holder because of this design the inert gas is exposed to windup and is carried out of the gas lens which has been shown to be advantageous for stabilizing the arc this measure specifically prevents the arc from wandering it is of course understood with the last mentioned model that the gas lens housing is designed in such a way that it can rotate freely around the longitudinal axis of the electrode holder even when the electrode is fastened in the electrode holder in an advantageous model of the invention the holding element is fastened on the interior side wall of the outer part with an initial ring step ring nut or the like in order to achieve a further equalization of the inert gas volume flowing from the gas lens there is a second ring step ring nut or the like in downstream direction of the first ring step in which one or several sieves are able to be locked or fastened beyond that it has been proven advantageous for the sieve s to be able to be locked or fastened with a central bore in a ring nut or the like of a jacket section of the holding element this holds the normally quite flexible sieve s securely and permanently in the gas lens housing other advantages and application possibilities of the present invention arise from the subsequent description of a design model with the aid of the drawings fig1 a wig torch with an electrode holder with a collet chuck and with a gas lens that is attached with play fig2 the electrode holder with attached gas lens according to fig1 fig3 a cutaway representation.
