The flame produced by the combustion of a mixture of oxygen and acetylene in various proportions. The proportions of these two gases affect the temperature of the flame; temperature is controlled by varying the ratio of oxygen to acetylene. See Table 0-1, Oxyacetylene Flame Temperatures. See also CARBURIZING FLAME, NEUTRAL FLAME, OXIDIZING FLAME and REDUCING FLAME.
Historical Background
Le Chatelier is credited with discovering the oxygen-acetylene flame in 1895. This flame produces the highest flame temperature 3482°C (6300°F) known to mankind. It is the flame most commonly used in welding and cutting operations. The first oxyacetylene torches were made by Fouche and Picard in 1900. See OXYACETYLENE WELDING.
