    Abstract: The main purpose of the invention is to limit corrosion in a vapour phase refusion machine. Chlorinated and fluoridised liquid is used in vapour phase welding machines. When decomposed by heat, ions are freed which, in the presence of water, form hydrofluoric and hydrochloric acids. They corrode both the tank (1) which makes the welding process possible and the metal parts of the welded components. The device of this invention eliminates the water from the secondary liquid (20) by isolating its vapours from the atmosphere, preventing water (21) from entering the drying cartridge (19) and facilitating drying before the use of the fresh secondary liquid (20). The invention applies mainly to vapour phase refusion welding.
