Abstract
A soldering tool comprising a soldering tip and a handle in which is housed a fuel gas reservoir. Gas is delivered from the reservoir through the handle to a permeable gas catalytic combustion element to heat the soldering tip. The catalytic element extends around a support member. Heat is conducted from the support member into the soldering portion of the tip.
Claims12
In a gas powered soldering tool comprising:
- a handle;
- a soldering tip mounted to said handle,
- said soldering tip comprising;
- a solid soldering portion body of heat conductive material having a tubular catalytic housing extending rearwardly therefrom to form a combustion chamber;
- a gas catalytic combustion element provided within the combustion chamber;
- and
- fuel supply means in the handle for selectively delivering fuel gas to the catalytic combustion element;
- the improvement comprising;
- a heat conductive support member having a gas passage forming a gas inlet and a gas outlet, said support member extending through the combustion chamber with said gas outlet opening to said combustion chamber for delivering fuel gas to the catalytic combustion element, said support member having one end directly coupled to the tip solid soldering portion body for conducting heat from the support member to the solid soldering portion body of the soldering tip internally of the catalytic combustion element and for solely supporting the soldering tip, and said support member having the opposite end coupled to the handle and to the fuel supply means.
