WARNING
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
Plasma arc cutting produces intense electric and magnet-
ic emissions that may interfere with the proper function
of cardiac pacemakers, hearing aids, or other electronic
health equipment. Persons who work near plasma arc
cutting applications should consult their medical health
professional and the manufacturer of the health equip-
ment to determine whether a hazard exists.
To prevent possible injury, read, understand and follow
all warnings, safety precautions and instructions before
using the equipment. Call 1-603-298-5711 or your local
distributor if you have any questions.

Notes
1. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is re-
duced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
2. Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause
double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting perfor-
mance and rapid electrode wear. Optional filters provide increased filtering capabilities.
NOTE
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifica-
tions include calculating an output voltage based upon power supply rated current. To facilitate comparison
between power supplies, all manufacturers use this output voltage to determine duty cycle.
TDC Rating is determined using an output voltage representative of actual output voltage during cutting
with a TDC torch. This voltage may be more or less than IEC voltage, depending upon choice of torch,
consumables, and actual cutting operation.

INTRODUCTION 2T-2 Manual 0-5141
2T.03 Introduction to Plasma
A. Plasma Gas Flow
Plasma is a gas which has been heated to an extremely
high temperature and ionized so that it becomes electri-
cally conductive. The plasma arc cutting and gouging
processes use this plasma to transfer an electrical arc
to the workpiece. The metal to be cut or removed is
melted by the heat of the arc and then blown away.
While the goal of plasma arc cutting is separation of
the material, plasma arc gouging is used to remove
metals to a controlled depth and width.
In a Plasma Cutting Torch a cool gas enters Zone B,
where a arc between the electrode and the torch tip
heats and ionizes the gas. The main cutting arc then
transfers to the workpiece through the column of
plasma gas in Zone C.
By forcing the plasma gas and electric arc through a
small orifice, the torch delivers a high concentration
of heat to a small area. The stiff, constricted plasma
arc is shown in Zone C. Direct current (DC) straight
polarity is used for plasma cutting, as shown in the
illustration.
Zone A channels a secondary gas that cools the torch.
This gas also assists the high velocity plasma gas in
blowing the molten metal out of the cut allowing for a
fast, slag - free cut.

Typical Torch Head Detail
B. Gas Distribution
The single gas used is internally split into plasma and
secondary gases.
The plasma gas owsinto thetorchthrough the
negative lead, through the starter cartridge, around
the electrode, and out through the tip orifice.
Thesecondarygasowsdownaroundtheoutside
of the torch starter cartridge, and out between the tip
and shield cup around the plasma arc.
C. Pilot Arc
When the torch is started a pilot arc is established
between the electrode and cutting tip. This pilot
arc creates a path for the main arc to transfer to the
work.
D. Main Cutting Arc
DC power is also used for the main cutting arc. The
negative output is connected to the torch electrode
through the torch lead. The positive output is con-
nected to the workpiece via the work cable and to the
torch through a pilot wire.
E. Parts - In - Place (PIP)
The torch includes a 'Parts - In - Place' (PIP) circuit.
When the shield cup is properly installed, it closes
a switch. The torch will not operate if this switch is
open.
