ESAB PREST-O-LITE® R-416 Fuel Gas Regulators Troubleshooting instruction

Brand: ESAB

Model: PREST-O-LITE® R-416 Fuel Gas Regulators

Type: Troubleshooting instruction

ESAB PREST-O-LITE® R-416 Fuel Gas Regulators are designed for use with FG-2, propane, and MAPP gases. They have a CGA-510 inlet connection and a CGA-021 (3/8"- 24 LH) outlet connection. The delivery pressure range is 0-60 psig, and the flow capacity is 0-130 cfh. The regulators are equipped with a 1-1/2-in. diameter delivery pressure gauge with a range of 0-100 psig.

The R-416 regulators are ideal for use with oxy-fuel gas equipment, such as torches and cutting equipment. They are also suitable for use with other applications that require a regulated supply of fuel gas.

Here are some of the features and benefits of the ESAB PREST-O-LITE® R-416 Fuel Gas Regulators:

These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe

practices for oxy-fuel gas equipment, we urge you to read our booklet "Precautions and Safe Practices for Welding, Cutting,

and Heating," Form 2035. Do NOT permit untrained persons to operate this equipment. Do NOT attempt to 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 used in combination with

parts manufactured by ESAB Welding & Cutting Products to the specifications on file with Underwriter's Laboratories, Inc.,

and when they are used in the gas service for which they are designed and listed. The use of other parts that cause damage

or failure to the equipment will void the manufacturer's warranty.

shows at least 60 psi pressure. Using a thick solution

of soap and water, applied with a small brush, test for

leaks at the tank valve, regulator connections, and torch

or appliance connection. If you find a leak, correct it

before continuing. (A leak around the stem of a fuel

gas tank valve can often be corrected by tightening

the valve packing nut with a wrench. If this will not

stop the leak, remove the tank, tag it to indicate valve

stem leakage, and place it outdoors in a safe spot until

you can return it to your supplier.)

SETTING WORKING PRESSURE:

Open the torch or appliance valve and then quickly

reset the regulator to deliver gas at the desired work-

ing pressure by turning the pressure-adjusting screw

(clockwise to increase pressure; counterclockwise to

decrease). Close the torch or appliance valve immedi-

ately after resetting the regulator.

STOPPING WORK:

1. Whenever you stop work, and intend to leave the

outfit unattended, always close the tank valve. It

CONNECTING:

1. Before attaching the regulator to a tank (cylinder)

open the tank valve slightly, for an instant, then

close it. This will blow out any dust or dirt which

may be in the valve outlet. Never open the tank

valve near hot work, a spark-creating device,

or any other possible source of ignition.

2. Attach the regulator to the tank valve. Tighten the

connection nut with a wrench.

3. Attach hose with correct fittings to the regulator

outlet and to the torch or other appliance. (All fuel

gas hose connection nuts have left-hand threads.)

Tighten the connection nuts with a wrench.

4. Make sure the shutoff valve on your torch or other

appliance is closed. Then open the tank valve about

one-quarter turn. When opening the tank valve, al-

ways stand to one side of the regulator, not in front

of the gauge face.

TESTING FOR LEAKS:

Turn the pressure-adjusting screw on the regulator to

the right (clockwise) until the delivery-pressure gauge

SPECIFICATIONS

4. Before starting work always test for leaks around

all joints with a soapy water solution.

5. NEVER use a flame to test for leaks of flammable

gases.

6. NEVER use a tank with a leaking valve.

7. DON'T attempt any repairs to an LFG tank, except

to tighten the packing-gland nut on the valve.

8. DON'T abuse or drop tanks or handle them roughly.

9. NEVER use a tank as a roller or support.

10. NEVER use a hammer, wrench, or pliers on an

LFG tank valve which is fitted with a handwheel.

11. NEVER allow full tank pressure to enter the hose.

Always use a regulator when there is a needle valve

on the torch handle.

12. NEVER lay a torch down unless the gas flow has

been shut off. If you want to maintain a pilot flame

when you stop work for short intervals, provide a

rack or stand for the torch, away from combustible

materials. Do not leave it unattended unless you

are sure there is no danger of its being disturbed

by unauthorized persons.

13. Examine your hose for leaks frequently. Dipping it

in a bucket of clean water, with the pressure in the

hose, is the quickest and easiest way.

14. DON'T use hose that is worn, or any equipment

that is in need of repairs.

15. DON'T start fires. BE very careful when working

near combustible material.

16. Fuel gas tanks (cylinders) are equipped with fus-

ible metal safety devices. NEVER store tanks near

radiators, furnaces, or other heat sources.

is not necessary to disturb the setting of the regu-

lator pressure-adjusting screw.

2. When the regulator is removed from the tank, and

is to be idle for some time, leave the adjusting screw

turned in to keep the regulator valve seat off the

seating surface within the regulator.

REPAIRING:

Regulators in need of repair should be returned to

your ESAB equipment supplier.

If you have your own properly-equipped and staffed

repair facility, repair parts information for this regulator

is available on request to your distributor. Request

Form 12-384 which covers all regulators listed on this

sheet.

SAFETY PRECAUTIONS

1. DON'T let liquefied fuel gas (LFG) escape near

any possible source of ignition. Accumulations of

gas in certain proportions may explode if ignited.

2. NEVER store LFG tanks (cylinders) in a closed or

confined space, such as a closet, tool box, or au-

tomobile trunk.

3. NEVER solder a container that contains or has

contained flammable liquids or vapors (including

gasoline, benzene, solvents, and similar materi-

als) unless the container has been thoroughly

purged of all traces of flammable material and va-

pors.
