The effect of a ledge in outlet electrode on operation efficiency of the two-chamber plasmatorch

Investigation of the characteristics of an electric arc plasmatron with variable geometry electrodes

“…1. This circuit differs from the two-chamber circuit in that the output electrode is made with a change in the geometry of the output electrode [3]. In single-chamber plasmatrons, a stepped electrode is used to obtain the currentvoltage characteristic (CVC) of an arc with an increasing curve [2].…”
