ABSTRACT:
A lead oxide preventing apparatus for an automatic soldering device does not generate lead oxides around an impeller shaft inside a lead chamber. Industrial waste in the form of heavy-metal-contaminated material is reduced by installing a ring member and by placing an oxidation preventing agent into the ring members, or by installing a beating therein so that the molten lead does not contact portions of the impeller shaft.
