Extruder welding device

Abstract

The invention relates to a hand welding extruder (1) for welding thermoplastic materials by means of a plasticized plastic strand (26) having a plasticization worm unit (24) connected to a drive motor (20) by a gearbox (21), and having a hot air generation device (27) with an external air supply, the plasticizer worm unit, the gearbox, the drive motor, and the hot air generation device being disposed in a common housing. The proposed hand welding extruder has a bar-shaped housing having a front welding segment (7) and a grab handle (8) connected thereto in the longitudinal direction. The plasticizer worm unit and the hot air generation device are disposed in the bar-shaped housing in the welding segment and an electric motor (20) is disposed in the grab handle. The electric motor is connected to a shaft of the extruder worm (23) via a gearbox, the gearbox being potentially provided in the grab handle and/or the welding segment of the bar-shaped housing of the hand weld extruder.
