    摘要: In an arrangement for use in burning and cutting torches and like devices where the torch utilizes an oxidizing medium supplied to the torch at a selected pressure and a fuel supplied to the torch at a selected pressure, where the fuel and oxidizing medium are independently supplied to the cutting torch and mixed therein, the present invention provides a fire extinguishing medium, supplied under pressure to the cutting torch vicinity, where the pressure of the extinguishing medium supply source is utilized to operate valve means to control the flow of oxidizer and fuel.

    摘要: A cutting-welding torch wherein all of the oxygen and fuel valves including the high pressure oxygen control for cutting are incorporated in the torch handle assembly. The high pressure cutting oxygen passage in the handle assembly is automatically blocked upon connection of a welding tip to the assembly to prevent inadvertent introduction of excess oxygen during welding usage of the torch. Upon coupling of a cutting tip to the handle assembly, the high pressure oxygen passage is opened to permit selective passage of high pressure oxygen for cutting purposes.
