SECTION 2: 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 instruc-

tions 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 refer-

enced 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.

89250840

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.

SECTION 3: 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.

SECTION 4: EQUIPMENT

4.01 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.

4.02 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.

4.04 Cutting Rods

SLICE Cutting Rods are made of carbon steel, by rolling a steel strip into a rod, and are coated or

uncoated. The coating is made of arc stabilizers and a binder. Several advantages to using the

coated rods with power include:

• More efﬁcient cutting rates (more cut per inch of rod burnt and more cut per minute of burn time)

• Easier rod operation

• Protection from burning out on the side of the rod, especially when piercing

SECTION 5: 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 ux-

coated rods. Cutting rates with 1/4" (6.4 mm) bare rods are slightly

less than the values listed in the chart.

SECTION 6: 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.

6.01 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.

Figure 4: Cutting without Power

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.
