 Female CGA
"B" inlet gas fittings are on most Lincoln, Miller, Hobart, ESAB, Linde, L-TEC
and most US
produced wire feeders, welders. Female CGA "B" fittings are also on most US produced regulator
flow controls and flowmeters
(see note about Hobart Handler below.) The GSS
comes with the male counterpart CGA "B" fitting installed on both ends.
Simply unscrew the existing shielding gas delivery hose and screw in the GSS.
Pictures above show a GSS installed on a Lincoln and another on an ESAB
industrial wire feeder. It simply
screws into the female connector on the back. The following are two
examples on smaller size welders: |
|
A 25 foot long GSS
(part #; FB25)
used in my Home Shop with a large gas cylinder chained to one wall and
welder on a movable work cart.
Longer systems can be supplied if needed. The 160 cubic foot cylinder
is the largest my local distributor offers for sale versus renting.
See Perry Thomasson's home shop and comments about
his 50 foot long GSS. |
|
 This Lincoln
180 amp Welder uses a 4 foot GSS
(part #; FB4) to
reduce gas usage and improve weld start quality.
It is simple to install; just unthread existing gas delivery hose from flow
control setting regulator/flowgauge to welder and screw in
GSS which comes with the same
industry standard CGA 032 "B" male fittings.
One end of
GSS has a Mylar label indicating it screws into
feeder-welder.
With the many
short welds and tack welds made in home shops the gas cylinder will last
more than twice as long and give twice the warning of running out. A
major benefit on a weekend! |
Sketch on right shows the connections. Note male fitting
are supplied on
both ends of the GSS hose. Prefitted
GSS
FB3, FB4, FB6, FB12, FB25 use this connector.

Two Solutions for Wire Feeder/Welder or Gas Supply
That Has a Hose Barb
or a Hose Comes Out of the Welder: |
The wire feeder shown at left has a hose barb connector to
attach the shielding gas delivery hose (see yellow arrow.) This may
also be an internal connection with the hose simply exiting the case of the
feeder or welder. It
could also be a quick disconnect fitting or anything other than a CGA 032, "B"
fitting.
There are two methods of installing the GSS
in these situations or where the feeder may have a CGA 032 connector
but the gas supply does not. For example, on a gas pipeline
where instead of a CGA 032 female connector being available at the pipeline a
simple hose barb is used.
|
Either of the Following Two
Installation Methods Can Be Used When a CGA Fitting is Not Available.
Both Perform Equally
to a GSS with CGA "B" Fittings: |
|
Method 1
We Can Provide
the GSS
with Splice Fittings at
the Same Price as CGA Fittings (Photo Below Right .)
Instead of supplying two CGA
032 fittings on the GSS (for
example, if your
welder has a hose barb and your regulator/flowgauge uses a CGA 032 female
"B" fitting) we
will install a Splice Fitting on the hose end where you do not have a female
CGA 032 "B" fitting.
You just cut the existing hose close to the feeder/welder or gas regulator/flowgauge
and insert the hose barb at the end of the GSS
and tighten the supplied screw clamp. The price
will be the same as a fitted hose with CGA fittings, i.e. order a FB3,
FB4, FB6,
FB12 or FB25 and send an email about the special need. Just send
the email to
TechSupport@NetWelding.com
when you place your order and let us know which end or if both
need Splice Fittings. NOTE: the fitting on the feeder/welder end
incorporates a surge limiting orifice so we must know which end will have
the Splice Fitting. Include you're shipping address so we can
match your email with the PayPal order.

Method 2
Use
Special Adapter
An
adapter
connection method was developed for an automotive manufacturer who uses
some wire feeders from Japan. These wire feeders do not use the CGA
032 "B" connector. All flowmeters at their gas supply pipeline were produced in the
USA and use the CGA 032 "B" connector. Also the fabricator wanted
the ability to change wire feeders quickly, interchangeably with US made
feeders. We developed a connector which
solved the problem. They cut the existing shielding gas delivery hose
close to the feeder and installed our WAT-SFIT-4 connector into their existing
short length 1/4 inch ID hose. |
|
 This
adapter fitting has a hose barb on one end and a
female CGA 032 "B" connector at the other. They used standard GSS hose with CGA
"B" connectors
and simply screw the feeder end into the WAT-SFIT-4 or their other US
made wire feeders. The metal to metal
seats on CGA "B" connectors are precision made and less likely to leak. An
adapter is also available for an existing 3/16 inch ID hose, part number
WAT
SFIT-3. If you
would like to use this approach, a WAT-SFIT-4 is available on
the purchase page and fit either end of
a GSS hose.

Contact Us if You Need the WAT-SFIT-3 |
Have a Dual Wire Feeder
 with
Two Gas Inlets?
Do you use the same shielding gas for both sides? We
have a special arrangement for this situation. It is two short GSS's
connected to a brass TEE fitting that has a female CGA Inert Gas 032 "B" fitting
inlet. It is part number WAT-DFT. It comes
standard with 1 foot long GSS's
with end fittings that include peak flow orifices.
 You
will need to add a GSS to the
inlet of the length to go from the TEE fitting to the gas control device at
the pipeline or cylinder. Order the required length.
We will equip the system with the proper "B" fittings.
Since we are
asked, from time to time, if an FB3 can be connected to an existing
gas delivery hose and have the GSS
benefits. The answer is no! The gas savings comes
primarily from the 75% reduced gas volume in the GSS
hose compared to a standard 1/4 inch ID hose. The GSS needs to be full
length.
If you
need this approach,
Contact Us. |
|
Using
a Gas Mixer?
We have supplied a
number of customers with GSS's
that are using gas
 mixers .
Depending on the type of mixer used, such as simple TEE mixers, to achieve the gas saving and performance benefits,
it may be necessary to use
GSS hose from gas supplies to the mixer and from the mixer
to the TIG or MIG welder. More expensive mixing devices may only need the
GSS from the mixer output to the welder or wire feeder.
Email with the details of what mixer is being used and the lengths of the hoses
employed and we'll quote what to
purchase. |

