Minnesota Welding School Installs 75 Gas Saver Systems
and cuts shielding gas use over half

MiinThe 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!

SCFlorence 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?

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.
