ABSTRACT:
A low wattage device for heat-liquefying material is described which employs a low volume mass electrical heat exchanger structure to generate a high power density within a dispensing tip; and simultaneously by actuation of an operator controlled momentary on/off switch for energizing the heat exchanger structure heater, the heat-liquefiable material is pressed into effective contact with the heat exchanger structure. The heat exchanger structure is formed by positioning a resistive heating element in contiguous relation to the outer wall of a low volume thermal conducting mass formed into a heat-liquefying material conductor and generates sufficiently high heat at a relatively low wattage to effectively achieve the desired melting within a few seconds. In a further feature, an insulating shield partially envelopes the heat exchanger structure to prevent contact with the resistive heating element and to minimize heat loss.
