Abstract
A heating assembly for a fused bath is disclosed. The assembly includes a heating element within a tube. Also, disposed within the tube is a first thermocouple. A second thermocouple is positioned in the bath outside the tube. Control means are connected to the heating elements and thermocouples so that the heating of the bath is performed responsive to the temperature sensed by the second thermocouple; but, if the first thermocouple detects heat in the tube greater than a given value it will interrupt the heating operation to prevent damage to the heating elements due to over-heating.
