ABSTRACT:
A multiple piece cutting tip for a cutting torch. An outer body with an inner body coaxially positioned therein forms a first passageway therebetween for transmitting preheat fuel and oxygen. A helical mixer in the first passageway more completely mixes the fuel and the oxygen. The first passageway includes a plurality of openings about the inner body at the tip end of the first passageway for preheating. The inner body includes a second passageway therethrough for the passage of cutting oxygen and the inner body includes a connection for changing the cross-sectional area of the second passageway. Radially extending ribs are provided about the outside of the outer body adjacent the tip for dissipating heat. The size of the second passageway may be modified by an elongate tubular member adapted to be threaded into the inner body and telescopically extend into the second passageway for changing the size of the second passageway.
