2.0 INTRODUCTION
2.01 INTRODUCTION
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 work-
piece. The metal to be cut is melted by the heat of the
arc and then blown away.

2.03 Features
• COMPACT and LIGHT - Designed for easy trans-
portation.
• ENERGY EFFICIENCY - Advanced technology
reduces power consumption.
• HIGH SPEED GENUINE CUTTING - The con-
stricted plasma arc provides high speed cutting
as well as a good quality genuine, narrow cut.
• LOW COST WITH COMPRESSED AIR - The unit
includes a compressor for its cutting and cooling
air.
• ALL KINDS OF METALS - Useful for most met-
als such as stainless steel, aluminum, mild steel,
copper and their alloys.
• PILOT ARC IGNITION FROM TORCH - The Pi-
lot Arc ignites the cutting arc.
• POWERFUL CUTTING PERFORMANCE -
Genuine cutting capacity is 3/16” (5mm) for
single phase and 1/4” (6mm) for three phase.
Maximum cutting capacity is 5/16” (8mm) for
single phase and 3/8” (10mm) for three phase.
• ABILITY TO CUT PAINTED MATERIALS - Pilot
Arc ignition allows the 20C to cut painted mate-
rials.
• EXTENDED PARTS LIFE - Consumable parts life
is longer.
