Abstract
A consumable for a plasma arc torch, such as a nozzle, having a body and a head defining a shoulder portion having a frusto-conical portion and a flared portion. The flared portion increases the cross-sectional thickness to provide a greater heat-conduction path for removal of heat generated by a plasma arc, thereby extending consumable life. The frusto-conical portion provides a sharper, pointier nozzle head to simultaneously increase the operator's visibility of the workpiece. Methods of making and using the consumables are also included.
