Beschreibung
Zusammenfassung:	A contact tube of a welding torch nozzle is constituted in its front part by a contact nozzle (4) with a straight guide duct (17) and in its rear part by a guide tube (3) the inside diameter of which is greater than the diameter of the guide duct (17). The guide tube (3) is provided on its inside with one or two projections (11, 12) which force the electrode during its passage through the guide tube (3) to changes in direction. In the process, the electrode will be slightly curved before it enters the guide duct (17) where the curvature is straightened out, thereby establishing good contact with the contact nozzle. The electrode is straight when it leaves the contact nozzle. The contact tube is particularly suitable for electrodes with a diameter less than 1.6 mm.
