<p>The present invention concerns a welding torch apparatus, in particular a handheld welding torch apparatus with possibilities of weaving. The inventive apparatus comprises a nozzle (2) section for feeding of a welding wire to a workpiece during a welding operation and a handle section enabling handheld, manual operation of the welding torch apparatus during the welding operation, which handle section is attached to the nozzle section (2). The nozzle section (2) further comprises an elongated welding tip (4) displaying a channel (5) for the welding wire, wherein the channel (5) debouches at a free end of the welding tip (4) to enable feeding of the welding wire in a feed direction. The welding tip (4) of the apparatus is pivotally mounted in the nozzle section (2) in a joint (41-43) enabling the free end of the welding tip (4) to be pivoted about a first axis (x) and an orthogonal second axis. Furthermore, the welding torch apparatus comprises an actuator for actuating the welding tip (4) about the first axis (x) and the second axis enabling a movement of the free end along a first direction and along an orthogonal second direction, which first direction and second direction are orthogonal to the feed direction of the welding wire.</p> |
