These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe

practices for oxy-fuel gas equipment, we urge you to read our booklet “Precautions and Safe Practices for Gas Welding,

Cutting and Heating, Form 2035. Do NOT permit untrained persons to install, operate, or maintain this equipment. Do NOT

attempt to install or operate this equipment until you have read and fully understand these instruction. If you do not fully

understand these instructions, contact your supplier for further information.

The torches covered by these instructions are made to exact specifications. It must be used only in combination of cutting

nozzles and parts manufactured by ESAB Welding & Cutting Products, and used in gas service for which it is designed.

The use of other cutting nozzle and parts that cause damage or failure to the equipment will void the manufacturer's warranty.

Do NOT use torch with acetylene. Using acetylene can

overheat and burn torch which can cause injury to

personnel in the operation area.

The PM-100, PM-200, and PM-300 Machine Cutting Torches

are post mixed design permitting the oxygen and fuel gas to

be mixed externally at the exit end of the torch. No internal

mixing of the gases 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 permitting

high standoff of torch to workpiece; thus increasing the life of

the torch and nozzle.

The PM-100, PM-200, and PM-300 were designed for auto-

matic cut-off operations, such as hot and cold slab cut-off,

slitting, and end cropping. Contour (shape) cutting can also

be done provided edge starts are used to initialize the cuts.

The PM-100 has a 1-3/8” (35 mm) diameter barrel suitable

for standard torch holders. The PM-200 and PM-300 have 2"

(51 mm) barrels which are suited to larger torch holders as

found on most heavy duty cutting machines.

OPERATING INSTRUCTIONS

EQUIPMENT REQUIRED (See Fig. 1)

1. Hoses – On the PM-100 Torch , use 3/8-in. (9.5 mm) I.D.

hose for cutting oxygen, preheat oxygen, and fuel gas

with proper “B” – size fittings (9/16” – 18 right hand

threads for oxygen; 9/16 – 18 left hand threads for fuel

gas).

(On the PM-200, use ½-in. (12.7 mm) cutting oxygen hose

with “C” – size fitting, on the PM-300, use ¾-in. (19 mm)

cutting oxygen hose with “D” - size fitting.)

2. Regulation Panels – OXWELD Regulation Panels are

OSHA Approved and are for station regulation of the

preheat gases and cutting oxygen. They include all valves,

safety devices, and oxygen filter for reliable long service

life. The panels are mounted to a frame which can be

easily mounted to a wall or column. OXWELD Regulation

panel P/N 2116395 recommended. Be sure to read and

understand all instructions packed with each regulation

panel before installing or operating.

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 improp-

erly 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

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 supply and open the torch valve to remove

pressure from the system. Break the leaky connection, wipe

metal seating surface 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 around hose connections at each

valve and torch fitting and at the nozzle nut.

LlGHTlNG AND FLAME ADJUSTMENT

Open each valve and light the gas at about 3 inches from the

nozzle face with a friction lighter. Do NOT use a match. Use of

a match can seriously burn your hand.

Adjust pressure at the regulator if necessary. The torch is

designed to operate over a wide range of preheat pressures.

The pressures given in the Table may be used as a starting

point. Depending on the type steel being cut, small adjust-

ments may be necessary for best performance.

SHUTTING OFF

Close the cutting oxygen valve. Then close the preheat

oxygen and fuel gas valves.

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

pressure should be released from all regulators as follows:

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

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.

Burnback: Under certain exceptional circumstances, the

flame may not “pop” out (backfire) but instead burn back at the

torch nozzle and head. A burnback should never occur if the

nozzle is tight and equipment is in good condition. Should a

burnback occur, IMMEDIATELY shut off the torch. Allow it to

cool off for at least a minute. Remove torch from holder and

visually inspect for damaged or galled threads, nicks on

nozzle or seat. If damaged, replace the torch. If no damage is

evident, replace nozzle and tighten and relight. If burnback

recurs, send the torch along with the nozzle in use only to

ESAB Remanufacturing Center, Ebenezer Road, Florence,

SC 29501.

Note: For hot cutting applications - Regulation

panels do not include the capability for con-

trolling the cooling water/air – these must be

supplied by customer.

If a regulation panel is not used, refer to Fig. 1 for proper

placement of regulation equipment.

3. Valves – These torches are valveless. Control of the

gases should be done by adjusting the regulators on the

regulation panel. If a regulation panel is not used, suit-

able ball valves or remotely operated solenoid valves,

and regulators should be installed for on-off torch control.

