The invention relates to a hand welding extruder comprising an inner channel from which the extrudate comes out, and a welding shoe (11) on the front end of the appliance, from which the melt product is discharged. The welding shoe can be fixed to a nozzle tube section (17). Especially a single-component plastic welding shoe is provided, which comprises both a front section forming a weld seam and a middle and/or rear section, to be fixed to the nozzle tube section. The means for fixing the welding shoe (11) to the nozzle tube section (17) preferably comprise a transversal rod (29) held at least partially in a radially inner groove of the welding shoe. As a result, the welding shoe (11) is applied to the nozzle tube section (17) first by sliding the welding shoe onto the nozzle tube section in the axial direction, and the welding shoe is fixed to the nozzle tube section following the rotation of the welding shoe in relation to the nozzle tube section. |
