ABSTRACT:
A portable torch including: a gas tank containing therein a combustible gas and another gas tank containing therein a combustion supporting gas; a plurality of pressure regulating mechanisms, in which the primary pressure sides are connected to said gas tanks through plug opening mechanisms, respectively; and a torch portion is connected to the secondary pressure sides of the pressure regulating mechanisms through flexible gas feeding tubes, respectively, provided at the forward end thereof with a jet and having no gas flow rate regulating function. The pressure regulating mechanisms regulate the secondary pressure and gas flow rate from the jet through the secondary pressure. Check valves for blocking the flow of gas from the torch portion to the pressure regulating mechanisms is interposed between the respective pressure regulating mechanisms and the torch portion, to thereby prevent backfire of the flame of the jet.
