Abstract
A gas powered soldering tool (1) comprising a main body memb er (4) terminating in a soldering tip portion (8) has a combustion chamber (10) located therein. A gas catalytic combustion element (12) is locaed in the combustion chamber (10), and fuel gas is delivered into the combustion chamber (10) from a jet nozzle (15) and an air mixing venturi bore (17). A temperature responsive controller (28) for controlling the fuel gas supply to the jet nozzle (15 ) comprises a valve (39) having a valving member (58) which is operable by a permanent magnet (63) slidably located in a bore (64). A first member (70) of thermomagnetic material the Curie point of which is substantially similar to the temperature at which the main body member (4) is to be controlled is located at one end of the bore (64). The magnetic attraction between the first member (70) and the permanent magnet (63) is greater than the magnetic attraction between a second member (71) in the bore (64) and the permanent magnet (63) when the first member (70) is magnetic, thereby maintaining the valve (39) open, and vice versa when the first member (70) becomes non-magnetic for closing the valve (39).
