1.02 Important Safety Precautions
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 pacemak
ers, 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.

regarding the kind and amount of fumes and gases
that may be dangerous to your health.
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.)
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.
Plasma Arc Rays can injure your eyes and burn your skin.
The plasma arc process produces very bright ultra violet
and infra red light. These arc rays will damage your eyes
and burn your skin if you are not properly protected.
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. Trapped
hydrogen gas that is ignited will cause an explosion.
* These values apply where the actual arc is
clearly seen. Experience has shown that lighter
filters may be used when the arc is hidden by
the workpiece.
Noise can cause permanent hearing loss. Plasma arc
processes can cause noise levels to exceed safe limits.
You must protect your ears from loud noise to prevent
permanent loss of hearing.

INTRODUCTION
2.01 Scope of Manual
This manual contains descriptions, operating instructions
and maintenance procedures for the 1Torch Models SL60
and SL100 Plasma Cutting Torches. Service of this equipment is restricted to properly trained personnel; unqualified
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.
2.02 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
is divided inside the torch head. Single - gas operation
provides a smaller sized torch and inexpensive operation.

m cable which can be added to the Hand Pendant
Control cable to provide a total control cable length
of 50 ft / 15.2 m.
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.
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.

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. Capacitive Discharge
Because direct current (DC) alone is not sufficient to
strike and maintain the pilot arc, capacitive discharge
is also used. The high voltage jumps between the tip
and electrode with the DC following.
NOTE
Not all power supplies have this feature.
E. 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.
F. 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.

Refer to Appendix Pages for additional informa
tion as related to the Power Supply used.
Cut quality requirements differ depending on application.
For instance, nitride build - up and bevel angle may be
major factors when the surface will be welded after cutting.
Dross - free cutting is important when finish cut quality
is desired to avoid a secondary cleaning operation. The
following cut quality characteristics are illustrated in the
following figure:

whose orifice has become elongated.
4.06 General Cutting Information
WARNINGS
Disconnect primary power at the source before
disassembling the power supply, torch, or torch
leads.
Piloting is harder on parts life than actual cutting
because the pilot arc is directed from the electrode to
the tip rather than to a workpiece. Whenever possible,
avoid excessive pilot arc time to improve parts life.
B. Torch Standoff
Improper standoff (the distance between the torch tip
and workpiece) can adversely affect tip life as well as
shield cup life. Standoff may also significantly affect
the bevel angle. Reducing standoff will generally result
in a more square cut.
C. Edge Starting
For edge starts, hold the torch perpendicular to the
workpiece with the front of the tip near (not touching)
the edge of the workpiece at the point where the cut
is to start. When starting at the edge of the plate, do
the edge of the metal. Establish the cutting arc as
quickly as possible.
D. Direction of Cut
In the torches, the plasma gas stream swirls as it
leaves the torch to maintain a smooth column of gas.
This swirl effect results in one side of a cut being more
square than the other. Viewed along the direction of
travel, the right side of the cut is more square than
the left.
Frequently review the Important Safety Pre
cautions at the front of this manual. Be sure
the operator is equipped with proper gloves,
clothing, eye and ear protection. Make sure no
part of the operator’s body comes into contact
with the workpiece while the torch is activated.

