Abstract
A wave soldering tank is provided on which it is easy to perform maintenance, which does not have fluctuation of the height of spouted solder, which does not damage the rotating shaft of a discharge pump, and which can be stably used for long periods.The wave soldering tank 1 has a tank body 1a which houses molten solder S, a discharge pump 5 which pumps molten solder S, a discharge nozzle 4 which spouts molten solder S which was sent to it by the discharge pump 5 upwards, a duct 2 having the discharge pump 5 installed at one of its ends and the discharge nozzle 4 installed at its other end, an oxidation preventing member 22 which has a prescribed size and which floats on the surface of the molten solder S, and an engaging means 13 which controls rotation of the oxidation preventing member 22 in a horizontal plane. The oxidation preventing member 22 has a surrounding member 28 which extends downwards at its center and which surrounds the rotating shaft 10 with a gap between it and the rotating shaft 10, and a hollow space 26 in its interior for providing buoyancy.
