Abstract
In some aspects, torch receptacles for coupling a plasma arc torch to a torch lead can include: a body having a first end to connect to the torch lead and a second end to connect to a torch body; a set of ports within the first end to fluidly connect to a set of fluid conduits within the torch lead; and a multiway valve within the body and fluidly connected to the set of ports and to a torch gas conduit formed in the second end, the multiway valve being configured to: i) manipulate a flow of fluids between the first end and the second end to select from primary gases entering the set of ports, ii) deliver a selected primary gas to the torch body through the torch gas conduit, and iii) fluidly connect the torch gas conduit to a gas supply manifold of the plasma cutting system.
