explosive gases or materials are located.
• Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove all sources of these
vapors.
• This product, when used for welding or cutting, produces
fumes or gases which contain chemicals known to the State
of California to cause birth defects and, in some cases, cancer.
(California Health & Safety Code Sec. 25249.5 et seq.)
WARNINGS
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
Plasma arc cutting produces intense electric and
magnetic 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 equipment 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.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be
dangerous and hazardous to your health.
• Keep all fumes and gases from the breathing area. Keep your
head out of the welding fume plume.
• Use an air-supplied respirator if ventilation is not adequate to
remove all fumes and gases.
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses and
produces high voltage electrical energy. This electric energy can cause
severe or fatal shock to the operator or others in the workplace.
• Never touch any parts that are electrically “live” or “hot.”
• Wear dry gloves and clothing. Insulate yourself from the work
piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or
damp.
• Install and maintain equipment according to NEC code, refer
to item 9 in Subsection 1.03, Publications.
• Disconnect power source before performing any service or
repairs.
• Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma
arc.
• Be sure there is no combustible or flammable material in the
workplace. Any material that cannot be removed must be
protected.
• Ventilate all flammable or explosive vapors from the workplace.
Manual 0-4975 1-1 GENERAL INFORMATION
cutmaster 39
• Do not cut or weld on containers that may have held combustibles.
• Provide a fire watch when working in an area where fire hazards
may exist.
• Hydrogen gas may be formed and trapped under aluminum
workpieces when they are cut underwater or while using a water
table. DO NOT cut aluminum alloys underwater or on a water
table unless the hydrogen gas can be eliminated or dissipated.

Notes
1. Power supply accepts 120-230 VAC input power. No manual switching is required.
2. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is
reduced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
3. 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
performance and rapid electrode wear. Optional lters provide increased ltering capabilities.
NOTE
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifications
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.01 Scope of Manual
This manual contains descriptions, operating
instructions and maintenance procedures for
the 1Torch Model SL60 Plasma Cutting Torch.
Service of this equipment is restricted to properly trained personnel; unqualied 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 sections 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 orice 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.
Refer to the Appendix Pages for additional specifications as related to the Power Supply used.

2T.05 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 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.
2T.04 Options And Accessories
These items can adapt a standard system to a
particular application or further enhance performance.
• Deluxe Cutting Guide Kit - Easy add - on
attachments for precise straight line, circle
cutting, and beveling. Includes carrying
case.
• Trigger Guard Kits - These offer additional
protection from accidental activation of the
torch switch.
• Leads Extensions for torches with ATC con-
nectors
• Leather Leads Covers
Typical Torch Head Detail
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.

To Control
Cable Wiring
Torch Switch
The single gas used is internally split into plasma
and secondary gases.
The plasma gas flows into the torch through the
negative lead, through the starter cartridge, around
the electrode, and out through the tip orifice.
The secondary gas flows 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 connected 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.
