Abstract
The invention relates to a securing element (30) arranged between a gas element (32) and a current element (33) of the plug-in element (28). A fixing element (34) is arranged in the coupling (29) of the torch handle and meshes with said securing element (30), and, for guiding over said fixing element (34) arranged in the coupling (29), the gas element (32) has a diameter smaller than those of the securing element (30) and of the current element (33). Said securing element (30) can be guided over the fixing element (34) using a flat area (35), while the gas element (32) is arranged in a gas bore hole (37) in the coupling (29) in a sealing manner. The position of the torch body (27) can be freely adjusted by means of a manual rotational movement, said fixing element (34) being guided in a circumferential groove (36) in said securing element (30).
