2T.01 Scope of Manual
This manual contains descriptions, operating
instructions and maintenance procedures for the
1Torch Models SL60/Manual and SL100/Mechanized Plasma Cutting Torches. Service of this
equipment is restricted to properly trained person-
nel; 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
2T.03 Specifications
A. Torch Configurations
1. Hand/Manual Torch, Models
The hand torch head is at 75° to the torch handle.
The hand torches include a torch handle and torch
trigger assembly.
2. Mechanized Torch, Model
The standard machine torch has a positioning
tube with rack & pinch block assembly.
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 second-
ary 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.
B. Torch Leads Lengths
Hand Torches are available as follows:

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.

WARNING
This torch is not to be used with oxygen (O2).
NOTE
Operating pressure varies with torch model, operating amperage, and torch leads length. Refer to
gas pressure settings charts for each model.
H. Direct Contact Hazard
For standoff tip the recommended standoff is 3/16
inches / 4.7 mm.
2T.04 Options And Accessories
For options and accessories, see section 6.
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.

B. Gas Distribution
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.

Typical Cutting Speeds
Cutting speeds vary according to torch output amperage, the type of material being cut, and operator skill. Refer to Section 4T.08 and following for
greater details.
Output current setting or cutting speeds may be
reduced to allow slower cutting when following a
line, or using a template or cutting guide while still
producing cuts of excellent quality.
Postflow
Release the trigger to stop the cutting arc. Gas continues to flow for approximately 20 seconds. During
post - flow, if the user moves the trigger release to
the rear and presses the trigger, the pilot arc starts.
The main arc transfers to the workpiece if the torch
tip is within transfer distance to the workpiece.
Shutdown
Turn the ON / OFF switch to OFF
(down). All Power Supply indicators shut off.
Unplug the input power cord or disconnect input
power. Power is removed from the system.
Select Current Output Level
1. Place the Function Control Knob in one of
the three operating positions available:
RUN ,

or LATCH . Gas ow stops.
2. Set the output current to desired amperage
with the Output Current Control Knob.
Cutting Operation
When the torch leaves the workpiece during cutting
operations with the Function Control Knob in the
RUN position, there is a brief delay in restarting
the pilot arc. With the knob in the RAPID AUTO
RESTART position, when the torch leaves the workpiece the pilot arc restarts instantly, and the cutting
arc restarts instantly when the pilot arc contacts the
workpiece. (Use the 'Rapid Auto Restart' position
when cutting expanded metal or gratings, or in
gouging or trimming operations when an uninterrupted restart is desired). And with the knob in the

4T.02 Cut Quality
NOTES
Cut quality depends heavily on setup and
parameters such as torch standoff, alignment with
the workpiece, cutting speed, gas pressures, and
operator ability.
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 cut-
ting is important when nish cut quality is desired
to avoid a secondary cleaning operation. The
following cut quality characteristics are illustrated
in the following gure:
Bottom Dross Buildup
Molten material which is not blown out of the cut
area and resolidifies on the plate. Excessive dross
may require secondary cleanup operations after
cutting.
Kerf Width
The width of the cut (or the width of material removed during the cut).
Top Spatter (Dross)
Top spatter or dross on the top of the cut caused by
slow travel speed, excess cutting height, or cutting
tip whose orifice has become elongated.
4T.03 General Cutting Information
WARNINGS
Disconnect primary power at the source before
disassembling the power supply, torch, or torch
leads.
Cut Quality Characteristics
Cut Surface
The desired or specified condition (smooth or rough)
of the face of the cut.
Nitride Build - Up
Nitride deposits can be left on the surface of the cut
when nitrogen is present in the plasma gas stream.
These buildups may create difficulties if the material
is to be welded after the cutting process.
Bevel Angle
The angle between the surface of the cut edge and
a plane perpendicular to the surface of the plate.
A perfectly perpendicular cut would result in a 0°
bevel angle.
Top - Edge Rounding
Rounding on the top edge of a cut due to wearing
from the initial contact of the plasma arc on the
workpiece.
Frequently review the Important Safety Precautions 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.
CAUTION
Sparks from the cutting process can cause damage
to coated, painted, and other surfaces such as glass,
plastic and metal.
NOTE
Handle torch leads with care and protect them
from damage.
Piloting
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.

