciprocating carriage movement. The carriage drive has a unit for adjusting the travel of the reciprocating movement of the carriage, and a guide as the unit for adjusting the travel of the reciprocating carriage movement. The guide displaceably bears at the eccentric on a guide axis that runs at an incline to the carriage axis of the carriage guide. The drive and the eccentric form a module. A shaft of the linear guide passes perpendicular to the carriage axis of carriage guide. The drive further includes a motor and a belt drive connected to the motor. The belt is further connected to the eccentric, and is designed as a toothed belt, which is engaged with a toothing of the eccentric. The eccentric rod has an adjustable length. The device further comprises a support (4) on which the carriage guide and the guide are attached. The support is attached to the motor, and is provided on the carriage. The carriage provided is drive-connected to the advancement device. The motor is drive-connected with the advancement device the belt drive. The belt drive comprises a tension roller. The advancement device includes a pair of pinch rollers for guiding the welding wire. |
