SECTION 2:

GENERAL SAFETY INFORMATION

Read and understand all safety and operating instructions provided

before using this apparatus. RETAIN THESE INSTRUC TIONS IN A

READILY AVAILABLE LOCATION FOR FUTURE REFERENCE.

2.01 FIRE PREVENTION

Welding and cutting operations use ﬁre or combustion as a basic

tool. The process is very useful when properly controlled. However,

it can be extremely destructive if not performed cor rectly in the

proper environment.

1. The work area must have a ﬁreproof ﬂoor.

2. Work benches or tables used during welding or cutting

operations must have ﬁreproof tops.

3. Use heat resistant shields or other approved material to protect

nearby walls or unprotected ﬂooring from sparks and hot metal.

4. Keep an approved ﬁre extinguisher of the proper size and type

in the work area. Inspect it regularly to ensure that it is in proper

working order. Know how to use the ﬁre extin guisher.

5. Move combustible materials away from the work site. If you

can not move them, protect them with ﬁreproof covers.

WARNING

NEVER perform welding, heating, or cutting operations

on a container that has held toxic, combustible or ﬂammable

liq uids, or vapors. NEVER perform welding, heating, or

cutting operations in an area containing combustible vapors,

ﬂam mable liquids, or explosive dust.

2-4

2.02 HOUSEKEEPING

WARNING

NEVER allow oxygen to contact grease, oil, or other ﬂam-

mable substances. Although oxygen by itself will not burn,

these substances become highly explosive. They can ignite

and burn violently in the presence of oxygen.

Keep ALL apparatus clean and free of grease, oil and other

ﬂammable substances.

2.03 VENTILATION

WARNING

Ade quately ventilate welding, heating, and cutting work

areas to prevent accumulation of explosive or toxic concen-

trations of gases. Certain combinations of metals, coatings,

and gases generate toxic fumes. Use respiratory protection

equipment in these circumstances. When welding/brazing,

read and understand the Material Safety Data Sheet for the

welding/brazing alloy.

2.04 PERSONAL PROTECTION

Gas ﬂames produce infrared radiation which may have a harm ful

effect on the skin and especially on the eyes. Select goggles or a

mask with tempered lenses, shaded 4 or darker, to protect your

eyes from injury and provide good visibility of the work.

Always wear protective gloves and ﬂame-resistant clothing to protect

skin and clothing from sparks and slag. Keep collars, sleeves, and

pockets buttoned. DO NOT roll up sleeves or cuff pants.

When working in a non-welding or cutting environment, always

wear suitable eye protection or face shield.

2-5

WARNING

Practice the following safety and operation precautions

EVERY TIME you use pressure regulation equipment.

Deviation from the following safety and operation

instructions can result in fire, explosion, damage to

equipment, or injury to the operator.

2.05 COMPRESSED GAS CYLINDERS

The Department of Transportation (DOT) approves the design and

manufacture of cylinders that contain gases used for welding or

cutting operations.

1. Place the cylinder (Figure 1) where you will use it. Keep the

cylinder in a vertical position. Secure it to a cart, wall, work bench,

post, etc.

Figure 1: Gas Cylinders

WARNING

Cylinders are highly pressurized. Handle with care. Serious

accidents can result from improper handling or mis use of

compressed gas cylinders DO NOT drop the cylinder, knock

it over, or expose it to excessive heat, ﬂames or sparks.

DO NOT strike it against other cylinders. Contact your gas

supplier or refer to CGA P-1 “Safe Handling of Compressed

Gases in Containers” publication.

3-6

NOTE

CGA P-1 publication is available by writing the Compressed

Gas Association, 4221 Walney Road, 5th Floor, Chantilly,VA

20151-2923

2. Place the valve protection cap on the cylinder whenever mov ing

it, placing it in storage, or not using it. Never drag or roll cylinders

in any way. Use a suitable hand truck to move cylin ders.

3. Store empty cylinders away from full cylinders. Mark them

“EMPTY” and close the cylinder valve.

4. NEVER use compressed gas cylinders without a pressure

reducing regulator attached to the cylinder valve.

5. Inspect the cylinder valve for oil, grease, and damaged parts.

WARNING

DO NOT use the cylinder if you find oil, grease or

damaged parts. Inform your gas supplier of this condition

immediately.

6. Momentarily open and close (called “cracking”) the cylinder valve

to dislodge any dust or dirt that may be present in the valve.

CAUTION

Open the cylinder valve slightly. If you open the valve too

much, the cylinder could tip over. When cracking the cylinder

valve, DO NOT stand directly in front of the cylinder valve.

Always perform cracking in a well ventilated area. If an

acetylene cylinder sprays a mist when cracked, let it stand

for 15 minutes. Then, try to crack the cylinder valve again.

