The cutting torch covered by these instructions is listed by third party listed, and when they are used in the gas
service for which they are designed and listed. The use of other parts that cause damage for failure to the equipment
will void the manufacturer’s warranty.
OPERA TING INSTRUCTIONS
CONNECTING
1. Attach regulators to the oxygen and fuel gas cylinders. Follow all instructions supplied with the regulators.
2. Attach oxygen and fuel gas hoses to the regulators
and to the torch, after making sure all metal seating
surfaces are clean. Tighten all connection nut s with
a wrench.
3. Attach nozzle to torch head, and tighten connection
nut with a wrench.
4. Check the valve packing nuts for tightness.
Flashbacks can cause serious burns.
Be sure gas flow is sufficient for head or nozzle size.
Adjust regulators for proper psig pressures.
Adjust throttle valves properly.
Keep torch in good repair.
DO NOT throttle back gases to use large head or nozzle
on thin material.
ADJUSTING GAS PRESSURES
Fuel Gas: Open the fuel gas valve about one turn. Turn
in the pressure-adjusting screw on the fuel gas regulator until its delivery-pressure gauge registers the desired
pressure (see cutting chart on page 4). Then immediately close the fuel gas valve.
Oxygen: Open the cutting oxygen valve by depressing
its valve lever fully . Turn in the pressure-adjusting screws
on the oxygen regulator until its delivery-pressure gauge
registers the desired pressure (see cutting chart on page
4). Then release the cutting oxygen lever .
NOTE: When gaugeless regulators are used, do not
open torch valves. Merely turn in the pressureadjusting screws to the desired pressures as
indicated on the scales of regulator caps.
TESTING FOR LEAKS
Every cutting outfit should be thoroughly tested for leaks
after it is first hooked up, and at regular intervals thereafter. Af ter all connections have been made, make sure
all valves on the torch handle are closed. Then turn in
Be sure this information reaches the operator.
You can get extra copies through your supplier.

SAFETY PRECAUTIONS
These Safety Precautions are for your protection. They summarize precautionary information from the references listed
in Additional Safety Information section. Before performing any
installation or operating procedures, be sure to read and follow the safety precautions listed below as well as all other
manuals, material safety data sheets, labels, etc. Failure to observe Safety Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS - Some
welding, cutting and gouging processes are
noisy and require ear protection. Hot metal can
cause skin burns and heat rays may injure
eyes. Training in the proper use of the processes and equipment is essential to prevent
accidents. Also:
1. Always wear safety glasses with side shields in any work area,
even if welding helmets, face shields, or goggles are also required.
2. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt,
cuffless trousers, high-topped shoes, and a welding helmet or
cap for hair protection, to protect against hot sparks and hot
metal. A flameproof apron may also be desirable as protection
against radiated heat and sparks.
3. Hot sparks or metal can lodge in rolled up sleeves, trousers
cuffs, or pockets. Sleeves and collars should be kept buttoned,
and open pockets eliminated from the front of clothing.
4. Protect other personnel from hot sparks with a suitable nonflammable partition or curtains.
5. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and can travel considerable distances. Bystanders should also wear goggles over safety
glasses.
FIRES AND EXPLOSIONS - Heat from a flame
can act as an ignition source. Hot slag or sparks
can also cause fires or explosions. Therefore:
1. Remove all combustible materials well away from the work
area or completely cover the materials with a protective nonflammable covering. Combustible materials include wood,
cloth, sawdust, liquid and gas fuels, solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or crevices in
floors or wall openings and cause a hidden smoldering fire on
the floor below. Make certain that such openings are protected
from hot sparks and metal.
3. Do not weld, cut, or perform any other hot work on materials,
containers, or piping until it has been completely cleaned so
that no substances on the material can produce flammable or
toxic vapors. Do not do hot work on closed containers. They
may explode.
4. Have fire extinguishing equipment handy for instant use, such
as a garden hose, a pail of water or sand, or portable fire
extinguisher. Be sure you are trained in its use.
5. After completing operations, inspect the work area to be sure
that there are no hot sparks or hot metal which could cause a
later fire. Use fire watchers when necessary.
6. For additional information, refer to NFPA Standard 51B, Fire
Prevention in Use of Cutting and Welding Processes, which
is available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
3. Refer to ANSI/ASC Standard Z49.1 listed below for specific
ventilation recommendations.
EQUIPMENT MAINTENANCE - Faulty or improperly
maintained equipment, such as torches, hoses and
regulators, can result in poor work, but even more
important, it can cause injury or death through fires.
Therefore:
1. Always have qualified personnel perform the installation,
troubleshooting, and maintenance work. Do not operate or
repair any equipment unless you are qualified to do so.
2. Keep all oxy-fuel equipment free of grease or oil. Grease, oil,
and other similar combustible materials, when ignited, can burn
violently in the presence of oxygen.
3. Do not abuse any equipment or accessories. Keep equipment
away from heat and wet conditions, oil or grease, corrosive
atmospheres and inclement weather.
4. Keep all safety devices in position and in good repair.
5. Use equipment for its intended purpose. Do not modify it in
any manner.
GAS CYLINDER HANDLING - Gas cylinders, if
mishandled, can rupture or explode violently.
Sudden rupture of a cylinder, valve or relief device can injure or kill you. Therefore:
1. Use the proper gas for the process and use the proper pressure reducing regulator designed to operate from the compressed gas cylinder. Do not use adaptors to mount the regulator on the cylinder. Maintain hoses and fittings in good condition. Follow manufacturers operating instructions for mounting the regulator to the gas cylinder.
2. Always secure cylinders in an upright position by chain or strap
to suitable hand trucks, benches, walls, post, or racks. Never
secure cylinders to work tables or fixtures where they may
become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have the valve
protection cap in place on top of the cylinder if no regulators is
installed. Secure and move cylinders by using suitable hand
trucks. Avoid rough handling of cylinders.
4. Locate cylinders away from heat, sparks, or flame of a welding, cutting, or gouging operation. Never strike an arc on a
cylinder.
5. For additional information, refer to CGA Standard P-1, Precautions for Safe Handling of Compressed Gases in Cylinders:, which is available from the Compressed Gas Association, 1235 Jefferson Davis Highway, Arlington, VA 22202.
ADDITIONAL SAFETY INFORMATION - For more information on safe practices for oxy-fuel welding and
cutting equipment, ask your distributor for a copy of
Precautions and Safe Practices for Gas Welding, Cutting, and Heating, Form 2035. Gas apparatus safety
guidelines are also available on video cassettes from
your distributor.
The following publications, which are available from the American
Welding Society, 550 N.W. LeJuene Road, Miami, FL 33126, are
recommended to you:
1. ANSI/AWS Z49.1 - Safety in Welding and Cutting.
2. AWS F4.1 - Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That
Have Held Hazardous Substances/
3. AWS SP - Safe Practices - Reprint, Welding Handbook.
FUMES AND GASES - Fumes and gases, particularly in confined spaces, can cause discomfort or injury. Do not breathe fumes or
gases from welding or cutting, Therefore:
1. Always provide adequate ventilation in the work area by natural or mechanical ventilation means. Do not weld, cut, or gouge
on materials such as galvanized steel, stainless steel, copper,
zinc, lead, beryllium, or cadmium unless positive mechanical
ventilation is provided. Do not breathe fumes and gases from
these materials.
2. If you develop momentary eye, nose, or throat irritation while
operating, this is an indication that ventilation is not adequate.
Stop work at once and take necessary steps to improve ventilation in the work area. Do not continue to operate if physical
discomfort persists.
