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.
Claims4
A gas powered soldering tool comprising a housing serving as a handle, said housing having a front end (20) and a rear end (10), a tip assembly (30) connected to the front end of said housing, said tip assembly having a front end and a rear end, a heating element (52) inserted in the front end of said tip assembly, a dome-shaped air-gas mixing chamber (24) located in said front end of said housing, a gas tank (40) located in the rear end of said housing, said gas tank having a duct (57) at the front end thereof, said duct retaining a dual flow controlling assembly, said dual flow controlling assembly including a needle valve (50) and a nozzle assembly (60), the gas flowing from said gas tank through said needle assembly and said nozzle assembly to said air-gas mixing chamber, an air inlet (22) in the rear of said front housing for supplying air to the mixing chamber, a catalytic combustion element (313)being wrapped around said heating element.