4. Pipeline Filters – Regulation panel P/N 2116395 in-

cludes an oxygen filter. If a regulation panel is not used

but filters are desired, use P/N 2116734 for oxygen and

P/N 2116339 for fuel gas. Filters should be installed

ahead of the inlet connection of each regulator.

5. Adaptors/Piping - 3/4-in (19mm) piping is recommended

from each gas source to the regulators. Various commer-

cially available adaptors will be required for the system.

Be sure that all piping and adaptors are free of grease and

oil. Grease, oil, and similar combustible materials once

ignited burn violently in the presence of oxygen. Teflon

tape or paste or an approved pipe compound must be

used on all pipe threads.

6. Cutting Nozzles - Select desired nozzle from Cutting

Data table.

OPTIONAL ACCESSORIES

1. Air/Water Cooling – The torches are equipped with two

air/water fittings (5/8”-18 RH male). Air at 10 psi (0.4 bars)

or water is recommended for torch cooling when torch is

used for hot cutting operations.

2. Gauge Adaptors – The following gauge adaptors are

recommended for setting the gas flows (see Table).

Gauge adaptors connect to the inlet connections but

should be removed when cutting over hot material.

CONNECTING

1. Before connecting, make sure all metal seating surfaces of

hoses, torch, and regulators are not damaged and clean

free of grease and oil.

2. Connect hoses (2 oxygen; 1 fuel gas) to the proper fitting on

the torch and to the manual or solenoid shutoff valves

downstream of the regulator. Tighten the connecting nuts

firmly using two wrenches to prevent twisting of tubes

inside the torch.

3. Assemble desired nozzle (see Table) to the torch and

tighten nozzle retaining nut firmly with two 1-1/8 (29mm)

open-end wrenches.

ADJUSTING GAS PRESSURES

1. Open the cutting oxygen line manual or solenoid shutoff

valve. Adjust cutting oxygen regulator to the desired pres-

sure (see Table) compensating for any line loss to the torch

through the hose and valve. Then immediately close the

cutting oxygen shutoff valve.

2. Repeat above with the preheat oxygen, and then with the

fuel gas.

OPERATING DATA

GENERAL NOTE:

1. All gas pressures measured at the torch inlet connections with gasses flowing.

2. The pressures and cutting speeds 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. Hot steel (1400ºF/760ºC) cutting speeds will be approximately

30% - 50% faster. Cut quality can vary depending on the temperature and metallurgical content of the steel, casting speed,

cut-off machine, steel quality, surface condition, oxygen purity, etc., in addition to the pressures and cutting speed.

3. The cutting orifices of divergent bore nozzles should be carefully cleaned in order not to damage the cutting bore.

* Non-Divergent Bore: (See Cleaning Cutting Nozzles)

Cleaning Cutting Nozzle:

Preheat Holes: If the cutting nozzle does not produce straight,

uniform flames, or if any of the preheat holes become clogged,

clean them by using one of the serrated tip cleaners in the PM-

100/200/300 Cleaning Kit, Part No. 751F00. Maintaining clean

preheat holes is essential for quality performance of the torch.

Divergent Cutting Bore Nozzles: If the divergent cutting

orifice becomes clogged or fouled, gently insert and twist the

appropriate tapered cleaning tool found in the cleaning kit.

Larger size cutting orifices should be cleaned by inserting the

sharpened, tapered end of a common wooden pencil and

gently rotating until the fouling is removed. The use of twist

drills for cleaning holes is not recommended and may ruin the

nozzle. Nozzles should be cleaned periodically in a solution of

OXWELD Nozzle Cleaning Compound (P/N 761F00), made

up and used as directed on the container in which it is packed.

Non-Divergent Bore Nozzles: Clean the cutting bore by

inserting the sharpened, tapered end of a common wooden

pencil and gently rotating until the fouling is removed.

MAINTENANCE

For all repairs, send the torch to ESAB Welding & Cutting

Products Remanufacturing Center, 411 South Ebenezer Road,

Florence, SC 29501.

Testing Seats: When the torches are water cooled, the

internal seating surfaces in the nozzle socket should last the

life of the torch. Air cooling or no cooling especially in hot

cutting operations, will shorten the life of the torch and the

seating surfaces. 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 blueing

indicates the nozzle socket requires reseating.

PM nozzles cannot and should not be reseated.
