OPERATING INSTRUCTIONS

CONNECTING

1. Attach regulators to the oxygen and acetylene cyl-

inders. Follow all instructions supplied with your

regulators.

2. Attach oxygen and acetylene hoses to the regula-

tors and to the torch handle, after making sure all

metal seating surfaces are clean. Tighten all con-

nection nuts with a wrench.

3. Attach welding or heating head to the torch handle.

Tighten the connection nut with a wrench, but use

only slight force, since the threads have a low pitch

and excessive force may distort them.

4. Check throttle 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.

LIGHTING AND FLAME ADJUSTMENT

1. Open the torch oxygen valve one-quarter of a turn.

2. Open the torch fuel gas valve one-half turn (two full

turns if low-pressure acetylene is being used) and

light the gas at the tip with a friction lighter. DO NOT

USE A MATCH. Use of a match can seriously burn

your hand.

3. Open the oxygen valve wide and adjust the fuel gas

valve to secure the desired flame. If a softer flame

is desired, reduce the oxygen flow by throttling the

oxygen valve and then readjust the fuel gas valve.

NOTE: When operating with a very soft flame, the

welding head will tend to heat up and transfer

some of this heat to the torch handle. This may

create some discomfort to the operator.

Be sure this information reaches the operator.

You can get extra copies through your supplier.

These Safety Precautions are for your protection. They sum-

marize precautionary information from the references listed

in Additional Safety Information section. Before performing any

installation or operating procedures, be sure to read and fol-

low the safety precautions listed below as well as all other

manuals, material safety data sheets, labels, etc. Failure to ob-

serve 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 pro-

cesses 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 re-

quired.

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 non-

flammable partition or curtains.

5. Use goggles over safety glasses when chipping slag or grind-

ing. Chipped slag may be hot and can travel considerable dis-

tances. 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 non-

flammable covering. Combustible materials include wood,

cloth, sawdust, liquid and gas fuels, solvents, paints and coat-

ings, 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.

FUMES AND GASES - Fumes and gases, par-

ticularly in confined spaces, can cause dis-

comfort or injury. Do not breathe fumes or

gases from welding or cutting, Therefore:

1. Always provide adequate ventilation in the work area by natu-

ral 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 venti-

lation in the work area. Do not continue to operate if physical

discomfort persists.

3. Refer to ANSI/ASC Standard Z49.1 listed below for specific

ventilation recommendations.

4. WARNING: 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 §25249.5 et seq.)

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 mis-

handled, can rupture or explode violently. Sudden

rupture of a cylinder, valve or relief device can in-

jure or kill you. Therefore:

1. Use the proper gas for the process and use the proper pres-

sure reducing regulator designed to operate from the com-

pressed gas cylinder. Do not use adaptors to mount the regu-

lator on the cylinder. Maintain hoses and fittings in good con-

dition. Follow manufacturer’s operating instructions for mount-

ing 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 weld-

ing, cutting, or gouging operation. Never strike an arc on a

cylinder.

5. For additional information, refer to CGA Standard P-1, “Pre-

cautions for Safe Handling of Compressed Gases in Cylin-

ders:, which is available from the Compressed Gas Associa-

tion, 1235 Jefferson Davis Highway, Arlington, VA 22202.

SAFETY PRECAUTIONS

any doubt about the adequacy of gas flows, use an

oxygen test gauge adaptor (P/N 07X17) and either

the acetylene (P/N 262510) or fuel gas (P/N 639422)

test gauge adaptor while the torch is operating to

make sure that the recommended operating pres-

sures are available at the torch inlet.

7. Manifold two or more fuel gas cylinders to assure

adequate supply of fuel gas. The tables show the

number of commonly used cylinders recommended

for manifolding when using larger heads. If using

other cylinders or gases, check with your fuel gas

supplier for recommended withdrawal rate informa-

tion.

8. In the event of a flashback, immediately close both

oxygen and fuel gas valves on the torch (preferably

oxygen valve first). For greater protection, install

1/4-turn quick shut off valve (P/N 999306) on the

torch oxygen hose connection.

