ABSTRACT:
A soldering tool comprises a cylindrical gas tank 10 which stores fuel gas and also encloses the greatest part of a switching and pressure regulating device. This device is composed of a rear barrel assembly 20 which contains a gas intake rod 25, a needle valve 311, gas filters, sealing or stopping rings and a gas inlet hole 314 through the valve stem wall, sealing or stopping rings, and a front barrel assembly 40 which is connected to the rear barrel assembly with a connector 42 provided with a further filter and a nozzle 426. Air inlet hole 314 provided in the side wall of the front barrel lets air mix with the gas flow just passing through the nozzle. The mixed fuel stream passes through a cooling fin assembly 50 and reaches the tool head which may have a catalytic heated soldering tip or a hot knife, or a torch. Through successive filtering, stopping, expanding and mixing, the fuel-air mixture of clean and well controlled pressure provides a desired quality and quantity for use with water.
