Abstract
The invention relates to a device and a method for contacting a welding wire () in a welding torch (), including at least two contact shells () having a contact area () for contacting the welding wire (), and to a contact shell () for contacting a welding wire (). In order to make the contact of the welding wire as constant and permanent as possible during the lifetime of a contacting device, the contact shells () have a holding section () and are arranged inside a sleeve () to define a rotational axis (), the sleeve () being fastened to a nozzle pipe () having an integrated pressure mechanism (), and the pressure mechanism () being adapted to exert pressure () on the contact shells (). The sleeve () includes a holding device () for exerting a counter-force () onto the contact shells (). The welding wire () is contacted in the contact area () of the contact shells () with a contact force ().
