Equipment-1
A hand torch can be used for simpler jobs, although industrial production generally uses
numerically controlled cutting tables, with one or more cutting heads, approximately as
for gas cutting. Noise, visual glare and smoke can be quite intensive, but
can be considerably reduced if the metal to be cut and the plasma nozzle are under water.
The arc electrode is normally tungsten or tungsten with thorium oxide. However, the
development of electrodes containing hafnium or zirconium has made it possible also to
use oxidising cutting gases, even to the extent of using ordinary air.
