Abstract
The present invention relates to a welding torch that includes an electrode () that has a longitudinal groove () formed therein which guides a welding wire () which is fed form a laterally spaced-apart location. The electrode () is open and the wire () is supported on one side only. In the region of the welding tip, the electrode () is elongate and the cross-sectional area is smaller than the area at a position further from the tip. Regions between an outer housing () and a main support body () define two shielding gas conduits positioned on opposite sides of the body (), through which gas flows and then combines to form a unitary stream. The body () contains cooled regions which are supplied with cooling fluid by a conduit () and removed by conduit (), parts of which are positioned between the shielding gas conduits close to the welding electrode ().
