1 Introduction
Plasma Arc Cutting
A Plasma is a gas which has been ionized
by increasing the energy level to the point
were the electrons are stripped from the gas
molecule and are free to move. The free
moving electrons mean the gas can conduct
electricity, and the gas can reach high
temperatures of 20,000C.
A plasma is created by an arc. By allowing
more current to flow though the plasma, the
plasma energy can be increased. By forcing
a gas such as nitrogen, oxygen, argon, or
air through the plasma arc, a high energy
plasma stream is created.
These features of the plasma are exploited
when using the plasma cutter.
The Cutmatic 45 uses compressed air from
external source, as the gas medium for the
plasma.
The Plasma cutter torch, provides a pilot
arc to initiate the plasma stream. When the
Plasma stream is brought into contact with
the electrically conducive work piece, the
plasma current is transferred to the work
piece. The plasma power source increases
the current through the plasma. The high
temperature then melts the work piece and
the high volume of gas transports molten
material away from the cut.
The plasma process provides a low cost
method of cutting any conductive metal
including steel, alloyed steel, stainless steel,
cast iron, aluminium, aluminium alloys,
copper and copper alloys.
The Cutmatic 45 can clean cut ferrous
metal up to 16mm. Different nozzle sizes
are available, 1.0mm for high current and
0.8mm for low current applications.
