Abstract
A handheld extruder welding device is provided for welding thermoplastic synthetic materials by means of an extrusion screw with a feed zone and a conveying/plasticizing zone. In the area of the feed zone, a feed channel with a ridge running in longitudinal direction is located in a sleeve. This ridge prevents the inserted plastic welding wire from twisting and looping inside and especially outside the handheld extruder welding device.
