Brand: ESAB

Model: R-27-CF-580 Series "B" Argon Regulator

Type: User manual

ESAB R-27-CF-580 Series "B" Argon Regulator is a versatile and reliable regulator designed for use with argon gas cylinders. It features a CGA-580 inlet connection and a CGA-032 outlet connection, making it compatible with a wide range of welding and cutting equipment. The regulator provides precise flow control with a flow range of 10 to 40 cfh (5-19 L/min), making it suitable for a variety of applications, including welding, cutting, and gouging. The regulator is equipped with two 2-in.

The INSTRUCTIONS contained in this booklet are intended specifically for operators who know the general principles of opera-

tion 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.

* Formally "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 suf-

focation in confined spaces.

l Always work in well ventilated area.

l Prevent leaks.

l Do not change CGA inlet connection from number

stamped on regulator body.

l Follow operating instructions on this sheet.

l This regulator must be installed, operated, and main-

tained only by trained servicemen.

l 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.

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

your face away from the valve outlet to protect your

eyes.

2. Make sure the regulator flow-adjusting screw is

released 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 open-

ing 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.)

Be sure this information reaches the operator.

You can get extra copies through your supplier.

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.

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

oz. container), test the following for leakage: ar-

gon 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 decrease delivery flow, turn

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

NOTE: When using the R-27-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 weld-

ing or when adjusting argon flows at the regu-

lator 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 (8 oz. container). Cor-

rect any leaks before starting work.

Testing should be performed after torch

or other gas-using device has been

properly 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 the 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 com-

pletely 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

ESAB Welding Equipment distributor or the ESAB

Remanufacturing Center, 411 S. Ebenezer Road, Flo-

rence, SC 29501.

If you have your own properly equipped and staffed

repair facility, repair parts information for this regulator

(Form F-15-300) is available on request.

NOTE: Safety release device equipped on this regu-

lator is designed for regulator protection, not

for hose or equipment downstream. If gas

escapes through the vent holes in the cap,

immediately close cylinder valve and then re-

move regulator-flowmeter for repair.