If this problem persists, contact your gas supplier.

WARNING

Use the regulator for the gas and pressure for which it is

designed. NEVER alter a regulator for use with any other gas.

NOTE

Regulators purchased with open 1/8”, 1/4”, 3/8”, or 1/2”

NPT ports must be assembled to their intended system.

3-8

1. Note the maximum inlet pressure stamped on the regulator. DO

NOT attach the regulator to a system that has a higher pressure

than the maximum rated pressure stamped on the regulator.

2. The regulator body will be stamped “IN” or “HP” at the inlet

port. Attach the inlet port to the system supply pressure

connection.

3. Wrap pipe threads with Teﬂon tape 1 1/2 to 2 turns to effect a

seal. If other sealants are used, they must be compatible with

the gas that will be used in the system.

4. If gauges are to be attached to the regulator and the regu lator

is stamped and listed by a third party (i.e. “UL” or “ETL”). The

following requirements must be met:

a) Inlet gauges over 1000 PSIG (6.87 mPa) shall conform with

the requirements of UL 404, “Indicating Pressure Gauges

for Compressed Gas Service.”

b) Low pressure gauges must be UL recognized for the class

of regulator they are being used on according to UL252A.

WARNING

DO NOT use a regulator that delivers pressure exceeding

the pressure rating of the downstream equipment unless

pro visions are made to prevent over-pressurization (i.e.

system relief valve). Make sure the pressure rating of the

down stream equipment is compatible with the maximum

delivery pressure of the regulator.

5. Be sure that the regulator has the correct pressure rating and

gas service for the cylinder used.

6. Carefully inspect the regulator for damaged threads, dirt, dust,

grease, oil, or other ﬂammable substances. Remove dust and

dirt with a clean cloth. Be sure the inlet swivel ﬁlter is clean and

in place. Attach the regulator (Figure 3) to the cylinder valve.

Tighten securely with a wrench.

3-9

WARNING

DO NOT attach or use the regulator if oil, grease, ﬂamma ble

substances or damage is present! Have a qualiﬁed repair

technician clean the regulator or repair any damage.

Figure 3: Regulator to Cylinder Valve

7. Before opening the cylinder valve, turn the regulator adjusting

screw counterclockwise until there is no pressure on the

adjusting spring and the screw turns freely.

8. Relief Valve (where provided): The relief valve is designed to

protect the low pressure side of the regulator from high pres-

sures. Relief valves are not intended to protect down stream

equipment from high pressures.

WARNING

DO NOT tamper with the relief valve or remove it from the

regulator.

WARNING

Stand to the side of the cylinder opposite the regulator when

opening the cylinder valve. Keep the cylinder valve between

you and the regulator. For your safety, NEVER STAND IN

FRONT OF OR BEHIND A REGULATOR WHEN OPENING

THE CYLINDER VALVE!

3.03 LEAK TESTING THE SYSTEM

Leak test the system before putting into operation.

1. Be sure that there is a valve in the downstream equipment to

turn off the gas ﬂow.

2. With the cylinder valve open, adjust the regulator to deliver the

maximum required delivery pressure.

3. Close the cylinder valve.

4. Turn the adjusting screw/knob counterclockwise one turn.

a) If the high-pressure gauge reading drops, there is a leak

in the cylinder valve, inlet ﬁtting, or high-pressure gauge.

b) If the low-pressure gauge drops, there is a leak in the

down stream equipment, hose, hose ﬁtting, outlet ﬁtting or

low-pressure gauge. Check for leaks using an approved

leak detector solution.

c) If the high-pressure gauge drops and the low-pressure

gauge increases at the same time, there is a leak in the

regulator seat.

d) If the regulator requires service or repair, take it to a

qualiﬁed repair technician.

5. Once leak testing has been performed and there are no leaks

in the system, slowly open the cylinder valve and proceed.

WARNING

If a leak has been detected anywhere in the system, dis-

continue use and have the system repaired. DO NOT use

leaking equipment. Do not attempt to repair a leaking

system while the system is under pressure.

4-16

SECTION 4:

WHEN YOU FINISH USING THE REGULATOR

1. Close the cylinder valve.

2. Open the valve on the downstream equipment. This drains all

pressure from the system.

3. Close the valve on the downstream equipment.

4. Turn the adjusting screw counterclockwise to release the ten-

sion on the adjusting spring.

5. Check the gauges after a few minutes for veriﬁcation that the

cylinder valve is closed completely.

4.01 STORAGE

When the regulator is not in use and has been removed from the

cylinder, it should be stored in an area where it will be pro tected

from dust, oil, and grease. The inlet and outlet should be capped

to protect against internal contamination and prevent insects

from nesting.
