SAFETY PRECAUTIONS

WARNING

SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly installed, used, and maintained. Misuse of this equipment and other unsafe practices can be hazardous. The operator, supervisor, and helper must read and understand the following safety warnings and instructions before installing or using any welding or cutting equipment, and be aware of the dangers of the welding or cutting process. Training and proper supervision are important for a safe work place. Keep these instructions for future use. Additional recommended safety and operating information is referenced in each section.

WARNING

• This product contains chemicals, including lead, or otherwise produces chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. Wash hands after handling.

ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH

The purchaser is responsible for the safe installation, operation, and use of all products purchased, including compliance with all applicable ISO standards and local codes in the country of use. Do not service or repair equipment with power on. Do not operate equipment with protective insulators or covers removed. Service or repair to equipment must be done by qualified and/or trained personnel only.

Do not contact electrically live parts. Always wear dry welding gloves that are in good condition. Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders, chains, wires, ropes, cranes, and hoists away from any part of the electrical path. All ground connections must be checked periodically to determine if they are mechanically strong, and electrically adequate for the required current. When engaged in AC welding/cutting under wet conditions or where perspiration is a factor, the use of automatic controls for reducing the no load voltage is recommended to reduce shock hazards. Accidental contact must be prevented when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation or other means. When welding is to be suspended for any length of time, such as during lunch or overnight, all electrode holders and electrodes should be removed from the electrode holder and the power supply should be turned off to prevent accidental contact. Keep MIG Guns, electrode holders, TIG torches, Plasma torches, and electrodes away from moisture and water. See safety and operating references 1, 2, and 8.

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH

Ventilation must be adequate to remove smoke, fumes, and gases during operation to protect operators and others in the area. Vapors of chlorinated solvents can form the toxic gas “Phosgene” when exposed to ultraviolet radiation from an electric arc. All solvents, degreasers, and potential sources of these vapors must be removed from the operating area. Use air- supplied respirators if ventilation is not adequate to remove all fumes and gases. Oxygen supports, and vigorously accelerates fire and should never be used for ventilation. See safety and operating references 1, 2, 3, and 4.

ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN

Welding and cutting processes produce extreme localized heat and strong ultraviolet rays. Never attempt to weld/cut without a federally compliant welding helmet with the proper lens. A number 12 to 14 shade filter lens provides the best protection against arc radiation. When in a confined area, prevent the reflected arc rays from entering around the helmet. Approved shielding curtains and appropriate goggles should be used to provide protection to others in the surrounding area. Skin should be protected from arc rays, heat, and molten metal. Always wear protective gloves and clothing. All pockets should be closed and cuffs sewn shut.

Leather aprons, sleeves, leggings, etc. should be worn for out-of-position welding and cutting, or for heavy operations using large electrodes. Hightop work shoes provide adequate protection from foot burns. For added protection, use leather spats. Flammable hair preparations should not be used when welding/cutting. Wear ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in an individual booth painted with a low reflective material such as zinc oxide. See safety and operating references 1, 2, and 3.

WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS

Combustibles reached by the arc, flame, flying sparks, hot slag, and heated materials can cause fire and explosions. Remove combustibles from the work area and/or provide a fire watch. Avoid oily or greasy clothing as a spark may ignite them. Have a fire extinguisher nearby, and know how to use it. If welding/cutting is to be done on a metal wall, partition, ceiling, or roof, precautions must be taken to prevent ignition of nearby combustibles on the other side.

Do not weld/cut containers that have held combustibles. All hollow spaces, cavities, and containers should be vented prior to welding/cutting to permit the escape of air or gases. Purging with inert gas is recommended. Never use oxygen in a welding torch. Use only inert gases or inert gas mixes as required by the process. Use of combustible compressed gases can cause explosions resulting in personal injury or death. Arcing against any compressed gas cylinder can cause cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.

