Abstract
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.
