Abstract:
1. A lead set measurement system for a thermal processing system comprising: a lead set having a length extending from a first end of the lead set coupled to a thermal processing system power source to a second end connected to a plasma arc torch; a component, comprising a tube, disposed along the length of the lead set for transporting at least one gas through the tube, the component having a tube volume that is a function of the length of the lead set; and a sensing apparatus disposed in the thermal processing system power source and configured to receive a first signal and a second signal, wherein (i) one of the first or second signal corresponds to actuating a gas valve disposed relative to the lead set and (ii) the length of the lead set is determined based upon a time period between the first signal and the second signal that is dependent on the tube volume.
