!
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.
• The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings on the metal, and the different processes. You must be very careful when cutting or welding any metals which may contain one or more of the following:
Antimony Chromium Mercury
Arsenic Cobalt Nickel Barium Copper Selenium Beryllium Lead Silver Cadmium Manganese Vanadium
• Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are using. These MSDSs will give you the information regarding the kind and amount of fumes and gases that may be dangerous to your health.
• For information on how to test for fumes and gases in your workplace, refer to item 1 in Subsection 1.03, Publications in this manual.
• Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.
• Do not use the plasma torch in an area where combustible or 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.)
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.
SECTION 1:
GENERAL INFORMATION
CUTMASTER A80, A120
GENERAL INFORMATION 1-2 Manual 0-5119
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.
• 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. Trapped hydrogen gas that is ignited will cause an explosion.
NOISE
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.
• To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs. Protect others in the workplace.
• Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.
• For information on how to test for noise, see item 1 in Sub­section 1.03, Publications, in this manual.
PLASMA ARC RAYS
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.
• To protect your eyes, always wear a welding helmet or shield. Also always wear safety glasses with side shields, goggles or other protective eye wear.
• Wear welding gloves and suitable clothing to protect your skin from the arc rays and sparks.
• Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays. Use protec­tive booths, screens or shields.
• Use the shade of lens as suggested in the following per ANSI/ASC Z49.1:
Minimum Protective Suggested Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12

2T.01 Scope of Manual
This manual contains descriptions, operating instructions and maintenance procedures for the 1Torch Models SL100SV/Manual and SL100SV/ Mechanized Plasma Cutting Torches. Service of this equipment is restricted to properly 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 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 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 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.

Manual 0-5119 2T-3 INTRODUCTION
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.

Workpiece

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.

2. Connect the input power cable (or close
the main disconnect switch) to supply power to the system.
Air Source
Ensure source meets requirements (refer to Section
2). Check connections and turn air supply on.
Connect Work Cable
Clamp the work cable to the workpiece or cutting table. The area must be free from oil, paint and rust. Connect only to the main part of the work­piece; do not connect to the part to be cut off.
Art # A-04509
Power On
Place the Power Supply ON / OFF switch to the ON (up) position. AC indicator turns on.
Gas indicator turns on if there is sufficient gas pressure for power supply operation and the cool­ing fans turn on.
NOTE
Minimum pressure for power supply operation is lower than minimum for torch operation.
The cooling fans will turn on as soon as the unit is turned on. After the unit is idle for ten (10) minutes the fans will turn off. The fans will come back on as soon as the torch switch (Start Signal) is activated or if the unit is turned off, then turned on again. If an over temperature condition occurs, the fans will continue to run while the condition exists and for a ten (10) minute period once the condition is cleared.

Select Current Output Level
1. Place the Function Control Knob in one of the three operating positions available:
RUN ,
RAPID AUTO RESTART
or LATCH . Gas ow stops.
2. Set the output current to desired amper­age with the Output Current Control Knob.
Pre-flow
With hand or mechanical torch, there will be a .5 second pre-flow of the gas. Pre-flow does not apply to automation torch use.
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 LATCH position the main cutting arc will be maintained after the torch switch is released.
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.

4T.01 Machine and Automated
Torch Operation
Cutting With Machine or Automated Torch
These torches are 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.
Standoff Distance
Straight Arc
Trailing Arc
Leading Arc
Direction of Torch Travel
A-02586
Automation and 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.
Piercing With Machine or Automated Torch
To pierce, 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.

4T.04 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 cutting
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:

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.

OPERATION 4T-4 Manual 0-5119
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.05 General Cutting Information
!
WARNINGS
Disconnect primary power at the source before disassembling the power supply, torch, or torch leads.
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.
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.
Right Side
Cut Angle
Left Side
Cut Angle
A-00512
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.
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.

• Torch parts wear
• Air quality
• Line voltage uctuations
• Torch standoff height
• Proper work cable connection
4T.07 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.09, Torch Parts Selection.
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.
CUMASTER A80, A120
Manual 0-5119 4T-9 OPERATION
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.

A-00941_AB
Gouging Angle and Standoff Distance
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.

5T.01 General Maintenance
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.
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.
It is recommended to apply a very light film of o­ring lubricant (Catalog # 8-4025) to the o-rings on a weekly basis.

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.

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.
2. Inspect the cup for damage. Wipe it clean or replace if damaged.
Art # A-08067
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 O­ring.
4. Remove the tip. Check for excessive wear (in­dicated by an elongated or oversized orifice). Clean or replace the tip if necessary.
