  • Interpretation of Voltage Measurements in Cutting Torches. 

    Prevosto, Leandro; Kelly, Héctor; Minotti, Fernando Oscar; Mancinelli, Beatriz; https://orcid.org/0000-0002-8771-9549; https://orcid.org/0000-0003-0577-9589 (2015)
    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 ...

  • Numerical Modelling of a Cutting Arc Torch 

    Mancinelli, Beatriz; Minotti, Fernando Oscar; Prevosto, Leandro; Kelly, Héctor (Jan Awrejcewicz. INTECH, 2014-02-14)
    Plasma cutting is a process of metal cutting at atmospheric pressure by an arc plasma jet, where a transferred arc is generated between a cathode and a work-piece (the metal to be cut) acting as the anode . Small nozzle ...

  • On the influence of the nozzle length on the arc properties in a cutting torch 

    Prevosto, Leandro; Kelly, Héctor; Risso, Marcelo Natalio; Infante, Damián Leandro (2009)
    In this work, an experimental study on the influence of the nozzle geometry on the physical properties of a cutting arc is reported. Ion current signals collected by an electrostatic probe sweeping across a 30 A oxygen ...
