摘要： A plasma arc torch is provided that includes a torch head, a pre-flow gas conduit for directing a pre-flow gas through the plasma arc torch, at least one plasma gas conduit for directing a plasma gas through the plasma arc torch, and a gas control device. The pre-flow gas conduit and the plasma gas conduit extend into a proximal end portion of the torch head. The gas control device is disposed proximate the torch head and extends between a distal end portion of the pre-flow gas conduit and a distal end portion of the plasma gas conduit. The gas control device is operatively connected to each of the pre-flow gas conduit and the plasma gas conduit. The gas control device selectively allows one of the pilot gas and the plasma gas to flow through the plasma arc torch.

摘要： An electrode for a plasma arc torch includes a conductive body and a plurality of emissive inserts. The conductive body includes a proximal end portion, a distal end portion and a cavity extending from the proximal end portion to the distal end portion. The distal end portion defines a distal end face. The plurality of emissive inserts extend through the distal end face. The conductive body further defines a dimple extending into the distal end face and at least partially into the emissive inserts. The dimple is positioned concentrically about a centerline of the conductive body.

摘要： A shield device for a plasma arc torch includes an inner shield member defining an inner auxiliary gas chamber and an outer shield member surrounding the inner shield member. An outer auxiliary gas chamber is defined between the inner shield member and outer shield member. The shield device allows an auxiliary gas flow to be split into a first flow of auxiliary gas through the inner auxiliary gas chamber and a second flow of auxiliary gas through the outer auxiliary gas chamber. The inner shield member and the outer shield member are configured to be mounted to the plasma arc torch as an integral unit.
