Abstract: A gas powered heating tool comprises a handle and a head which comprises a soldering tool element. Gas from a reservoir in the handle is delivered through a gas supply pipe to a combustion chamber where it is converted to heat by a catalytic heating element for heating the tool element. A nozzle orifice in a nozzle delivers a jet of gas through the gas supply pipe. The gas supply pipe conducts heat from the combustion chamber to a heat transfer member which in turn conducts heat to the nozzle to prevent freezing of gas in the nozzle orifice. Heat is also conducted to gas supply control means in the handle to prevent gas freezing.