tip as soon as possible. Spraying the shield cup in
anti - spatter compound will minimize the amount
of scale which adheres to it.
4.08 Machine Torch Operation
A. Cutting With Machine Torch
The machine torch can be activated by remote control
pendant or by a remote interface device such as CNC.
1. Use a square to check that the torch is perpendicular to the workpiece to obtain a clean, vertical cut.
3. Trailing Arc
The trailing arc is directed in the opposite direction
as torch travel.
2. To start a cut at the plate edge, position the center
of the torch along the edge of the plate.
B. Travel Speed
Proper travel speed is indicated by the trail of the arc
which is seen below the plate. The arc can be one of
the following:
1. Straight Arc
A straight arc is perpendicular to the workpiece
surface. This arc is generally recommended for the
best cut using air plasma on stainless or aluminum.
2. Leading Arc
The leading arc is directed in the same direction as
torch travel. A five degree leading arc is generally
recommended for air plasma on mild steel.
Checking Alignment
Machine Torch Operation
For optimum smooth surface quality, the travel speed
should be adjusted so that only the leading edge of
the arc column produces the cut. If the travel speed
is too slow, a rough cut will be produced as the arc
moves from side to side in search of metal for transfer.
Travel speed also affects the bevel angle of a cut. When
cutting in a circle or around a corner, slowing down
the travel speed will result in a squarer cut. The power
source output should be reduced also. Refer to the
appropriate Control Module Operating Manual for any
Corner Slowdown adjustments that may be required.
Manual 0-2962 4-7 OPERATION
Page 32
C. Piercing With Machine Torch
To pierce with a machine torch, the arc should be
started with the torch positioned as high as possible
above the plate while allowing the arc to transfer and
pierce. This standoff helps avoid having molten metal
blow back onto the front end of the torch.
Refer to Appendix Pages for cutting speed
chart information as related to the Power Supply used.
4.10 Gouging
When operating with a cutting machine, a pierce or
dwell time is required. Torch travel should not be
enabled until the arc penetrates the bottom of the
plate. As motion begins, torch standoff should be
reduced to the recommended 1/8 - 1/4 inch (3-6 mm)
distance for optimum speed and cut quality. Clean
spatter and scale from the shield cup and the tip as
soon as possible. Spraying or dipping the shield cup
in anti - spatter compound will minimize the amount
of scale which adheres to it.
4.09 Recommended Cutting Speeds
Cutting speed depends on material, thickness, and the
operator’s ability to accurately follow the desired cut line.
The following factors may have an impact on system
performance:
• Torchpartswear
• Airquality
• Linevoltageuctuations
• Torchstandoffheight
• Properworkcableconnection
NOTES
This information represents realistic expecta
tions using recommended practices and well
- maintained systems. Actual speeds may vary
up to 50% from those shown.
-
WARNINGS
Be sure the operator is equipped with proper
gloves, clothing, eye and ear protection and
that all safety precautions at the front of this
manual have been followed. Make sure no part
of the operator’s body comes in contact with the
workpiece when the torch is activated.
Disconnect primary power to the system be
fore disassembling the torch, leads, or power
supply.
CAUTIONS
Sparks from plasma gouging can cause damage to coated, painted or other surfaces such
as glass, plastic, and metal.
Check torch parts. The torch parts must cor
respond with the type of operation. Refer to
Section 4.04, Torch Parts Selection.
A. Gouging Parameters
Gouging performance depends on parameters such as
torch travel speed, current level, lead angle (the angle
between the torch and workpiece), and the distance
between the torch tip and workpiece (standoff).
B. Torch Travel Speed
NOTE
-
-
Refer to Appendix Pages for additional informa
-
tion as related to the Power Supply used.
Optimum torch travel speed is dependent on current
setting, lead angle, and mode of operation (hand or
machine torch).
OPERATION 4-8 Manual 0-2962
Page 33
C. Current Setting
35°
Workpiece
Torch Head
Standoff Height
A-00941_AB
Current settings depend on torch travel speed, mode
of operation (hand or machine torch), and the amount
of material to be removed.
D. Lead Angle
The angle between the torch and workpiece depends
on the output current setting and torch travel speed.
At 80 amps, the recommended lead angle is 35°. At
a lead angle greater than 45° the molten metal will
not be blown out of the gouge and may be blown back
onto the torch. If the lead angle is too small (less than
35°), less material may be removed, requiring more
passes. In some applications, such as removing welds
or working with light metal, this may be desirable.
E. Standoff Distance
The tip to work distance affects gouge quality and
depth. Standoff distance of 1/8 - 1/4 inch (3 - 6 mm)
allows for smooth, consistent metal removal. Smaller
standoff distances may result in a severance cut rather
than a gouge. Standoff distances greater than 1/4 inch
(6 mm) may result in minimal metal removal or loss
of transferred main arc.
F. Slag Buildup
Slag generated by gouging on materials such as carbon and stainless steels, nickels, and alloyed steels,
can be removed easily in most cases. Slag does not
obstruct the gouging process if it accumulates to the
side of the gouge path. However, slag build - up can
cause inconsistencies and irregular metal removal if
large amounts of material build up in front of the arc.
The build - up is most often a result of improper travel
speed, lead angle, or standoff height.

