摘要：
The invention relates to a supply device (20) for feeding a gas to a wave brazing or tinning machine, wherein said machine is capable of generating at least one soldering wave, comprising: a gas inlet channel (22), a set of N secondary channels (24) immersed in the solder bath (9) of the brazing or tinning machine, and an injection channel (26) supplying at least one injection means (14, 19) for injecting the gas in the vicinity of said at least one wave (8A, 8B), each secondary channel (24) having its inlet end connected to the injection channel (26), characterised in that the number N of secondary channels (24) is equal to or higher than 1, and in that the inner diameter d of the secondary channels (24) and the gas flow rate Q0 in the inlet channel (22) are selected so that the gas flow in the secondary channels (24) is in a turbulent mode.
