Abstract
A system for providing a dynamically controlled plasma cutting system. The plasma cutting system includes a proportional valve and a sensing device arrangement and a controller connected to this arrangement. The system is configured to dynamically control gas flow in a plasma torch. The system measures gas pressure at a proportional valve and makes necessary gas pressure adjustments in the system by way of controlling a drive signal sent to the proportional valve to control gas flow.
