Patent ID: 8901461

Claim:
A wax melting system comprising: a melting stage and a holding stage, the melting stage comprising a porous bottom, the porous bottom configured to permit flow of melted wax from the melting stage to the holding stage; and a vessel comprising an electrical power distribution system coupled to the melting stage and the holding stage, wherein the melting stage and the holding stage are coupled to the vessel through a bracket coupled to the vessel, and the electric power distribution system comprises: a first set and a second set of electrical contacts comprised in the bracket, each set of electrical contacts comprising two contacts, the first set of electrical contacts oriented above the second set of electrical contacts; a first heating element and a second heating element, the first heating element coupled to the first set of electrical contacts and the second heating element coupled to the second set of electrical contacts, the first heating element comprised in the melting stage and the second heating element comprised in the holding stage, the first heating element substantially identical to the second heating element; and a transformer, wherein the first set of electrical contacts is maintained at a higher voltage than the second set of electrical contacts through the transformer; wherein the melting stage and the holding stage are coupled with the vessel, the melting stage is oriented above the holding stage, and the vessel encloses both the holding stage and the melting stage during a heating operation; and wherein the temperature of the melting stage is maintained above the temperature of the holding stage through the electric power distribution system.
