摘要： In some aspects, methods of disengaging a plasma control circuit within a plasma arc torch of a plasma processing system to place the torch into a safety-locked mode can include providing: a plasma control circuit configured to convey a current from the plasma cutting system through the plasma arc torch to one or more consumables disposed in the torch and an operator interface switch connected to the plasma control circuit and configured to initiate generation of a plasma arc from the plasma arc torch; and activating a switch, separate from the operator interface switch, disposed on the torch and connected to the plasma control circuit to disconnect the plasma control circuit to limit the current, including pilot current, from flowing to the one or more consumables.

摘要： A lead connector is provided for connecting a plasma torch lead of a plasma arc torch to a power supply of a plasma cutting system. The lead connector includes a base portion, a central conduit disposed in the base portion, where the central conduit is configured to carry a gas and a torch current to the plasma arc torch, and multiple pins disposed radially about a center of the central conduit. The pins are located at a radius of between about 0.4 inches and about 0.65 inches from the center of the central conduit on a radial plane of the base portion. The pins include one or more pilot carrying pins and one or more control signal pins located from about 27 degrees to about 64 degrees and from about 120 degrees to about 170 degrees, respectively, about the center of the central conduit on the radial plane.