** Based on max. continuous withdrawal rate of 65 cfh for 100 lb. cylinder,

1/2 full @ 70° F.

Withdrawal rate will increase with wind velocity and intermittent usage;

reduce with lower temperature.

9. If the inner cone of the flame appears too short

(less than 1/4-in.), you are lacking fuel gas and the

head will tend to overheat. Recheck the above

precaution with your set up.

10. Do not bring the head too close to the work. Maintain

a distance of at least 1/4-in. between tip and work.

RECOMMENDED HOSE SIZES

Oxygen, Acetylene (medium-pressure) and Natural

Gas (at pipeline pressure over 5 psig): With head

sizes 4-30, 1/4-in. or 3/8-in. I.D. With head sizes 55 and

larger, 3/8-in I.D.

Acetylene (low-pressure) and Natural Gas (at pipe-

line pressure below 5 psi): With head sizes 4-70, 3/

8-in. I.D. hose. Head sizes 100-250, 1/2-in. hose. Do

not use over 25 feet of hose.

SHUTTING OFF

Close the fuel gas valve first, then the oxygen valve.

If operations are to be stopped for a half-hour or more,

all pressure should be released from the torch hoses,

and regulators by doing the following:

1. Close each cylinder or station valve.

2. Open torch valves.

3. After relieving the gases, back out the pressure-

adjusting screw of each regulator and close the

torch valves.

IMPORTANT OPERATING NOTES

1. Do not attempt to operate heads size 100 or larger

from a low-pressure acetylene supply (less than 5

psig).

2. Head size number of each welding and heating

head indicates the rated acetylene capacity in

cubic feet/hour (cfh). For example, No. 55A re-

quires about 55 cfh of acetylene at normal operat-

ing pressure. However, on heating heads designed

for other fuel gases, the size indicates the approxi-

mate equivalent heating capacity in terms of acety-

lene flow. For example, No. 100A and No. 100FG

provide the same average heating output (147,000

Btu/hr) but No. 100FG head really requires about

62 cfh of FG-2, 57 cfh of propane, or 147 cfh of

natural gas.

For consumption purposes, the following are the oxy-

gen/fuel gas ratios normally required for welding and

heating:

1.1 to 1.5 cfh oxygen/1.0 cfh acetylene

3.2 to 3.6 cfh oxygen/1.0 cfh FG-2

3.5 to 4.5 cfh oxygen/1.0 cfh propane

1.7 to 2.0 cfh oxygen/1.0 cfh natural gas.

PRECAUTIONS - NO. 55 and LARGER HEADS

Large welding and heating heads (No. 55 and above)

require high flow of oxygen and fuel gas for proper

operation. Failure to follow the following precau-

tions can result in serious overheating, flashback,

and possible operator injury.

1. Read and understand the operating instructions

packed with your torch as well as these precautions

before lighting up the welding or heating head.

2. Always operate with oxygen and fuel gas pressures

given in the tables.

3. Do NOT use hose line reverse flow check valves

when using No. 100 or larger welding or heating

head.

4. Use 3/8-in. I.D. hoses when using No. 55 or larger

welding or heating head.

5. Do NOT use whip hose, hose splices, nor hose

nipples smaller than 1/4-in. I.D. (“B”-size).

6. If using hose lengths greater than 25-ft., or if there is

TESTING FOR LEAKS

Every welding and cutting outfit should be thoroughly

tested for leaks after it is first hooked up, and at regular

intervals thereafter. After all connections have been

made, make sure both valves on the torch handle are

closed. Then turn in the regulator pressure-adjusting

screw until the oxygen delivery-pressure gauge regis-

ters 50 psi, the acetylene delivery-pressure gauge

registers 10 psi. Using Leak Test Solution suitable for

oxygen service, such as P/N 998771 (8 oz. container),

check for leaks at the cylinder valves, the cylinder-to-

regulator connections, the regulator-to-hose connec-

tions, and the hose-to-torch connections. If bubbling at

any point indicates leakage, tighten the connection. If

this does not stop the leakage, close the appropriate

cylinder valve, open the torch valve to remove all

pressure from the line, and finally release the regulator

pressure-adjusting screw by turning it counterclock-

wise. Then break the leaky connection, wipe metal

seating surfaces with a clean, dry cloth, and examine

them for nicks and scratches. Remake the connection(s)

and retest. Do not try to light the torch until you are

satisfied that all connections are gas-tight.

