A gas-mixing and burning tool that produces a hot flame for the welding or cutting of metal. The torch usually delivers acetylene and commercially pure oxygen producing a flame temperature of 5000–6000°F (2750–3300°C), sufficient to melt the metal locally. The torch thoroughly mixes the two gases and permits adjustment and regulation of the flame. Acetylene requires 2.5 times its volume of oxygen for complete combustion and, being an endothermic compound of carbon and hydrogen, can produce a higher flame temperature than other fuel gases.
