Claim Text:
1. A plasma arc torch comprising: a torch head having a proximal end portion and a distal end portion; a pre-flow gas conduit for directing a pre-flow gas through the plasma arc torch and extending into the proximal end portion of the torch head, the pre-flow gas conduit having a distal end portion; at least one plasma gas conduit for directing a plasma gas through the plasma arc torch and extending into the proximal end portion of the torch head, the plasma gas conduit having a distal end portion; and a gas control device disposed proximate the proximal end portion of the torch head and extending between the distal end portion of the pre-flow gas conduit and the distal end portion of the plasma gas conduit, the gas control device being operatively connected to each of the pre-flow gas conduit and the plasma gas conduit, and the gas control device disposed within a cavity arranged perpendicular to the pre-flow gas conduit and the at least one plasma gas conduit, wherein the gas control device slides perpendicularly within the cavity between the pre-flow gas conduit and the at least one plasma conduit to selectively allow one of the pilot gas and the plasma gas to flow through the plasma arc torch.
