Abstract
A protective gas nozzle (6) and a gas feed channel (10) for the protective gas is arranged concentric around a spray jet nozzle (5). The protective gas nozzle (6) has a core hollow space (26) with a curved closing surface (9) at the rear end (8) of the nozzle (6). With this, the protective gas nozzle (6) with the gas feed channel (10) and the wall (13) lying opposite forms a nozzle channel (14) which at first extends radial and then about parallel between the gas feed channel (10) and the core hollow space (26).
