Abstract
In some aspects, a consumable for plasma arc torch that generates a predetermined plenum pressure from a substantially constant preset gas supply pressure from a plasma arc torch power supply, where the substantially constant preset gas supply being used to support plasma generation for a selection of multiple consumable components that each generate a different plasma plenum pressure for carrying out different processes, can include a proximal portion shaped to connect to the plasma arc torch and define a plasma gas inlet region; a distal portion shaped to define a gas outlet; and a pressure-matching stage comprising a pressure wall defining at least one flow path between the gas inlet region and the gas outlet configured to establish sufficient fixed pressure drop of a flow of gas flowing through the pressure-matching stage to reduce a pressure of the flow of gas to the predetermined plenum pressure.