PROCESS FUNDAMENTALS

The SLICE Exothermic Cutting process uses an exothermic chemical reaction that burns, melts or vaporizes most materials. The reaction begins with an electrical arc or alternate energy source that causes a steel cutting rod to burn. Oxygen flows through the center of the rod. Because of the rod’s design, the burning makes excess heat (“exo – thermic”) which cuts the workpiece. Once started, the burn will continue as long as oxygen flows through the rod. The heat created melts the material being cut. The velocity of oxygen through the rod blows the molten material away, creating the kerf or cut line.

This arc ignition process led to invention of the oxy-arc torch and design of equipment for underwater construction and salvage. The electrical arc that starts the burn can be from a welding power source that delivers at least 100 amps, a 12-volt lead acid or similar low-impedance battery. The cutting process can run without power, using the heat of the reaction only, or with power, cutting with an electrical arc from a welding power source providing more heat.

HISTORY

The exothermic cutting rod is a small oxygen lance. A prime example of the combustion triangle is one side being fuel (the steel lance); the oxygen source (pure oxygen being forced through the lance); the heat of combustion (some external source of heat). However, when the lance pierces a slag puddle, the puddle becomes the source of heat until the lance is withdrawn, at which time burning stops.

In 1888, a published paper described passing oxygen through a steel tube and heating the tube to a bright red. Heat resulted. In 1901, Ernst Henner filed a German patent on an early oxygen lance made of two concentric tubes. In 1902, documentation shows that the oxygen lance replaced oil and gas torches for opening furnace taps in steel blast furnaces. The oxygen lance has since been used to cut rocks and concrete structures. An example is cutting up reinforced concrete structures such as bunker emplacements and tank traps built in Europe during World War II. An ideal way to start the lance, workers found, was to use a welding power source on conductive material to strike an arc and start the burn. This process worked well in construction, even in mud and water.

Around 1940, the burning bar or exothermic lance was first marketed as a cutting tool. A flexible version made of an insulated cable was introduced around 1960. Not until the early 1980’s were smaller burning bars designed for hand torch use, above and below water. A one-piece unit now allows for adequate rod surface exposure to an oxygen supply for exothermic cutting. Arcair, an ESAB brand, is a world leader in metal removal and cutting and sells this exothermic cutting equipment under the trade name Arcair SLICE.

EQUIPMENT

SLICE Torch

The SLICE Torch, a gun-shaped tool, provides a means of gripping the rod and supplying the oxygen and power to the cutting rod. The basic torch includes 10 ft. (3.05 m) of power cable and oxygen hose. The power cable can carry 200 amps in a power cutting operation. The oxygen hose includes a standard size oxygen fitting and is ready to be connected to the user’s oxygen regulator. This standard torch has a flexible hand shield which is easily replaceable if damaged, plus the torch is molded from a super tough Thermo plastic.

An optional 6″ (152 mm) collet extension and 6″ (152 mm) diameter extension shield is available to help reduce torch wear or damage when piercing. Also available is a 3/8″ (9.5 mm) adapter kit consisting of a collet chuck, Collet Nut, washer, and flashback arrestor needed to adapt the torch for using the 3/8″ (9.5 mm) diameter cutting rods.

SLICE Striker

A SLICE Striker is available for cutting without power. The striker is an insulated piece of copper plate with a serrated surface. By scratching the rod against the copper plate an arc is initiated and the cutting process begins. Striker wear can be extended by using the smallest exposed portion of the copper plate and gradually increasing.

• The SLICE striker comes standard with a 10 ft. (3.05 m) cable.

SLICE Components

Charging the Ignition Source

There are 3 LEDs on the Ignition Source panel (FAULT, CHARGING, and CHARGED). Fully charged status will display all LEDs green. For explanation of LED readouts refer to Section 9.2 Ignition Source LED Display Guide. The AC/DC Power Adapter (p/n 96-076-043) is required to complete these steps.

NOTE

It is recommended that the unit be recharged after every use or whenever the Charge Status LEDs shows 50% or less.

