INTRODUCTION
2.01 Overview
Plasma is a gas which has been heated to an extremely
high temperature and ionized so that it becomes elec-
trically conductive. The plasma arc cutting process uses
this plasma to transfer an electrical arc to the workpiece.
The metal to be cut is melted by the heat of the arc and
then blown away.