A-00512
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.
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 not pause at the edge and force the arc to
"reach" for the edge of the metal. Establish the cutting arc as quickly as possible.
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.
Dross
When dross is present on carbon steel, it is commonly referred to as either “high speed, slow speed,
or top dross”. Dross present on top of the plate is
normally caused by too great a torch to plate distance. "Top dross" is normally very easy to remove
and can often be wiped off with a welding glove.
"Slow speed dross" is normally present on the bottom edge of the plate. It can vary from a light to
heavy bead, but does not adhere tightly to the cut
edge, and can be easily scraped off. "High speed
dross" usually forms a narrow bead along the bottom
of the cut edge and is very difficult to remove. When
cutting a troublesome steel, it is sometimes useful
to reduce the cutting speed to produce "slow speed
dross". Any resultant cleanup can be accomplished
by scraping, not grinding.
4T.04 Hand Torch Operation
Standoff Cutting With Hand Torch
NOTE
For best performance and parts life, always use the
correct parts for the type of operation.
Side Characteristics Of Cut
To make a square - edged cut along an inside
diameter of a circle, the torch should move counterclockwise around the circle. To keep the square
edge along an outside diameter cut, the torch should
travel in a clockwise direction.
1. The torch can be comfortably held in one
hand or steadied with two hands. Position
the hand to press the Trigger on the torch
handle. With the hand torch, the hand may
be positioned close to the torch head for
maximum control or near the back end for
maximum heat protection. Choose the
holding technique that feels most comfortable and allows good control and movement.
NOTE
The tip should never come in contact with
the workpiece except during drag cutting
operations.

of normal operation. Do not attempt to force the
shield cup to close this gap. Forcing the shield
cup against the torch head or torch handle can
damage components.
8. For a consistent standoff height from the
workpiece, install the standoff guide by
sliding it onto the torch shield cup. Install
the guide with the legs at the sides of the
shield cup body to maintain good visibility
of the cutting arc. During operation, position the legs of the standoff guide against
the workpiece.

an impact on system performance:
• Torch parts wear
• Air quality
• Line voltage uctuations
• Torch standoff height
• Proper work cable connection

4T.05 Gouging
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 before disassembling the torch, leads, or power
supply.
CAUTION
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
correspond with the type of operation. Refer to
Section 4T.07, Torch Parts Selection.
Lead Angle
The angle between the torch and workpiece depends
on the output current setting and torch travel speed.
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.
Gouging Angle and Standoff Distance
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).
CAUTION
Touching the torch tip or shield cup to the work surface
will cause excessive parts wear.
Torch Travel Speed
NOTE
Refer to Appendix Pages for additional information
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).
Current Setting
Current settings depend on torch travel speed,
mode of operation (hand or machine torch), and the
amount of material to be removed.
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.
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.

4T.06 Mechanized Torch Operation
Cutting With Mechanized Torch
The mechanized torch can be activated by remote
control pendant or by a remote interface device
such as CNC.
1. To start a cut at the plate edge, position the
center of the torch along the edge of the
plate.
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.
3. Trailing Arc
The trailing arc is directed in the opposite direction as torch travel.
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.
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.
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.

Daily Operational Checks or Every Six Cutting
Hours:
1. Check torch consumable parts, replace if damaged
or worn.
2. Check plasma and secondary supply and pressure/flow.
3. Purge plasma gas line to remove any moisture
build-up.
Weekly or Every 30 Cutting Hours:
1. Check fan for proper operation and adequate air
flow.
2. Inspect torch for any cracks or exposed wires,
replace if necessary.
3. Inspect input power cable for damage or exposed
wires, replace if necessary.
Six Months or Every 720 Cutting Hours:
1. Check the in-line air filter(s), clean or replace as
required
2. Check cables and hoses for leaks or cracks, replace
if necessary.
3. Check all contactor points for severe arcing or
pits, replace if necessary.
4. Vacuum dust and dirt out of the entire machine.

NOTE
Refer to Previous "Section 5 System" for common
and fault indicator descriptions.
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.
It is recommended to apply a very light film of oring lubricant (Catalog # 8-4025) to the o-rings on a
weekly basis.
Torch Head O-Ring
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.
O-Ring Lubrication
An o-ring on the Torch Head and ATC Male Connector requires lubrication on a scheduled basis. This
will allow the o-rings to remain pliable and provide
a proper seal. The o-rings will dry out, becoming
hard and cracked if the lubricant is not used on a
regular basis. This can lead to potential performance
problems.
ATC O-Ring
NOTE
DO NOT use other lubricants or grease, they may
not be designed to operate within high temperatures or may contain “unknown elements” that
may react with the atmosphere. This reaction
can leave contaminants inside the torch. Either
of these conditions can lead to inconsistent performance or poor parts life.

5T.02 Inspection and Replacement
of Consumable Torch Parts
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.
Remove the consumable torch parts as follows:
NOTE
The shield cup holds the tip and starter cartridge
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.
4. Remove the tip. Check for excessive wear (indicated by an elongated or oversized orifice). Clean
or replace the tip if necessary.
Example of 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.
2. Inspect the cup for damage. Wipe it clean or
replace if damaged.
Shield Cups
3. On torches with a shield cup body and a shield
cap or deflector, ensure that the cap or deflector is
threaded 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.
6. Pull the Electrode straight out of the Torch Head.
Check the face of the electrode for excessive wear.
Refer to the following figure.
Electrode Wear
7. Reinstall the Electrode by pushing it straight into
the torch head until it clicks.
8. Reinstall the desired starter cartridge and tip into
the torch head.
9. Hand tighten the shield cup until it is seated on
the torch head. If resistance is felt when installing
the cup, check the threads before proceeding.
This completes the parts replacement procedures.
