mANY THERMAL plasma torches have been developed for industrial applications. In order for them to be used
in various industries, the industries require high power, contaminant free, low cost, low maintenance, and large volume [1].
Conventional plasma torches are direct or alternating current
arc torches, induction torches, radio-frequency (RF) plasma
torches, etc. In general, arc torches are device of arc plasma
column generated between two electrodes.
