Abstract

See full text

A system for the efficient utilization of plasma torch post arc cooling gas includes a controller configured to automatically determine a post arc gas flow duration. The controller monitors a plasma arc parameter associated with a temperature of the plasma torch at arc termination. The controller dynamically determines the duration of post arc gas flow through the torch from the plasma arc parameter.
