Abstract
Handheld extruder welding device for welding thermoplastic synthetic materials, including an extruder screw, a drive system for the extruder screw in an axial extension of the extruder screw, and a hot air unit with a blower, where the blower and the drive system are integrated in a housing including several parts, and where a cooling body with air inlets is located on the housing on the screw side. This cooling body transfers the axial and radial forces between the drive system and the screw cylinder and supports the housing. In this handheld extruder welding device, all drive components are integrated in one housing which makes it suitable for robust use and a long service life. Its design with a cooling body as the support base for the entire device represents a special function.
