Abstract A cutting torch of divergent nozzle type having a primary cutting oxygan passage, a plurality of secondary cutting oxygen passages arranged in a ring-like form surrounding said primary cutting oxygen passage at the cutting tip, and at least one preheating flame passage arranged to surround said secondary cutting oxygen passages, said primary cutting oxygen passage having an intermediate reduced diameter portion terminating in a flared portion open at a circular nozzle outlet, and the jet of the secondary cutting oxygen from said secondary cutting oxygen passages being adapted to provide an apparent cutting oxygen outlet with a diameter equal to the inner diameter of the ring defined by said secondary cutting oxygen passages.
