Be sure this information reaches the operator.
You can get extra copies through your supplier.
DO NOT use torch with any fuel gas except natural
gas or propane. Using other fuel gases can over-
heat and damage the torch which can cause per-
sonal injury.
The PM-GST Cutting Torch is a post mixed design per-
mitting the oxygen and fuel gas to be mixed externally
near the exit end of the torch. No internal mixing of the
combustibles occurs in the torch. Highly efficient mixing
occurs due to the distribution of preheat gases and
shielding gases around the cutting oxygen stream. This
produces an extraordinarily long high-heat zone permit-
ting high standoff of torch to workpiece, thus increasing
the life of the torch and nozzle.
The PM-GST was designed for manual cutting opera-
tions that require torch to be in the stand-by pilot flame
mode ready for immediate use, such as emergency hot
cast billet cutting. The PM-GST (Post-Mix-Gas Saving
Torch) provides substantial gas savings in pilot mode
but remains ready for cutting without the operator hav-
ing to light the torch.
The PM-GST Cutting Torch can be used on hot or cold
material and because of intense preheat capability pro-
vides extremely fast starts and cutting speeds.
DO NOT position the torch with the pilot flame ig-
nited close to any combustible materials. When pi-
lot flame is ignited torch must be held firmly by the
operator or in a stand-by holding fixture.
OPERATING INSTRUCTIONS

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.
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 de-
vice can injure 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
3
NOTE: The optimal amount of preheat oxygen is auto-
matically regulated by the torch. The pilot oxy-
gen valve is used only to adjust the pilot flame.
Cutting: Preheating is done while cutting lever is fully
depressed. Position torch on the far side of steel to be
cut. While maintaining at least 4 in. nozzle-to-work stand-
off, position the flame on the edge of the steel. Pull torch
towards you to begin cutting.
NOTE: The flame is hottest at the edge of the cutting
oxygen stream. Placing the edge of the cutting
oxygen stream on the edge of the steel will give
the fastest starts.
Torch head, nozzle, and nozzle nut become VERY
hot while pilot flame is on and remain hot for sev-
eral minutes after torch is turned off. Do NOT allow
hot torch to contact anything flammable.
SHUTTING OFF
1. Release cutting oxygen lever.
2. Close the pilot oxygen and fuel gas valves.
If operations are to be stopped for a half-hour or more,
pressure should be released from all regulators in the
following order:
1. Close station valve of each gas supply.
2. Open all torch shutoff valves.
3. When pressure on each regulator gauge drops down
to zero, back out regulator pressure-adjusting screw.
4. Close torch shutoff valves.
OPERATING PRECAUTIONS
Flow: There must be proper flow of gases for safe op-
eration and full performance. This requires the following
three conditions: (1) the regulators that determine 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 procedure 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 flames to go out with a loud “pop”. Such a backfire
may be caused by contact of nozzle with the work, by
the use of incorrect gas pressures or by leakage at the
cutting nozzle seats due to dirt or nicks on the seats or
to a loose nozzle nut.
ADJUSTING GAS PRESSURES
1. Depress the cutting lever fully. Adjust cutting oxy-
gen regulator to the desired pressure (see Figure 1)
compensating for any line loss to the torch through
the hose and valve. Then immediately release the
lever.
2. Adjust fuel gas regulator to provide 20 psig at the
torch with flow.
TESTING FOR LEAKS
The system should be thoroughly tested for leaks after
it is first hooked up, and at regular intervals thereafter.
With the system pressurized down to the shutoff valves,
apply Leak Test Solution suitable for oxygen service,
such as P/N 998771 (8 oz. container), on all joints and
connections. Bubbling of the solution indicates leakage.
If leakage is detected, tighten the connection. If this does
not stop leakage, then shut off the appropriate gas sup-
ply and open the torch valve to remove pressure from
the system. Break the leaky connection, wipe metal seat-
ing surface with a clean dry cloth, and examine them for
nicks and scratches. Remake the connection(s) and re-
test. 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 around hose connec-
tions at each valve and torch fitting.
LIGHTING AND FLAME ADJUSTMENT
Lighting Pilot Flame: Open fuel gas valve fully and light
the gas about 2 inches from the nozzle with a friction
lighter. DO NOT use a match. Use of a match can seri-
ously burn your hand. Slowly open the pilot oxygen valve
until the pilot flame is adjusted as desired. For best per-
formance, a flame extending just beyond the nozzle skirt
is recommended.
Cutting Flame Adjustment: While torch is lit in pilot
mode, point torch in a safe direction, hold torch firmly
and depress cutting lever fully. CAUTION: The torch will
tend to kick back from the force of the cutting oxygen.
Adjust fuel gas valve to give desired flame. Release cut-
ting lever to return to pilot mode. Depress cutting lever
several times, both slowly and quickly to ensure pilot
flame is set properly. If torch extinguishes itself when
lever is released, open pilot oxygen valve slightly to in-
crease pilot oxygen flow, relight torch and readjust pilot
oxygen valve.
stream of the regulator. Tighten the connecting nuts
firmly using two wrenches to prevent damage to the
torch.
3. Assemble desired nozzle (see Table) to the torch
and tighten nozzle retaining nut firmly.
Never touch the nozzle to the work piece.

