OPERATING INSTRUCTIONS
WARNING
The SCT-1500 can be used with any fuel gas. Be sure gas
ow is sucient for 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 nozzle on thin material.
CONNECTING
1. Attach regulator to the oxygen cylinder or station valve;
attach fuel gas regulator to cylinder or station valve
unless fuel gas is to be supplied through a hydraulic
or check valve from a pipeline at desired pressure.
2. Attach oxygen hose to the oxygen regulator; attach
fuel gas hose to the fuel gas station valve or regulator.
Attach both hoses to torch. Tighten all connections nuts
with a wrench.
3. Attach nozzle to torch head, and tighten connection
nut with a wrench.
4. Check throttle valve packing nuts for tightness.
ADJUSTING GAS PRESSURES
Fuel Gas: If fuel gas is supplied from a station outlet without
a regulator, merely open the station valve. If fuel gas is being
supplied through a station or cylinder regulator, open the
fuel gas valve on the torch, turn in the pressure-adjusting
screw on the regulator until the regulator deliver-pressure
gauge indicates the desired pressure (see 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 screw until
the regulator 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 pressure-adjusting
screws to the desired pressures as indicated on the
scales of the regulator caps.

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 ameproof gauntlet type gloves, heavy long-sleeve shirt, culess trousers, high-topped shoes, and a welding helmet or cap for hair
protection, to protect against hot sparks and hot metal. A ameproof
apron may also be desirable as protection against radiated heat and
sparks.
3. Hot sparks or metal can lodge in rolled up sleeves, trousers cus,
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-ammable 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 ame can act as an ignition
source. Hot slag or sparks can also cause res or explosions. Therefore:
1. Remove all combustible materials well away from
the work area or completely cover the materials with a
protective non-ammable 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 oors or
wall openings and cause a hidden smoldering re on the oor 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 ammable or toxic vapors.
Do not do hot work on closed containers. They may explode.
4. Have re extinguishing equipment handy for instant use, such as a
garden hose, a pail of water or sand, or portable re 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 re.
Use re 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, particularly in conned spaces,
can cause discomfort or injury. Do not breathe fumes or gases from
welding or cutting, Therefore:
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 res.
Therefore:
1. Always have qualied personnel perform the installation,
troubleshooting, and maintenance work. Do not operate
or repair any equipment unless you are qualied 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 ttings
in good condition. Follow manufacturer’s 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 xtures where they may become part of
an electrical circuit.
3. When not in use, keep cylinder valves closed. Have the valve protec-
tion 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 ame of a welding, cut-
ting, 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 Jeerson 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

TESTING FOR LEAKS
Every cutting outt should be thoroughly tested for leaks
after it is rst hooked up, and at regular intervals thereafter.
After all connections have been made, make sure all valves
on the torch handle are closed. Then adjust regulators, or
open station valves, to apply 60 psi oxygen pressure and
up to 10 psi fuel gas pressure on the hoses.
Using Leak Test Solution (P/N 998771), or any other solution suitable for oxygen service, check for leaks at the
cylinder valves, the cylinder-to-regulator connections, the
regulator-to-hose connections, 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 corresponding torch
valve to remove all pressure from the line, and nally release the regulator pressure-adjusting screw by turning it
counterclockwise; 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 satised
that all connections are gas-tight.
After lighting the torch and adjusting the ames, use leak
test solution to check for leakage at all torch valves and at
the nozzle nut.
LIGHTING AND FLAME ADJUSTMENT
1. Open the preheat oxygen valve on the torch about 1/8
turn.
2. Open the fuel gas valve on the torch about 1/8 turn and
light the gas at the nozzle with a friction lighter. DO NOT
USE A MATCH. Use of a match can seriously burn your
hand.
3. If using acetylene, open fuel gas valve until preheat
ames leave the end of the nozzle and then close just
enough to return the ames to the nozzle. Depress
lever to open cutting oxygen valve and then readjust
preheat ames to neutral by opening preheat oxygen
valve gradually. If using FG-2 or other fuel gases but
acetylene, open fuel gas valve until ames just starts
to leave the end of the nozzle and then open the preheat oxygen valve until the ames are at their shortest
length. Depress the cutting oxygen valve lever and then
readjust the preheat ames to the shortest length by
opening the preheat oxygen valve gradually. The above
procedure usually provides adequate preheat or the
nozzle in use. If desiring to change the preheat ames,
always hold the cutting oxygen valve open while readjusting the preheat oxygen and fuel gas valves.
NOTE: Because of the several factors involved (injector,
nozzle size, gas pressures) the adjustment procedures
given above do not apply in all situations. However,
this is a good rule-of-thumb if you want preheat
ames at maximum eectiveness. You should usually be able to keep one preheat valve wide open if
regulator oxygen pressure has been set correctly for
the nozzle in use.
SHUTTING OFF
Release the cutting oxygen valve lever. Then close the fuel
gas valve, and nally the preheat oxygen valve.
If operations are to be stopped for 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.
OPERATING PRECAUTIONS
Backre: Improper operation of the torch may cause the
ames to go out with a loud “pop”. Such a backre may be
caused by contact of nozzle with the work, by spatter from
the work, by the use of incorrect gas pressures, or by leakage at the cutting nozzle seats due to dirt or nicks on seats
or to a loose nozzle nut.
Flashback: Under certain circumstances, the ame may not
“pop” out (backre) but instead burn back inside the torch
with a shrill hissing or squeal. This is called a “ashback”. A
ashback 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
ashback occur, IMMEDIATELY shut o the torch. Allow it to
cool o for at least a minute. Then check your nozzle or tip,
gas pressure, readjust regulators if necessary, and relight the
torch. If ashback recurs, send the torch to your distributor
or to ESAB Remanufacturing Center, 411 S. Ebenezer Road,
Florence, SC 29501 for repair.

