The heater illustrated here consists of a variable rheostat and a heating element. The latter is a short piece of Nichrome wire which has been coiled and attached to the rheostat via wires that run through a ball-point pen barrel. This permits a fine temperature control for melting dental wax and for controlling where the heat is applied.