Charging the Ignition Source:

1. Press the TEST button on the Ignition Source panel to check status. If the LEDs do not present all green LEDs then proceed with the steps below.
2. Insert the AC/DC Power Adapter Output connector into the DC Input socket on the Ignition Source panel and plug the Power Adapter input cord into a 120 V, 60Hz or 240 V 50Hz wall outlet.
3. Keep the unit plugged in until fully charged. Charging time can be between 2-5 hours. On the Ignition Source panel amber LEDs will display when fully charged.
4. Disconnect the AC/DC Power Adapter connector from the Ignition Source and push the Test button to confirm full charge status. All the LEDs will display green.

CUTTING DATA

The following chart helps determine the best settings for a specific use as a result of extensive laboratory testing of the SLICE Equipment to determine the best cutting rates. Actual cutting results obtained in the field vary due to conditions and experience of the user. Various usages of SLICE Equipment return various results. Adjust the settings for any use. Use the following chart as a guide.

Oxygen pressure of 80 psi (551.6 kPa) achieves the best cutting. Some operations may require higher or lower oxygen pressures – minimum 40 psi (275.8 kPa); maximum 100 psi (689.5 kPa). Amperage over 200 amps does not improve cutting speed. Find the right metal and thickness. For composites or unlisted metals, locate the listed type that most resembles the material to be cut.

NOTE

• All these cutting values are based on 1/4″ (6.4 mm) diameter fluxcoated rods. Cutting rates with 1/4″ (6.4 mm) bare rods are slightly less than the values listed in the chart.

OPERATION

SLICE Exothermic Cutting uses heat from a chemical reaction between a consumable steel rod and oxygen flowing through the rod. Test data show that little or no oxygen remains. The oxygen not used in the reaction blows the molten material out of the cut area. This action creates the kerf that allows cut progression.

Cutting without Power

Cutting without power uses the heat reaction from the rod and the oxygen to cut. To initiate this type of cutting, ignite the rod from a spark supplied by a 12-volt battery or by a welding power source capable of delivering a 100-amp surge. Once this spark has ignited the rod, the electrical path is broken and the heat of the reaction melts the material and cuts it.

Cutting without power can be done in remote areas. Support equipment and bulky power sources are not needed.

1. Connect the torch to either terminal of a 12-volt battery or constant-current welding power source, then connect the striker or a strike plate to the other terminal. If using a welding power source, set output level for 100 amps.
2. Turn ON the oxygen supply and adjust the regulator to the proper working pressure. Insert the cutting rod into the collet and tighten the Collet Nut.
3. Tap the cutting rod on a hard, ungrounded surface to seat the rod in the torch.
4. Depress the torch oxygen valve lever and check for oxygen leaks around the Collet Nut.
   • NOTE: If oxygen is leaking, repeat the procedure until no oxygen is leaking.
5. Put the torch in one hand and striker in the other. Depress the oxygen lever and touch the cutting rod to the striker.
6. Once the rod is ignited, remove the striker, then move the burning rod to the workpiece and begin cutting.
   • NOTE:  Hold the cutting rod at a 45° to 80° drag angle from the workpiece surface. The angle depends on the thickness and type of material being cut.
7. Make slight contact between the burning rod tip and the workpiece as the cut progresses.
   • This placement requires two motions:
   • Inward towards the workpiece as the rod is consumed
   • In the direction of cut

Use a protective lens shade #5 since there is no electrical arc.

Cutting with Power

Cutting with power requires an electrical arc from a welding power supply and increases the heat created exothermically. Almost all constant-current welding power supplies can be used in powered exothermic cutting. Cutting with power is faster than cutting without power.

CAUTION

Constant-voltage power supplies should not be used with exothermic cutting equipment. When the exothermic cutting rod contacts the workpiece, the power supply is dead shorted, causing maximum amperage output of the power supply. This surge can exceed the rated output of the machine and the recommended amperage for powered exothermic cutting.