GENERAL NOTE:
1. 1/2" (12.7 mm) hose is recommended for oxygen, 3/8" (9.5 mm) hose is recommended for fuel gas.
2. Oxygen pressure is measured at the torch inlet connection.
3. The conditions listed in the table are based on typical conditions for cutting mild steel at ambient temperatures.
They should only be used as a starting point. Cut quality can vary depending on the temperature and metallurgical
content of the steel, steel quality, surface condition, oxygen purity, etc., in addition to the pressures and cutting
speed.
4. The post mix nozzles have divergent bore cutting orifices that are intended for applications where it is necessary
to cut quickly. For other specific applications, contact your ESAB representative or distributor.

maximum force. If this does not eliminate leakage, try a
new valve assembly. If then the valve does not shut off
completely, send the torch to a repair station for reseating
of the body.
Cutting Oxygen Valve
If leakage develops around the oxygen valve stem, re-
place the valve packing bushing. If leakage develops
through the oxygen valve, replace the valve seat. Re-
placement procedure as follows:
1. Unscrew the lever attaching screw and lift the lever
off.
2. Unscrew the valve stem guide and remove the valve
assembly from the guide.
3. Use Leak Test Solution to moisten the stem head,
then remove the packing bushing and ferrule. Re-
move the sealing ring from the bushing. Lift off the
spring and spring support.
4. Replace the valve seat (stem) if necessary and any
other parts which are worn or damaged.
5. Reassemble the valve following the above instruc-
tions in reverse order.
Cleaning Cutting Nozzle: If the cutting nozzle does not
produce straight, uniform flames, or if any of the pre-
heat nozzle holes become clogged, clean them by us-
ing the serrated tip cleaners in the cleaning kit supplied
with the torch, part number 751F00. Maintaining clean
preheat holes is essential for quality performance of this
equipment.
If the cutting orifice becomes clogged or fouled, gently
insert and twist the appropriate tapered cleaning tool
found in the cleaning kit. Nozzle P/N 2118703 should
only be cleaned with Oxweld nozzle cleaning compound
P/N 761F00. The use of twist drills for cleaning holes is
not recommended. Nozzles should be cleaned periodi-
cally in a solution of OXWELD Nozzle Cleaning Com-
pound (P/N 761F00), made up and used as directed on
the container in which it is packed.
MAINTENANCE
For all repairs other than those covered below, send the
torch to ESAB Welding & Cutting Products
Remanfacturing Center, 411 South Ebenezer Road, Flo-
rence, SC 29501.
Testing Seats: Under normal use the internal seating
surfaces in the nozzle socket should last the life of the
torch. Should reseating be necessary, reseating should
be done only by the factory or a qualified repair person.
To test the seat, thinly coat the seating surfaces of a
new nozzle with nondrying Prussian blueing. Insert the
nozzle into the nozzle socket without the nozzle nut and
rotate the nozzle by hand one half turn. Remove the
nozzle and observe the seating surfaces in the socket.
Blueing should be evenly distributed on both seating
surfaces. Depressions or the absence of uniform blue-
ing indicates the nozzle socket requires reseating.
Reseating: By hand, screw in reseating tool P/N
5230207 into nozzle head. Do not overtighten or dam-
age to head could result. While gently tightening and
holding threaded nut of reseating tool, slowly rotate
reamer allowing tapered seat to be reseated. Make sure
reamer is rotated at least two revolutions so that reseated
surfaces are true. Retest seats and repeat if necessary
until seating surfaces have been restored. Clean out
metal shavings before putting torch back into service.
PM nozzles cannot and should not be reseated.
Preheat Valves: Leakage around either throttle valve
can usually be corrected by tightening the packing nut
slightly. If this does not stop the leakage, replace the
throttle valve.
If either preheat valve fails to shut off completely, re-
move the throttle valve assembly from the torch. With a
clean cloth, wipe the ball in the end of the stem. Then
reinsert valve assembly and tighten it several times with
