Abstract: The invention concerns a gas lens housing (20) for arc-welding or flame cutters with a non-melting electrode (4), in particular for T.I.G. welding. According to the invention, a torch member (1) comprises a housing (2) for accommodating an electrode holder (3) which optionally comprises in a front, downstream section (26) collets (28) with expansion slots (8) for clamping the electrode (4) in place. An annular duct (24) used as a protective gas duct is formed between the electrode holder (3) and a housing casing (22) and a gas lens (6) is disposed in the annular duct (24) or torch nozzle (5). The gas lens housing (20) is mounted with play at a front end (30) of the electrode holder (3).

Abstract: The specification relates to a burner holder for a mechanized or automated welding or cutting device, e.g. machine or robot burner (2). In order to be able easily, reliably and especially reproducibly to insert the burner at a predetermined point, the burner (2) is releasably held between two clamping jaws (3, 4) which grip the burner (2) at least in areas of the periphery and at least one of which can be moved between an open and a closed position.

Abstract: The cable connection includes a connecting piece connected with an end of a cable for electric arc welding or electric arc cutting. An end piece is joined with the connecting piece while a coupling is joined with the end piece. Thus, a relatively smaller inventory of cables which are provided with connecting pieces may be warehoused and a particular cable may be adapted to an application with a particular electric arc welding machine, electric arc cutting machine, and electric arc tool by selection of the appropriate end piece and coupling to be joined with the connecting piece at each end of the cable.

Abstract: An arc welding or cutting torch includes a torch body, a jacket encased within the torch body, an electrode holder encased within the jacket and a heat dissipater interposed between the electrode holder and the jacket. The heat dissipater is made of a material with a greater thermal conductivity than the material forming the electrode holder.

Abstract: An arc welding or cutting torch has a torch body with a torch nozzle and a housing having a taper fit lock for an electrode holder. The housing includes a tapered bore section and a cylindrical bore section disposed rearwardly of the tapered bore section. An electrode holder has a frustoconical portion with rearwardly facing tapered surfaces which engage the tapered section of the housing and a cylindrical portion disposed rearwardly adjacent the frustoconical portion and engaging the cylindrical bore section of the holder.

Abstract: Drive device for continuously consumable wire electrodes of electric welding torches, comprising a wire drive roller 5 arranged in a housing 1 having a handle 2 and a drive motor acting on the wire drive roller 5 via gearing 6 and arranged outside the wire feed axis, the drive unit consisting of drive motor 4, gearing 6 and wire drive roller 5 being arranged in a housing part 3 formed outside the area of the handle 2 enclosed by the hand. The consumable wire electrode and the supply lines are passing through the handle 2, and the motor shaft 10 of the drive motor 4 is arranged at right angles to the wire feed axis 8.