damage to coated, painted, and other surfaces
such as glass, plastic and metal.
-
A. Cleaning Torch
Even if precautions are taken to use only clean air with
a torch, eventually the inside of the torch becomes
coated with residue. This buildup can affect the pilot
arc initiation and the overall cut quality of the torch.
WARNINGS
Disconnect primary power to the system before
disassembling the torch or torch leads.
DO NOT touch any internal torch parts while the
AC indicator light of the Power Supply is ON.
The inside of the torch should be cleaned with electrical
contact cleaner using a cotton swab or soft wet rag. In
severe cases, the torch can be removed from the leads
and cleaned more thoroughly by pouring electrical
contact cleaner into the torch and blowing it through
with compressed air.
CAUTION
Dry the torch thoroughly before reinstalling.
NOTE
Handle torch leads with care and protect them
from damage.

B. O-Ring Lubrication
ATC Male Connector
Art #A-03791
Gas Fitting
O-Ring
5.03 Common Operating Faults
This section applies only to torches withATC connectors.
An o-ring on the Torch ATC Male Connector requires
lubrication on a regular basis, depending on how frequently the torch is disconnected and re-connected.
This will allow the o-ring to remain pliable and provide
a proper seal. The o-ring will dry out, becoming hard
and cracked, if the o-ring lubricant is not used on a
regular basis. This can lead to potential performance
problems.
It is recommended to apply a very light film of o-ring
lubricant (Catalog # 8-4025) to the o-ring on a weekly
basis.
snugly against the shield cup body. In shielded drag
cutting operations (only), there may be an O-ring
between the shield cup body and drag shield cap. Do
not lubricate the O-ring.
The shield cup holds the tip and starter car
tridge shield cup in place. Position the torch
with the shield cup facing upward to prevent
these parts from falling out when the cup is
removed.
1. Unscrew and remove the shield cup from the torch.
NOTE
Slag built up on the shield cup that cannot be
removed may effect the performance of the
system.
2. Inspect the cup for damage. Wipe it clean or replace
if damaged.
4. Remove the tip. Check for excessive wear (indicated
by an elongated or oversized orifice). Clean or replace
the tip if necessary.
Tip Wear
5. Remove the starter cartridge. Check for excessive wear,
plugged gas holes, or discoloration. Check the lower
end fitting for free motion. Replace if necessary.

6.06 Hand Torch Consumables
The illustration shows all consumable parts for the SL60
and SL100 hand torches. Refer to the Appendix pages
covering the power supply being used to ensure proper
selection for the application.
Various front - end torch parts are available for different
applications.
Use the single - piece shield cup for general purpose cutting operations with the torch tip in contact with the work
(up to 40 amps). This is the preferred method of cutting
sheetmetalupto3/16"or4.8mmthick.
Also use the single - piece Shield Cup for 'standoff' cut-
heat. This combination provides cutting results similar to
the single-piece Shield Cup, as well as easy change-over
to gouging or drag shield cutting.
Use the Shield Cup Body with the Drag Shield Cap for a
consistent standoff distance with the drag shield in contact
with the workpiece. This is a simple and operator-friendly
method of cutting between 50 and 100 amps.
Use the Shield Cup Body with the Gouging Shield Cap
for excellent gouging performance and enhanced torch
parts life.
The electrode and starter cartridge are the same for all
operations.

A. Hand Cutting Versus Machine (Mechanized) Cutting Speeds
Hand cutting speeds can be much less than those obtained from Machine (Mechanized) Type applications. Hand cutting application speeds mostly depend on operator experience. The cut quality obtained at slower speeds for a Hand
application is just as good as those obtained from a Machine application. As the cut speeds increase or decrease from
the Machine applications the following may occur:
