Abstract
Anode-cathode and nozzle-cathode voltages, plenum pressure and gas mass flow measurements in a
low current (30 A) cutting torch, operated with oxygen gas, are used as inputs for an electrical model coupled
to a simplified fluid model, in order to infer some properties of the plasma-gas structure that are difficult to
measure.
