INTRODUCTION
2T.01Scope of Manual
This manual contains descriptions, operating instructions
and maintenance procedures for the 1Torch Models
SL100/Manual and SL100/Mechanized Plasma Cutting
Torches. Service of this equipment is restricted to prop-
erly trained personnel; unqualied personnel are strictly
cautioned against attempting repairs or adjustments not
covered in this manual, at the risk of voiding the Warranty.
Read this manual thoroughly. A complete understanding
of the characteristics and capabilities of this equipment
will assure the dependable operation for which it was
designed.
2T.02 General Description
Plasma torches are similar in design to the automotive
spark plug. They consist of negative and positive sec-
tions separated by a center insulator. Inside the torch,
the pilot arc starts in the gap between the negatively
charged electrode and the positively charged tip. Once
the pilot arc has ionized the plasma gas, the superheated
column of gas ows through the small orice in the torch
tip, which is focused on the metal to be cut.
A single torch lead provides gas from a single source to
be used as both the plasma and secondary gas. The
air ow is divided inside the torch head. Single - gas
operation provides a smaller sized torch and inexpensive
operation.
NOTE!
Refer to Section "2T.05 Introduction to
Plasma", for a more detailed description
of plasma torch operation.

2T.05Introduction 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 electrically 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 pilot 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.

Typical Torch Head Detail
By forcing the plasma gas and electric arc through a
small orice, 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 allow-
ing for a fast, slag - free cut.

ESAB CUTMASTER 100
300X5397 INTRODUCTION 2T-3
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 orice.
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.
