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.
F-9969-H
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.
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
F-9969-H
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, always stand to one side of the regulator, not in front
of the gauge face.
TESTING FOR LEAKS:
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 working pressure by turning the pressure-adjusting screw
(clockwise to increase pressure; counterclockwise to
decrease). Close the torch or appliance valve immediately after resetting the regulator.
STOPPING WORK:
Turn the pressure-adjusting screw on the regulator to
the right (clockwise) until the delivery-pressure gauge
Be sure this information reaches the operator.
You can get extra copies through your supplier.
1. Whenever you stop work, and intend to leave the
outfit unattended, always close the tank valve. It
is not necessary to disturb the setting of the regulator 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 automobile trunk.
3. NEVER solder a container that contains or has
contained flammable liquids or vapors (including
gasoline, benzene, solvents, and similar materials) unless the container has been thoroughly
purged of all traces of flammable material and vapors.
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.
1 1. 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 fusible metal safety devices. NEVER store tanks near
radiators, furnaces, or other heat sources.
