Abstract (en)
[origin: EP1402977A1] Protective gas device comprises a melting furnace (1) with openings for introducing a protective gas, different gas sources, and a pressure storage container for receiving a mixture of the individual protective gas components. The openings of the melting furnace are provided with inlet nozzles (9, 9a) which are impinged by a dosing unit (7) having an operating pressure equal to or lower than the pressure in the container but high enough to effect beam widening behind the inlet nozzles.