GENERAL NOTES:
OPERATING DATA, CLEANING DATA, AND PART NUMBERS
1. Pressures given are measured at the torch; therefore,
pressure drop through hose should be considered
when setting pressure at the regulator. Generally,
1/4-in. hoses up to 25-ft. long are adequate for cutting
2. The table shows average values based on typical conditions. The type and quality of steel, its surface condition,
the purity of the oxygen, etc. will always have a bearing
on the end results.
steel up to 4-in. thick. If longer hoses are required and
if cutting thicker steel, 3/8-in. hoses should be used. If
using low-pressure fuel gas, 3/8-in. fuel gas hose should
be used for all cutting operations.

MAINTENANCE INSTRUCTIONS
For all repairs other than those covered below, send the apparatus to the nearest ESAB distributor or to ESAB Remanufacturing
Center, 411 S. Ebenezer Road, Florence, SC 29501. Improperly
repaired apparatus is hazardous.
Preheat Valves: Leakage around either throttle valve can usually
be corrected by tightening packing nut slightly. If this does not
stop the leakage, replace the valve assembly.
If either preheat valve fails to shut o completely, remove the valve
assembly from the torch. With clean cloth, wipe the ball in the end
of the stem. Then reinsert valve assembly and tighten it several
times with maximum force. If this does not eliminate leakage, try a
new valve assembly. If then the valve does not shut o completely,
send the torch to a repair station for reseating of the body.
After installing a new throttle valve assembly, tighten the packing
nut until the valve can be turned only with great diculty, and set
the unit aside, for three or four hours at least, to set the packing.
Then back o the packing nut until the valve turns readily.
Cutting Valve: If leakage is detected between the cutting valve
stem cap and the valve, or if the cutting valve fails to shut o
completely, remove cutting valve lever and then unscrew the
valve assembly (08M05), You may either replace the entire valve
assembly or disassemble the valve assembly to replace valve
stem (19216), seat (19215), and O-ring (14K11). If the latter,
unscrew the valve stem from the cap (824). Using the new valve
stem, seat, and O-ring, reassemble the valve as follows:
1. Place the new O-ring and retaining washer (10K23) in
the valve nut (19217).
2. Insert the valve spring (23K07) behind the retaining
washer and hold in place rmly while inserting new
seat, and then new valve stem through the valve nut
and O-ring.
3. Screw the valve stem into the valve stem cap rmly.
4. Replace O-ring (14K07) about the seat of the valve
nut if O-ring appears distorted.
5. Screw the entire assembly into the torch body and
tighten rmly with a wrench. Reassemble the cutting
valve lever to the torch body.
Cleaning Cutting Nozzles: Cutting nozzle orices should be
cleaned by hand using OXWELD tip cleaners, whenever a ame
distortion is noticed. Maintaining clean orices is highly recommended for reducing any incidence of ashbacks. If you do not
have tip cleaners, twist drills of the correct sizes (see table on pg.
4) may be used. Insert the drill carefully, and push it back and forth.
DO NOT TWIST THE DRILL.
To clean the preheat slots on internal nozzles, remove the external
sleeve and use a soft bristled brush (750F99).
