<p>The invention relates to a wire advancing device for conveying a wire, particularly a welding rod, from a wire supply to a useful point with the aid of conveying means. The wire advancing device comprises a mechanism for adjusting the contact pressure applied to the welding rod by the conveying means. In order to create a wire advancing device which is provided with little slip and can be used for welding rods that have a different diameter and are made of different material, the adjusting mechanism encompasses at least one elastically or plastically deformable pressing means which acts upon the conveying means and is connected to a supply unit. The pressing means is filled with a gaseous or liquid medium via the supply unit in order to adjust the contact pressure applied to the welding rod by the conveying means.</p> |
