ABSTRACT:
The invention provides a portable soldering tool which eliminates the drawbacks such as unsteady heating and high fuel consumption of the conventional tools known heretofore. Essentially the soldering tool comprises a housing serving as a handle, wherein a gas tank, a gas duct with flow regulating means are housed. A tip assembly having a catalytic combustion element wrapped as the heating medium is connected to the front end of the housing, to be heated by the gas after it is mixed with air. An air-gas mixing chamber is provided at the end of the duct where the tip assembly is connected, the chamber being dome shaped and the flow regulator having dual assemblies including a needle valve and a nozzle both implemented with devices to retard the flow.
