ESAB R-72-CF-580 Series "B" Argon Regulator User manual

Brand: ESAB

Model: R-72-CF-580 Series "B" Argon Regulator

Type: User manual

ESAB R-72-CF-580 Series "B" Argon Regulator is a device designed to control the flow of argon gas in welding and cutting applications. It is equipped with a CGA-580 inlet connection for attachment to an argon cylinder and a CGA-032 outlet connection for attachment to a welding torch or other gas-using device. The regulator features a flow range of 10 to 40 cfh (5-19 L/min), making it suitable for a wide range of applications. It also has two 2-inch diameter gauges, one for indicating cylinder pressure and the other for indicating delivery flow.

R-72-CF-580

SERIES "B" ARGON REGULATOR

PART NO. 0558005417

The INSTRUCTIONS contained on this sheet 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 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.

SPECIFICATIONS

TO CONNECT

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

then close it. This is known as "cracking" the valve.

This blows away any dirt or dust which may have

accumulated in the valve outlet. Be sure to keep

you face away from the valve outlet to protect your

eyes.

2. Make sure the regulator flow-adjusting screw is re-

leased by turning it to the left (counterclockwise)

until it turns freely.

3. Attach the regulator to the cylinder valve, and tighten

the union nut securely with a wrench.

4. Open the cylinder valve slowly a fraction of a turn.

When the cylinder pressure gauge pointer stops

moving, open the valve fully. Never stand directly

in front of or behind the regulator when opening the

cylinder valve. Always stand to one side.

5. Attach the torch hose to the regulator outlet ("B" -

size inert gas female connection) and tighten the

connection snugly with a wrench. (A shutoff valve,

such as the OXWELD V-30 Argon-Water Shutoff

Valve, P/N 16X21, may be connected between the

regulator and torch if desired.)

TO TEST FOR LEAKAGE

1. Close the torch switch or shutoff valve.

2. Turn the flow-adjusting screw to the right (clock-

wise) until about normal working flow is obtained,

as shown on the delivery flow-gauge.

* Formerly "B" size Inert Gas (5/8"—18 RH female)

** Gauge calibrated in cfh with flow through metering spud

installed in outlet connection.

INERT GAS OR CARBON DIOXIDE can cause suffo-

cation in confined spaces.

z Always work in well ventilated area.

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 main-

tained only by trained servicemen.

z For complete safety information on welding and cut-

ting equipment, read form 2035 (oxy-fuel gas) and

52-529 (arc welding). For safety information on gases,

see your supplier.

3. Using Leak Test Solution such as P/N 998771 (8

oz. container), test the following for leakage; argon

cylinder valve stem, regulator inlet connection, and

hose connections at the regulator outlet and torch.

TO ADJUST FLOW

Open the torch switch or shutoff valve whenever you

adjust the torch argon flow to obtain a true reading on

the delivery flow gauge.

To increase the gas flow, turn the flow-adjusting screw

to the right (clockwise). To decease delivery flow, turn

the flow-adjusting screw to the left (counterclockwise).

NOTE: When using the R-72-CF-580 with a torch

equipped with an argon shutoff valve, the valve

should be used only to turn on or shut off the

flow of argon through the torch. When welding

or when adjusting argon flows at the regulator,

the argon shutoff valve should be

wide open.

IMPORTANT: Before starting operations, test all con-

nections with a Leak Test Solution such

as P/N 998771 (8oz. container). Cor-

rect any leaks before starting work.

Testing should be performed after torch

or other gas-using device has been prop-

erly connected with valve(s) down-

stream of regulator closed, and with

maximum delivery pressure (see table)

in the delivery line.

TO STOP FLOW

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

regulator is to be removed from the cylinder, shut down

the regulator as follows:

1. Close the cylinder valve.

2. Release gas from the regulator by opening all valves

downstream.

3. Allow flow gauge to read zero, then turn the flow-

adjusting screw counterclockwise until it turns

freely.

NOTE: If regulator is to be out of use for more than a

day, turn in the flow-adjusting screw enough to

move the valve stem off the seat. When the

regulator is returned to service, be sure to back

out the flow-adjusting screw completely before

admitting cylinder pressure to the regulator.

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-in. 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 SC 29501.

NOTE: Safety release device equipped on this regula-

tor is designed for regulator protection; not for

hose or equipment downstream. If gas escapes

through the vent holes of the cap, immediately

close cylinder valve, and then remove regula-

tor from service for repair.
