Section 2
Start all fitting threads with fingers and turn clockwise until the male fitting begins to seat. Then, use only a wrench to
tighten fittings. Do not use pliers or any type o f gripping device with locking jaws or serrated teeth. When tightening the
tubing fitting to the we lder's CGA 5/8" fitting, use two wrenches, one to hold the machine side fitting and one to turn the
hose side fitting. If two wrenches are not used, the machine side fitting may strip the hole and begin to turn in the hous-
ing and begin to twist the soleno id which the machine mounted fitting is scre wed directly into. Do not overtighten any
fitting. Only use an adjustable wrench if no exact fit wrench is available. Usually 1/8 -1/4 turn after the fitting first begins
to make full contact with the female fitting seat is sufficient for establishing proper tightness. The fittings are brass and
can strip or bre ak if excessive pressure is use d. Do not use sealing tape or pipe thread sealant or any type o f thread com-
pound. Test for leaks with warm soapy water or approved le ak detector at all fittings (including main cylinder fitting and
valve stem!) and tubing after connection. If the tubing leaks at the fittings, use special hose clamp pliers to furthe r
squeeze the stainle ss clamps. If no clamp pliers are available, a pair of side cutters can be used to further squeeze and
crimp the fitting clamps. If side cutters are used to re -crimp the hose clamp, use only the pressure neede d or you may cut
the clamp. The clamps are tough stainless steel, but it is possible to cut them if care is not exercised. If sealing cannot
be achieved, use additional worm ge ar type hose clamps to completely seal the tubing. If fittings do not seal with mo der-
ate pressure, remove and inspect fittings for burrs, de formation or wear (including cylinder threads). Before connecting
the regulator to the cylinder, stand to the opposite side o f the opening and quickly open and close the valve to create a
blast which will purge any dirt or particles lodged in the cylinde r threads, in the valve or on the seat. IMPORT ANT! Use
safety glasses when connecting and disconnecting regulator or purging cylinder. Always stand out of the direct line of the
regulator as much as possible when opening the cylinder valve. If cylinder valve is le aky o r faulty, return the cylinder
immediate ly to the distributor for te sting or repair. Always keep cylinders chained up. Never we ld o n a cylinder. Keep
cylinders out of the immediate weld area, especially when molte n metal or sparks are present. Keep caps installed on
cylinders when transporting. Keep cylinders secure d when transporting in vehicles. Do not transpo rt cylinders in en-
closed vehicle s. Do not transport cylinde rs with the regulator installed.

The regulator is calibrated in Cubic Feet Per Hour (CFH) in the US and Canada. In other regions the gas flow rate may be cal ibrat-
ed in Liters Per Minute (LPM). Adjust the regulator flow rate while gas is flowing only. Ball will not float unless gas is flowing.
Once gas stops flowing, ball will drop slowly. If ball is floating and no gas should be flowing, check for leaks or stuck so lenoid.
Gas flow rate requirement will be affected by joint design, fit up, position, cup size, Amp settings, metal type, drafts, etc.
CAUTION! WHEN OPENING THE CYLINDER VALVE! ALWAYS OPEN CYLINDER FULLY. SHIELDING GAS CYLINDERS ARE DE-
SIGNED TO BE COMPLETELY OPENED OR CLOSED OR LEAKAGE FROM THE VALVE STEM MAY OCCUR. Use common sense:
Stand to the opposite side of the regulator, on the other side of the tank while opening the cylinder valve. If a regulator or gauge
were to be damaged or develop a defect, the regulator may send parts flying at high speed, causing serious injury or death if you
are in the direct path. Allow the regulator to pressurize slowly before standing in front of it to make any adjustments.
WARNING! DO NOT USE OR ATTEMPT TO REPAIR OR SERVICE ANY DAMAGED REGULATOR OR SERIOUS INJURY OR DEATH
MAY OCCUR! ALWAYS CLOSE THE CYLINDER VALVE WHEN NOT IN USE. IF THE CYLINDER VALVE OR REGULATOR VALVE
IS LEFT OPEN, THE CYLINDER CONTENTS MAY ESCAPE AND FILL THE ROOM. ARGON WILL DISPLACE THE OXYGEN IN THE
ROOM AND MAY CAUSE ASPHYXIATION BEFORE YOU REALIZE IT! DO NOT RISK IT!
