Abstract:
A drag tip for use in a plasma cutting torch is provided that includes an inner tip portion defining a distal end face, an inner cavity through which a plasma gas flows, and an orifice disposed between the distal end face and the inner cavity. An outer tip portion surrounds the inner tip portion and defines an inner chamber to accommodate a flow of secondary gas and also a distal end portion. The distal end face of the inner tip portion is adapted for contact with a workpiece and extends distally beyond the distal end portion of the outer tip portion, and the flow of secondary gas exits the outer tip portion proximate the distal end portion. Variations of the drag tip and methods of operation are also provided.
