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 tankhas a tank bodywhich houses molten solder S, a discharge pumpwhich pumps molten solder S, a discharge nozzlewhich spouts molten solder S which was sent to it by the discharge pumpupwards, a ducthaving the discharge pumpinstalled at one of its ends and the discharge nozzleinstalled at its other end, an oxidation preventing memberwhich has a prescribed size and which floats on the surface of the molten solder S, and an engaging meanswhich controls rotation of the oxidation preventing memberin a horizontal plane. The oxidation preventing memberhas a surrounding memberwhich extends downwards at its center and which surrounds the rotating shaftwith a gap between it and the rotating shaft, and a hollow spacein its interior for providing buoyancy.
