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).