After lighting the torch, and adjusting the flames, use

leak test solution to check for leakage at all torch valves,

and at the connection between the torch handle and the

welding head or cutting attachment.

OPERATING PRECAUTIONS

Flow: There must be proper flow of gases for safe

operation and full performance. This requires the fol-

lowing three conditions: (1) the regulators that deter-

mine the inlet pressure to the hoses must be set to the

correct pressure: (2) the hoses and their connectors

must have adequate capacity for the job (hoses that

are too long, too small or have connectors with small

passageways can cause problems); and (3) the throttle

valves on the torch must be adjusted with the proce-

dure shown in these instructions.

Note: Items (1) and (2) can be checked by measuring

the gas pressures

at the torch. Gauge adaptors

are available for this purpose.

Backfire: Improper operation of the torch may cause

the flame to go out with a loud ‘pop’. Such a backfire

may be caused by contact of the tip with the work,

spatter from the tip, or by attempting to operate with too

small a flame. After a backfire, you can normally relight

the flame immediately. If backfires occur repeatedly,

shut off the torch. Then reopen the oxygen valve,

check for correct oxygen pressure, and test for leak-

age at the welding head connection nut and tip connec-

tion nut. If there is leakage at either point, correct it (by

tightening the tip, or cleaning the seating surfaces on

the injector and in the torch body) before resuming

work.

Flashback: Under certain circumstances, the flame

may not ‘pop’ out (backfire) but instead burn back inside

the torch with a shrill hissing or squeal. This is called a

‘flashback’. A flashback should never occur if (1) the

equipment is in good condition; (2) preheat ports on

cutting nozzles or welding tips are cleaned frequently;

(3) operating pressures are correct; and (4) throttle

valves are adjusted properly. Should a flashback occur,

IMMEDIATELY shut off the torch. Allow it to cool off for

at least a minute. Then check your nozzle or tip, gas

pressure, readjust regulators if necessary, and relight

the torch. If flashback recurs, send the torch handle and

welding head or cutting attachment to ESAB

Remanufacturing Center or to your distributor for re-

pair.

MAINTENANCE INSTRUCTIONS

For all repairs other than those covered below,

send the apparatus to your welding equipment

distributor or to ESAB Remanufacturing Center,

Ebenezer Road, Florence, SC 29501. Improperly

repaired apparatus is hazardous.

Torch Valves: Leakage around either throttle valve

can usually be corrected by tightening the packing nut

slightly. If it cannot be corrected, replace throttle valve

assembly.

If either valve fails to shut off completely, remove the

throttle valve assembly from torch and wipe the ball

seat on the end of the stem with a clean cloth. Then

reinstall the valve and tighten it heavily several times. If

this does not eliminate leakage, try a new throttle valve

assembly. If then the valve does not shut off completely,

send the torch handle to a repair station for reseating of

the body.

Tip Cleaning: If a welding tip produces a distorted,

irregular flame, clean the tip with an OXWELD tip

cleaner, or the correct size twist drill (see table on page

4). Do not attempt to clean with any other type of tool.

When using cleaning drills, push the drill straight in and

out; do not twist.

Injector Cleaning: The relative small central oxygen

orifice in an injector may become partially clogged with

small particles conveyed in the oxygen stream or

carbon particles produced by backfires. To clean or

replace an injector, remove it from the mixer tube (after

removing the connection nut retaining ring and sliding

the nut forward) by grasping it with a pair of pliers

between the seating surfaces and pulling it straight out

with steady force. Take great care not to mar the

injector seats or O-rings with the pliers. Clean the

central (oxygen) orifice with the correct size twist drill

(see table on page 4). Use no other tools. Replace O-

rings if damaged or worn. Replace the injector if its rear

seats are marred. When reinstalling injector, be sure to

push it in until its retaining O-ring is firmly seated in the

mixer tube.
