C-57-R CUTTING TORCH
OPERATION 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 nuts with a wrench.
3. Attach nozzle to torch head, and tighten connection nut
with a wrench.
4. Check valve packing nuts for tightness.
ADJUSTING GAS PRESSURES
Low-Pressure Fuel Gas: Be sure the torch fuel gas valve is
closed. Open the supply valve.
Medium-Pressure 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 screw on the
oxygen regulator until its delivery-pressure gauge registers
the desired pressure (see cutting chart on page 6). 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 regulator caps.
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 are closed. Then turn in the regulator pressure-
adjusting screws until the oxygen delivery-pressure gauge
registers 60 psi and the fuel gas 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-hose connections,
and the hose-to-torch 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 the leakage at all torch valves and at
the nozzle nut.

SAFETY PRECAUTIONS
4
LIGHTING AND FLAME ADJUSTMENT
1. Open the preheat oxygen valve on the torch about two
turns.
2. Open the fuel gas valve on the torch about 1/8 turn
(about two turns if using low pressure fuel gas) and light
the gas at the nozzle with a friction lighter. DO NOT USE
A MATCH. Use of a match could seriously burn your
hand.
3. If using acetylene, open the fuel gas valve until preheat
ames leave the end of the nozzle and then close just
enough to open cutting oxygen valve and then readjust
the preheat ames to the shortest length by opening the
preheat oxygen valve gradually.
The above procedure usually provides adequate preheat
for 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.
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 released from the torch, hoses, and
regulators do 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 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 exceptional 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 cut-
ting nozzles or welding tips are cleaned frequently; and (3)
operating pressures are correct. Should a ashback occur,
IMMEDIATELY shut o the torch. Allow it to cool o for a
least a minute. Then check your nozzle or tip, gas pressures,
readjust regulators if necessary, and relight the torch. If
ashback recurs, send the cutting torch with nozzle to your
distributor for repair.
MAINTENANCE INSTRUCTIONS
For all repairs other than those covered below, send the ap-
paratus to your welding equipment distributor. Improperly
repaired apparatus is hazardous. Parts shown in the illustra-
tion on page 3 that require brazing operation are provided
for experienced and qualied persons engaged in the repair
of this apparatus.
Preheat Valves: Leakage around either valve stem can usu-
ally be corrected by tightening the packing nut slightly.
If either preheat valve fails to shut o completely, remove
the valve stem assembly from the torch. With a clean
cloth, wipe the ball in the end of the stem. Then reinsert
valve stem 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 valve stem assembly, tighten the pack-
ing nut until the valve stem 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 stem turns readily.
Cutting Valve Leakage: If leakage develops in the cutting
valve, replace cutting valve seat (32Z01).
To Replace Cutting Valve Seat
1. Remove (4) four screws (61608849) from the handle
(4689) and slide the handle forward as far as possible.
Remove the thumb piece (3634) from the lever (923640)
and the pusher pin (923634) from the pusher rod guide
(923635).
2. Mark the location of the pusher rod guide on the cut-
ting oxygen tube (923633). Loosen the two set screws
(6133-0907) on the pusher rod guide and slide the guide
forward as far as possible.
3. Using a spanner wrench (5190125) remove the cutting
valve assembly by unscrewing the lockscrew (57K02).
Replace both 0-rings (85W11) and (14K07) and the seat
(32Z01).
4. Replace the cutting valve assembly back in the torch and
tighten the lockscrew with the spanner wrench.
5. Locate the pusher rod guide on the markers made previ-
ously, tighten the two set screws and replace the pusher
pin in the guide.
6. Slide the handle back and replace the thumb piece on
the lever. Locate the handle over the four screw holes
and replace the screws.

Cleaning the Injector:
1. Remove the mixing chamber plug (35Z60) and the injec-
tor locking screw (35Z59) from the mixer body (21Z74).
2. If gentle tapping of the mixer body does not cause the
injector to fall out, screw a No. 10-32 machine screw into
the end of the injector and pull it out.
3. Clean the recess in the mixer body with a clean cloth.
4. Clean the injector orice with a No. 70 drill, wipe with a
clean cloth.
5. Examine the injector carefully. If it is nicked or marred,
on the seating surface, replace it with a new injector.
6. Insert the injector into the mixer body, and lock it se-
curely in place with locking ring.
7. Replace O-ring if necessary, and then install the mixer
chamber plug. Tighten plug rmly with a screwdriver.
Cleaning Cutting Nozzles: If the cutting nozzle does not pro-
duce straight, uniform ames, or if any of the nozzle orices
become clogged, clean them by hand with the correct size
twist drills shown in the table on page 4, or with ESAB tip
cleaners. (The relationship between ESAB tip cleaners and
drill sizes is shown on the tip cleaner case.)

OPERATING DATA, CLEANING DATA, AND PART NUMBERS
GENERAL NOTES:
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 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 cut-
ting operations.
2. The tables shown average values based on typical condi-
tions. The type and quality of steel, its surface condition,
the purity of oxygen, etc. will always have a bearing on
the end results.
NOTE: If using the C-57-R for fuel gases other than acetylene, see your ESAB representative.
