Abstract: In a glue gun for conducting adhesive bonding by means of a heated adhesive, with a housing having a heating section and an angled handle, a hollow, thermally conductive block being arranged in the heating section for the accommodation of adhesive, the provision is made, to afford the possibility of using the glue gun independently of an external fuel supply, that a hollow combustion chamber provided with air inlet openings is fashioned integrally with the metal block; that a fuel tank is arranged in the handle; and that a connecting conduit is extended from the tank to the combustion chamber, a shutoff element being arranged in this connecting conduit, the combustion chamber in particular being disposed at least partially annularly around the block.
