C-58 MACHINE CUTTING TORCHES

OPERATING INSTRUCTIONS

CONNECTING

1. Attach regulators to the oxygen and fuel gas cylinders. Fol-

low all instructions supplied with the regulators.

NOTE: If using the 3-hose C-58 torch, use two oxygen

cylinders-one for cutting oxygen and the other for

preheat oxygen.

2. Attach the oxygen and the fuel gas hoses to the regulators

and to the proper connections on the torch, after making

sure all metal seating surfaces are clean. Tighten all con-

nection 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.

Flashbacks can cause serious burns.

Be sure gas ow is sufcient 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.

ADJUSTING GAS PRESSURES

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). Then immediately close the fuel gas valve.

SPECIFICATIONS

Cutting Capacity using acetylene ...........................6-in. (150 mm)

Cutting Capacity using other fuel gases ...................2-in. (50 mm)

Cutting Nozzles ............................................................1500 series

Torch-Hose Connections .................................."B" size (9/16"-18)

Overall Length .................................................12-1/2in. (318 mm)

Barrel Diameter ...................................................1-3/8-in. (35 mm)

Be sure this information reaches the operator.

You can get extra copies through your supplier.

Oxygen: Open the cutting oxygen valve wide and turn in the

pressure-adjusting screw on the oxygen regulator until its

delivery-pressure gauge registers the desired cutting oxygen

pressure (see cutting chart). Then close the cutting oxygen

valve.

If using the 3-hose C-58 torch, open the preheat oxygen

valve two full turns and adjust regulator to the desired preheat

oxygen pressure (see cutting chart). Then close the preheat

oxygen valve.

NOTE: When gaugeless regulators are used, do not open

torch valves. Merely turn in the pressure-adjusting

screws to the desired pressure as indicated on the

scales of the regulator caps.

TESTING FOR LEAKS

Every cutting outt 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 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-regulator connections,

the regulator-to-hose connections, and the hose-to-torch con-

nections. 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 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 satised that all connections

are gas-tight.

After lighting the torch and adjusting ames, use leak test

solution to check for leakage at all torch valves and at the

nozzle nut.

SAFETY PRECAUTIONS

Backre: Improper operation of the torch may cause the

ames to go out with a loud 'pop'. Such a backre may be

caused by contact 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 (backre) 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 ash-

back occur, IMMEDIATELY shut off the torch. Allow it to cool

off 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

torch to your ESAB welding equipment distributor or to ESAB

Remanufacturing Center, Florence, SC. Improperly repaired

apparatus is hazardous.

Valves: Leakage around a throttle valve can usually be cor-

rected by tightening the packing nut slightly. If a valve fails

to shut off completely, remove the 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 maximum force. If this does not eliminate leakage, try a

new throttle valve assembly. If then the valve does not shut

off completely, send the torch to a repair station for reseating

of the body.

After installing a new throttle valve assembly, tighten the pack-

ing nut until the valve can be turned only with great difculty,

and set the unit aside, for three or four hours at least, to set

the packing. Then back off the packing nut until the valve

turns readily.

Mixer: To remove the mixer for cleaning or replacement, rst

unscrew the mixer chamber plug. Then unscrew the mixer

locking screw. Finally, dislodge the mixer either by rapping

the torch, held vertically, against a block of soft wood, or by

turning a long 10-32 machine screw into the thread in the end

of the mixer and pulling it out.

Reassemble the mixer in reverse order. Be sure the mixer

chamber plug is tted with an O-ring in good condition.

Cleaning Cutting Nozzles: If the cutting nozzle does not pro-

duce straight, uniform ames, or if any of the nozzle orices

become clogged, clean them by hand with the correct size twist

drills shown in the table on page 4, or with tip cleaners. (The

relationship between OXWELD tip cleaners and drill sizes is

shown on the tip cleaner case.)

NOTE: If using a 1563 series nozzle, do NOT clean with

notched-type wires or twist drills since any metal

removal from the passages will destroy the precision

cutting characteristics. Use the non-cutting wires

and taper reamers included in the OXWELD Nozzle

Cleaning Kit (P/N 755F00). Cleaning instructions are

supplied with the kit.

LIGHTING AND FLAME ADJUSTMENT

CAUTION: Use friction lighter for lighting torch. Do NOT use

a match. Use of a match can seriously burn you

hand.

Using Acetylene

1. Open the acetylene valve on the torch about 1/2 turn, and

light the gas at the nozzle.

2. Slowly close the acetylene valve until the yellow ame just

starts to throw off black smoke.

3. Slowly open preheat oxygen valve on torch until neutral

ames are obtained.

4. Finally, open the cutting oxygen valve and readjust for

neutral ames by turning preheat oxygen valve.

The ame now has the proper strength for any cutting job.

With this ame, acetylene is being consumed economically

and the torch will be operating at best resistance to ashback.

If greater preheat ame temperature is desired for faster starts

or piercing, open the cutting oxygen valve and adjust the pre-

heat oxygen valve until the ame inner cones shorten about

10 percent and become sharply pointed.

Using Fuel Gases except Acetylene

1. Crack the fuel gas valve and light the gas at the nozzle.

2. Open fuel gas valve until ame starts to leave the end of

the nozzle.

3. Slowly open preheat oxygen valve on torch until ame

stabilizes.

4. Open cutting oxygen valve and then adjust preheat oxygen

valve until preheat ames are at their shortest length.

5. If larger or smaller preheat ames are desired, alternately

readjust fuel gas and preheat oxygen valve to obtain the

nal ame setting.

SHUTTING OFF

Close the cutting oxygen valve. Then close the fuel gas valve,

and nally the preheat oxygen valve.

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

sure 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

Flow: There must be proper ow of gases for safe operation

and full performance. This requires the following three condi-

tions: (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.

OPERATING DATA, CLEANING DATA, and PART NUMBERS

GENERAL NOTES:

1. 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.

2. The table 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.