1. Connect the torch to one terminal, then connect a welding ground clamp to the other terminal of a CC (Constant Current) welding power source.
2. Attach the ground clamp to the workpiece. Unlike other processes, this process uses either a welding power source set for DCEP (reverse polarity) or DCEN (straight polarity). AC (alternating current) power supplies can also be used without affecting cutting performance. Do not cut with power using a constant-potential power source.
3. Insert the cutting rod into the collet and tighten. Start the oxygen flow, touch the rod tip to the workpiece, and begin cutting. Hold the cutting rod at a 45° to 80° drag angle from the workpiece surface.
4. Depress the torch oxygen valve lever and check for oxygen leaks around the Collet Nut.
5. As the cut proceeds, make slight contact between the burning rod and the workpiece. This placement requires two motions:
   • Inward towards the workpiece as the rod is consumed
   • In the direction of cut

Use a protective lens shade #10 or higher to protect from arc flash.

Hole Piercing

Perform most piercing operations without power.

1. Remove the Collet Nut Assembly from the front of the torch and remove the brass collet, washer and spark arrestor from the torch.
2. Attach the Collet Extension Assembly to the front end of the torch and once tightened reinstall the spark arrestor, washer and brass collet into the assembly.
3. Slide the Extension Shield over the Collet Extension Assembly until it bottoms out against the metal ring on the assembly.
4. Reinstall the Collet Nut Assembly onto the Collet Extension Assembly.
5. Insert the SLICE cutting rod into the torch and tighten the Collet Nut Assembly. Tap the SLICE rod against the work surface and tighten the Collet Nut again, this ensures the cutting rod is seated against the rubber washer.
6. Ignite the cutting rod as explained in the “Cutting without Power” section.
7. Move the burning rod to the pierce point and, with the rod angled away from the operator, begin piercing the hole.
8. Once the hole is under way, bring the cutting rod perpendicular to the surface of the workpiece. Keep the cutting rod deep enough in the hole to feel slight resistance from the non-molten material at the base of the hole. Use a slight circular motion while piercing the hole to keep the rod free of molten material coming out of the hole.
9. Move the rod in and out of the hole occasionally to maintain an open path for the molten material.

CAUTION

The molten material travels back up the rod while piercing. Wear proper clothing for protection from the molten spray. Hold the torch at arm’s length to keep the operator as far away from the molten material as possible. An optional 6″ (152.4 mm) collet extension and extension shield are available for the SLICE cutting torch to protect the operator and torch.

NOTE

• Piercing in the flat position is more difficult than piercing horizontally. Piercing flat progresses more slowly. For example, piercing a hole in a floor is more difficult and slower than piercing a hole in a wall.

Copper and Copper Alloys

CUTTING: Because of the very rapid heat absorption of copper and its alloys, cut with power on these materials. Use a maximum of 300 amps since copper quickly absorbs the heat created from the exothermic reaction, reducing the effectiveness of the cutting process. Cutting with power releases more heat so it is possible to cut some copper pieces. The larger the size of the part the more difficult it is to cut. A sawing motion into the cut kerf speeds cutting. Brass, bronze and other alloys are slightly easier to cut, but these alloys should be cut using power, if possible.

PIERCING: Use power when piercing copper and its alloys. This results in extremely fast rod consumption. The higher the copper content of the part, the harder the material is to cut.

IMPORTANT PROCESS VARIABLES

Exothermic cutting is easier than most cutting processes. Certain variables reduce the efficiency of this process, resulting in poor cutting. The most important variables are listed and discussed below.

Oxygen Pressure

Oxygen maintains the exothermic burn and removes the molten material from the cut. Eighty psi (551.6 kPa) yields the most efficient cutting rates (amount of cut per inch of rod burned) on materials up to 3″ (76.2 mm) thick. Using pressures less than 80 psi (551.6 kPa) on such materials reduces cutting rates due to inadequate pressure to remove the molten material.

