<p>The welding torch comprises a device (10) for welding wire feed, which consists of a tube (4) with a discharge opening (3) ending in the welding zone for welding wire (2) and a holder (5). The device is led movable to the welding wire feed with respect to the welding torch. For guiding, a link and two guidance elements cooperating with the link are intended at the device and at the welding torch, so that the discharge opening of the pipe is movable from the welding zone. The holder has the guidance elements interfering into the link. The welding torch comprises a device (10) for welding wire feed, which consists of a tube (4) with a discharge opening (3) ending in the welding zone for welding wire (2) and a holder (5). The device is led movable to the welding wire feed with respect to the welding torch. For guiding, a link and two guidance elements cooperating with the link are intended at the device and at the welding torch, so that the discharge opening of the pipe is movable from the welding zone. The holder has the guidance elements interfering into the link. At the welding torch on both sides of the holder, a guidance part forming the link is intended. A front- and a rear guidance element are intended on the both side of the holder. The link is so carried out that the discharge opening removes from the welding zone and then moves into rear direction. The link has a part for the guidance of the rear guidance elements running towards the axis and an initially raising part for the guidance of the front guidance elements. For the movement of the device an actuator is intended, which attacks on this device and on the welding torch.</p> |
