Abstract
An extruder welding shoe, preferably for a manual welding extruder that can be attached to an extruder nozzle of an extruder unit at the outlet side, with a material inlet, a material outlet, and a material flow channel extending in between these for a plastified plastic material that is to be extruded. The material flow channel has at least one material branch point that divides the material flow channel into material flow branch channels each of which has a material outlet. The extruder welding shoe includes an internally arranged air guidance system for the preheating air, with an air inlet, an air outlet, and an air flow channel connecting these. Preferably, the air flow channel has at least one air branch point that divides the air flow channel into air flow branch channels each of which has an air outlet. A manual welding extruder is equipped with an extruder welding shoe and is arranged on a chassis, preferably with spring suspension, that is driven. In addition, the manual welding extruder advantageously also includes an unwinding device for a plastic welding wire, preferably with a brake system.