However, scarfing is most efficient using pressures under 80 psi (551.6 kPa). Lower pressures offer a more controllable scarfing action. With material thicker than 3″ (76.2 mm), pressures over 80 psi (551.6 kPa) can be used to give the oxygen enough velocity to blow away molten material at the bottom of the cut. Using higher pressures on thicker materials causes a more forceful oxygen jet and faster rod consumption. A sawing motion at 80 psi (551.6 kPa) or a larger diameter rod may help cut these materials more efficiently. When piercing, 80 psi (551.6 kPa) is the best pressure to use. To pierce, an operator should reduce the pressure slightly to control the distance the molten material travels. Once there is a hole, full pressure should be used.

The operator can vary pressure by using the torch’s oxygen lever. When the thickness of the material – usually more than 12″ (304.8 mm) – needs added pressure to blow the molten material out of a pierced hole, pressures above 80 psi (551.6 kPa) are used. This is the only exception. The SLICE cutting process uses standard industrial-grade oxygen to support the exothermic reaction and to remove molten metal. All SLICE equipment uses standard oxygen fittings. SLICE torches are equipped with 10 ft. (3.05 m) of 1/4″ (6.4 mm) I.D. oxygen hose. The usual operating pressure is 80 psi (551.6 kPa). Applications such as cutting material sections 3″ (76.2 mm) and thicker might require higher operating pressures. Pressures as low as 40 psi (275.8 kPa) have been used to do jobs such as washing off rivet heads and scarfing out small cracks for repair. The oxygen consumption rate for SLICE cutting rods at 80 psi (551.6 kPa) is 7 to 7.5 cfm (0.21 cmm) for the 1/4″ (6.4 mm) diameter cutting rods and 12 to 13 cfm (0.34 to 0.37 cmm) for the 3/8″ (95 mm) diameter cutting rods. This rate varies if a different operating pressure is used.

WARNING

DO NOT use compressed air for exothermic cutting. Compressed air does not contain enough oxygen to support the burn; therefore, impurities can damage or destroy the torch and components. The torch could burn from the inside or even explode from the buildup of dirt from the compressed air in the oxygen-supply tube and cause serious injury to the operator.

Amperage

Electrical current increases the heat from the reaction in exothermic cutting, allowing faster cutting. 200 amps yields the most efficient cutting rates with power. When cutting with power and using less than 200 amps, the amount of cut per minute will be lower. Amperage above 200 amps consumes the rod faster, reducing the cut per inch of rod burned. Exothermic cutting equipment uses around 200 amps. Exceeding this amperage could cause equipment damage. When cutting without power, current from the battery ignites the rod. To ignite the rod a surge of at least 100 amps is needed. If the battery has not been properly charged it will not have enough amperage to ignite the cutting rod.

Travel Speed

The cutting rod burns constantly without an electrical arc. Therefore, cut as fast as possible without losing the cut kerf. If the travel speed is too fast, the material will not cut completely through and molten slag will be blown back from the workpiece.

Electrode-To-Work Angle

The electrode-to-work angle is the most flexible process variable. However, use of an improper angle can cause reduced cutting efficiency. For most cutting jobs the ideal angle is between 45° and 80°. For thicker material, hold the rod closer to an 80° angle. The electrode-to-work angle is typically a drag angle – the rod is held so the tip of the burning rod is away from the direction of travel. Cutting sheet metal is one exception since it is usually faster and better controlled when the user keeps a 45° angle or slightly less, and pushes the rod in the direction of cut. Aluminum, regardless of its thickness, requires a 70° to 80° drag angle.

| 1.  Insufficient oxygen pressure being used.

2.  Rubber washer behind collet chuck worn and needs to be replaced.

3. Travel speed too fast.

Battery will only start a few rods before charge is depleted.

| 1.  Battery was not given sufficient time to recharge.

2.  Battery needs to be replaced.

3.  Battery left exposed to subfreezing temperatures.

Torch shield is being burnt off around Collet Nut.| 1.  Rod is not properly seated in torch. Refer to Section 6 on operating techniques to properly seat rod.

2.  Collet extension not used when piercing holes.

When piercing anything but copper and its alloys, the rod consumes extremely fast.| 1. Operator is piercing with power. All piercing operations except ones on copper and its alloys should be done without power.
