OPERATING INSTRUCTIONS for

F15-330

June, 2006

z Prevent leaks.

z Do not change CGA inlet connection from number

stamped on regulator body.

z Follow operating instructions on this sheet.

z This regulator must be installed, operated and

maintained only by trained servicemen.

z For complete safety information on welding and

cutting equipment, read Form 2035 (oxy-fuel gas)

and 52-529 (arc welding). For safety information

on gases, see your supplier.

INSTALLATION & OPERATION

TO CONNECT:

1. Open the cylinder valve slightly, for an instant, to

blow out any dust or dirt that may have collected in

the valve outlet. BE SURE to keep your face away

from the valve outlet to protect your eyes.

2. Attach the regulator to the cylinder valve. Align

the regulator so that the flowmeter is vertical and

then tighten the connection nut with a wrench. (Do

NOT use the flowmeter tube as a "handle" when

attaching the regulator.

3. Make sure that the flow control valve on the flow-

meter is closed.

4. Open the cylinder valve SLOWLY.

5. Attach hose to the flowmeter outlet and to the equip-

ment with which the gas is to be used. Tighten the

connecting nuts with a wrench.

DESCRIPTION

The R-72-FM-580 is a small, compact regulator/flow-

meter combination calibrated for use with argon, he-

lium, nitrogen, and C-25 (75% argon - 25% carbon diox-

ide). It is equipped with a CGA 580 inlet connection

and a standard "B" inert gas connection (5/8—18 RH

female). The scales marked on the square plastic tube

are calibrated in cubic feet per hour (CFH). This tube

can be rotated by hand so that any scale can be read

from a convenient position. The range of each cali-

brated scale is as follows:

Argon - 10 to 70 CFH (4.7 to 33 L/min)

Helium - 20 to 220 CFH (9.4 to 103 L/min)

Nitrogen - 10 to 80 CFH (4.7 to 38 L/min)

C-25 - 10 to 65 CFH (4.7 to 31 L/min)

To convert to liters per minute (L/min) multiply the scale

reading by 0.47.

For gas mixtures other than C-25, consult your gas

supplier for the conversion factor that will apply to one

of the calibrated scales.

INERT GAS OR CARBON DIOXIDE can cause suf-

focation in confined spaces.

z Always work in well ventilated area.

The INSTRUCTIONS contained in this booklet are intended specifically for operators who know the general principles of operation and safe

practices to be followed in operating this type of equipment. If you are not sure that you understand these principles fully, we urge you to

read our booklet "Precautions and Safe Practices for Arc Welding, Cutting and Gouging", Form 52-529, in addition to these instructions. 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 instructions. If you do not fully understand these instructions, contact your supplier for further

information.

The regulator-flowmeter covered by these Instructions is listed by Underwriter's Laboratories only when using parts manufactured by ESAB

Welding & Cutting Products to the specifications on file with Underwriter's Laboratories, Inc. and when used in the gas service for which it

is designed and listed. The use of other parts voids the manufacturer's warranty.

Be sure this information reaches the operator.

TO REGULATE FLOW:

Flow is controlled by adjusting the flowmeter valve until

the desired flow is indicated by the ball float in the flow-

meter tube. Always take the reading across the TOP

of the ball.

IMPORTANT: Before starting operations, test all con-

nections with a suitable Leak Test So-

lution, such as P/N 998771 (8 oz. con-

tainer). Correct any leaks before start-

ing work. Testing should be performed

after torch or a gas - using device has

been properly connected.

TO STOP WORK:

When work is to be stopped for a half-hour or more, or

when the regulator is to be disconnected from the cyl-

inder, proceed as follows:

1. Close the cylinder valve.

2. Open flowmeter valve and all valves downstream

to release trapped gas in regulator and hose.

3. When pressure gauge on regulator drops to zero,

close flowmeter valve.

INLET FILTER MAINTENANCE:

Each regulator is equipped with a porous metal inlet

filter, P/N 71Z33, pressed into the regulator inlet nipple.

No regulator should be connected to a cylinder or sta-

tion valve unless it contains this filter. You can replace

the filter if you have reason to do so. To remove a

filter, insert a No. 1 'EZY-OUT' or a No. 6 wood screw

(about 2-in. long) into the filter and pull it out. Press

the new filter into the nipple with a 1/4-on. round metal

rod.

REPAIR SERVICE:

Regulators in need of repair should be returned to your

distributor or to ESAB Remanufacturing Center, 411

S. Ebenezer Road, Florence, S C 29501.

NOTE: Safety release device equipped on this regula-

tor-flowmeter is designed for regulator protec-

tion: not for hose or equipment downstream. If

gas escapes through the vent hoses of the cap,

immediately close cylinder valve, and then re-

move regulator-flowmeter from the service for

repair.