Hobart Handler
Jason Insley purchased a Hobart Handler that included a Smith
 Regulator/Flowgauge.
The welder had a female CGA 032 "B" fitting but the gas Regulator/Flowgauge
had a hose barb fitting. Jason removed the barb fitting and although it had
a thread that looked similar to a CGA "B" fitting thread (it is not, it is
a pipe tread) he found, as
expected, it had a flow control orifice built into the hose barb fitting
inlet! See the top left photo Jason sent. This must remain in place to
properly control flow. Jason ordered our part number FB3 (3 foot
GSS.) In an email he requested our standard CGA 032 "B" male fitting on
the welder end and a Splice Fitting on the regulator end.
Jason emailed the pictures left and commented:
"Everything work fine. And my weld starts have definitely improved since
installing the GSS. Thanks again."
Need a Splice
Connection on
either end? Just email what you need when you place the order. A
splice connection can be placed on either or both ends for the same price. The
one on the welder end has the same peak flow, surge limiting orifice as the
"B" fitting.
Performance is identical.
Still Have A
Question About The Fittings Needed?
Perhaps this
picture will help.
The picture
shows two CGA 032 "B" fittings at different angles. Note the ends
have
a rounded shape. It matches the shape of the female fittings that are
on most US manufactured MIG and TIG welders and MIG wire
feeders. A female CGA 032 "B" fitting is also used on the outlet of
most US made Regulator/Flowmeters, and Regulator/Flowgauges. Note, the
nut is separate and it Does NOT have a tapered pipe tread. It
has a straight thread and only tightens the hose barb end against the mating metal seat in the
female fitting on the welder, feeder and gas supply. If the fitting on your welder or
regulator is one piece, i.e. with barb and nut together, like the one that came
with the Hobart Handler above, it is likely NOT a CGA fitting so a Splice
Fitting should be ordered for that
GSS hose end.
Email If You Still Have a Question |
NOTE: Regulator/Flowgauges, (photo below left),
like the one on Jason's welder operate by setting gas pressure ahead of a
very small orifice. They are calibrated in cubic feet per hour (CFH)
NOT psi. They use a principle called
"Choked Flow"
which limits the velocity of gas through the small orifice to the speed of
sound at
 the
pressure setting. Depending on the orifice size, pressures
typically vary from 40 to 60 psi. That small orifice may be in the
outlet fitting, like the one on Jason's welder, or could be inside the
regulator body. When gas is flowing, the gas pressure drops across the
orifice to typically 3 to 6 psi in the gas delivery hose. When welding
stops, gas continues to flow through the orifice and quickly fills the hose
with 4 or 5 times the amount of gas until the pressure equals the pressure
setting. That stored excess gas is what causes the "Blast of Gas"
at each weld start or when you are just inching the wire to cut off the end
or position it in the weld joint. This not only wastes gas but pulls
air into the gas stream creating excess spatter and possibly internal weld
porosity. |

HOME SHOPS With
Small OD Gas Hose
Does your welder
have a very small (5/32 inch) outside diameter gas hose exiting the case? Would you like to extend it to use a larger
gas cylinder?
A special PrestolokR
fitting allows the GSS hose to connect to
the nominal 5/32 inch outside diameter gas
hose supplied with some smaller welders and regulators (see photo on left). We can
supply that fitting on the welder end and a CGA 032 "B" fitting on the end that fits the
new cylinder gas control device you'll purchase with the larger cylinder.
Or we can supply the PrestolokR
on both ends of the hose. Just cut the original hose and splice in the GSS.
It will include a surge restriction orifice on the welder end. With this kit a large
cylinder can be purchased and chained to the wall of the shop and the
welder moved 25 feet away if you purchase an FB25 and ask for the
fittings you need to be installed.

 Using
a TIG Torch with a Foot or Hand Off-On Gas Control?
Our Gas Saver System
(GSS)
can save money and improve weld starts. The initial gas flow surge
at a TIG start, in addition to wasting gas, can cause the arc to move unpredictably,
This movement is especially a problem at low starting currents. The
turbulent shield created by the gas surge pulls air into
the shielding gas stream causing contamination not just of the weld but also the tungsten electrode,
shortening life and requiring more frequent dressing. Our
GSS
eliminates the excess "gas blast" at each weld start and limits the peak surge flow rate. It still
quickly supplies a controlled amount of extra gas to purge the TIG cup and weld
start area. It can also reduce the needed preflow time often used in attempt
to counter the high initial gas surge. The patented
GSS
will not interfere with your flow settings
and has no moving parts to maintain or adjust. Just install it
between your cylinder
(or pipeline supply) and welder (or TIG box) that contains the gas
control solenoid (See Schematic).
Here is a comment from Terry,
who owns a FAB shop in California, about the use of our GSS for his
TIG welders:
"Received and tested the GSS and compared it to a "low pressure gas saver" on
my TIG welders where we mix helium into the argon stream. Mixing the two
gases is particularly difficult with the low pressure device. Your hoses
eliminate the difficulty and produce the same reduced surge and gas savings
results."
Terry
has purchased GSS's for his TIG and MIG welders.
Note: See these links
providing information about low pressure "surge reducing devices" which
create more problems than they solve!
