ABSTRACT:
A portable solder iron includes a hollow barrel having a free tapered end; first and second burners positioned in a free tapered end; a burner having separate, independently controlled gas supply paths positioned in the barrel, the supply paths including first and second tubes, each tube having a free end; a single junction tube joining together the free ends of the first and second tubes, the junction tube having a free end adajcent the tapered free end of the barrel for heating the same; a fuel supply cartridge which supplies fuel to the first and second tubes and which controls the flow of fuel from the cartridge; an ignitor assembly for igniting the fuel escaping from the free end of said junction tube; a plunger which applies a force to the valve in response to user actuation, to start fuel flow; a regulator including a diaphragm which maintains a substantially constant flow rate of fuel to the first and second tubes; a valve stem through which the fuel travels from the cartridge to the second tubes; a bimetallic element for applying a force to the valve stem to permit fuel flow to the second tube when the temperature is less than a predetermined start-up temperature and for removing such force otherwise; and a spring which applies a reverse force to the valve stem to prevent fuel flow to the second tubes when the predetermined start-up temperature is attained, so as to achieve fast heat up of the barrel.
