The invention relates to a heating element () for liquids to be vaporized as well as a burner () of a steam cutting device () and a burner () of a power-generating device, the element being designed as an induction heater () comprising one coil (). In order to improve vaporization, the coil () of the induction heater () is enclosed in a hybrid construction which is composed of a main part () with laterally extending webs (), and which consists of an easily magnetizable material () and a thermally highly-conductive material, a covering element () consisting of nanocrystalline materials being arranged on the webs (), and the easily magnetizable material () being designed to be installed on a thermally highly-conductive material () of a vaporizer ().

For a WIG/TIG welding torch, gas distribution across a cross-section of the gas lens and/or the gas nozzle, is improved and as small a size and as low a weight of the components as possible can be achieved, when an insertion element with a bore in the center through which an electrode is to be guided is arranged, with fan-shaped flow elements being positioned around the bore and twisted relative to the plane of the bore so as to provide for radial deviation of a gas flowing therethrough. The gas lens consists of a base body having a gas distribution channel with at least one gas-lens filter, with an above-described insertion element being arranged in the gas-distribution channel, and with a gas-lens filter, seen in the out-flow direction of the gas, being arranged downstream of the insertion element.

The invention relates to a securing element () arranged between a gas element () and a current element () of the plug-in element (). A fixing element () is arranged in the coupling () of the torch handle and meshes with said securing element (), and, for guiding over said fixing element () arranged in the coupling (), the gas element () has a diameter smaller than those of the securing element () and of the current element (). Said securing element () can be guided over the fixing element () using a flat area (), while the gas element () is arranged in a gas bore hole () in the coupling () in a sealing manner. The position of the torch body () can be freely adjusted by means of a manual rotational movement, said fixing element () being guided in a circumferential groove () in said securing element ().

The invention describes a method for welding a workpiece () with a consuming welding wire (), the latter being moved substantially towards the workpiece () by a wire feeder () during a welding process, wherein a process is started and performed for removing slag () from the end of the welding wire (). In order to create a welding method which is not affected by slag () possibly adhering to the end of the welding wire () to be contacted and which ensures a safe ignition of the electric arc (), it is provided that the welding current (I) will be reduced to a minimum value as soon as the slag-removing process is started, and during the slag-removing process, that the welding wire () will be cyclically moved towards the workpiece () by a predetermined path length in a fast recurrent forward/backward movement and will again be moved away from the workpiece () by a smaller path length until short-circuit detection between the welding () and the workpiece (), by a short-circuit monitoring unit upon which the slag-removing process will be finished.
