Minnesota Welding School Installs 75 Gas Saver
Systems
and cuts shielding gas use over half
 The welding
department at a technical college initially installed 30 Gas Saver
Systems from their liquid gas feed
piped supply to their TIG welders and to gas mixers then MIG welders.
After three months of use this is what the instructor reports:
"
We went from using 1 Dewar of Argon
(liquid
gas cylinder)
a week to the same
size Dewar lasting almost 3 weeks. The companies that sit on
my advisory committee are becoming very interested in this upgrade. I will
keep you posted"
They purchased 15 more Gas Saver
Systems for the 2014 -'15 school year and another 30 systems in 2019.
Note: An advisory committee member, a Caterpillar Tractor plant, has purchased 100 Gas Saver
Systems. In 2018 they added 20 more welding machines and bought 20 more; in 2019 another 20!

 Florence Darlington Technical College
Installs Over 60 Gas Saver Systems
The Many
Short Welds and Tack Welds Made in Welding Schools Allow Our Gas Saver System to
Reduce Gas Use by Over 50% with Improved Weld Starts! |

One of the welding labs at FDTC in SC. They currently have over 80
students in the welding program |
All 61 MIG welders had
GSS's
installed. They simply replaced the old gas delivery hoses. |
|
 The
majority of the wire feeders and welders in the school have standard Compressed Gas Association
female inert gas fittings (CGA 032; "B".)
Our standard
GSS
hose (FB3, FB4, FB6 etc.) comes with male CGA 032 "B" fittings preinstalled on
both ends (Note, one end has our peak flow limiting orifice and is labled as such.) All that is required is to simply unscrew the original
gas delivery hose from the gas cylinder regulator/flowmeter or a flow control with two gauges, one labled CFH, to the
feeder/welder and screwing in the
GSS.
See below for a few welders that needed different
fittings. |
Some welders at FDTC
had a 1/4 inch hose coming from inside the combined Power /Feeder
welder. The gas delivery hose was attached to a barb fitting on the
gas solenoid inside the welder. For these units it was a simple
matter to cut the original gas hose close to the outside of the welder and use
our WAT Splice Connector to
install the
GSS.
As with standard "B" fittings, a surge flow restrictor is built into the Splice fitting. Note we typically supply Splice Fittings for GSS's used on welders and regulator gas controls produced outside the US that often employ a simple hose barb connection.
A
GSS can be supplied with a CGA fitting on the Gas
Supply end and a splice fitting on the Welder end, or
visa versa if needed. |
Welders or Students Setting Shielding Gas Flow
to High?

OPERATE A WELDING SCHOOL OR WELD TRAINING
FACILITY?
Great Idea
- from a welding school instructor. Welds made at these locations are of short
duration and include many tack welds. The start surge wastes a great deal of shielding gas. Shielding
gas savings can easily exceed 50%.
Also, even though duty cycle is low, many
cylinders are rented. Since the gas usage is significantly reduced with
the Gas Saver System (GSSTM)
a school can get by with fewer cylinders. Simply put two welders on one
cylinder and reduce the rental bill ! Super Simple!
|
 -Dual regulator flowmeters are often used when a back purge gas line is emplyed. See photo left. Just connect two GSS's to
the two outlets and save cylinder rent! Flows can be set independently. You'll be changing cylinders no more
frequently than at present. Concerned that students are setting
too high? Our Flow Rate Limiter will fit this model!

Book Review by a Race Car Builder:
Thank you for the wonderful book that you wrote. The content is possibly
one of the best written and cogently assembled pieces of welding instruction
that I've ever read.
I have literally dozens of books on welding that span a good
5 or 6 decades. Some of the better ones were written back in the 40's for
training the wartime workers. It's amazing to me that it took over 60 years
for a book to be published that is comprehensive and comprehendible that
explains in everyday language, the latest techniques in the welding arts and
sciences. The coverage of the subject was more complete than I have ever
seen. This is a classic, and sure to be a benchmark reference book for years
to come.
I have recommended the book to my membership at the website
and continue to promote it wherever I go.
I know that ADVANCED AUTOMOTIVE WELDING will be
a huge success, and we are honored to have been a small part of it. Please
don't hesitate to call if there is every anything that we can do for you.
