Abstract: A torch handle is provided which includes a mechanism for locking the valve in the closed position. An actuator collar is positioned to be manually actuable with one hand to a forwardmost or open position. The quick-disconnect coupling assembly has a coupling collar, which may be retracted to remove a torch tip and thereby moves the actuator collar to return the valve to the closed position.

Abstract: A torch tip for burning an oxidizer/fuel combustible mixture includes a head having multiple burners so as to produce a plurality of flames. The torch tip includes a venturi acting as a jet pump using fuel metered through an orifice to draw an oxidizer in the form of air entering from cross passages into the venturi and then into a mixing chamber in the torch tip. The combustible mixture then exits into the burners through flameholders which impart a swirling motion to the combustible mixture so that more complete combustion and a higher temperature is achieved. Each flameholder also includes a bluff body portion thereon for causing eddying of the combustible mixture in the burners, thereby further enhancing flameholding and completeness of combustion.
