Abstract

A dip soldering process includes a reservoir of molten solder and a solder ladle for immersion therein to refresh the supply of ladled solder. The ladled solder is displaced by a displacement plunger to thereby overflow the ladle and carry with it surface contamination. Continued immersion of the plunger during the soldering operation of the workpiece accomplishes continual flow across the soldered workpiece thereby removing any contaminants which rise to the surface or are introduced by the workpiece.
