The invention relates to a positioning device (203) for a manual welding machine (300), particularly for a plastic welding machine, comprising at least one contact shield (16) associated with the manual welding machine (300) and a positioning ring (3) associated with the material to be welded. In order to perform precise welding and to prevent the subsequent slipping of the manual welding machine (300), according to the invention, the positioning ring (3) can be fixed to the material to be welded and a contact shield (16) that can be inserted in the positioning ring (3) transfers a pressure distributed evenly over the circumference to the materials to be welded, in order to allow secure welding over a large area. |
