Shielding Gas is Getting More Expensive!
Our patented Gas Saver System (GSSTM) cuts gas use in "HALF" and improves weld quality. You'll only need half the refills!
Prices Start at $65, Less Than a Typical Gas Refill !

ALERT: AIR PRODUCTS raising Argon prices 20% and AIRGAS 15% March 2017. They join PRAXAIR who raised Argon prices 15+% in January. All have doubled prices in the past few years! Argon is predicted to stay in short supply!


The "Gas Blast" at MIG Starts, Causes Problems:
1)Inferior Weld Start Quality - Since Air Enters the Turbulent Shielding Gas Stream the "Gas Blast" Creates.
2) Shielding Gas Waste - Typically " Half " the Gas Being Used!

See Why “Automatic Flow Compensation” is Necessary But Causes About Half the Gas Used to Be Wasted!

Beau Straley Improves Weld Quality and Saves Over 60% of shielding gas. He purchased a 4 foot long Gas Saver System (GSS)  and reported these gas results:
"I received the  GSS in the early part of a large project, building a 12’ x 24’ steel building. Before installing it on my Miller 211C, I had completed about 30% of the total welds, and had consumed approximately 400 psi of my Argon/25% CO2 gas mixture.   As my project progressed I could tell I was consuming much less gas, so I increased the flow rate and my weld quality improved.  In the following three months I finished all the remaining welds.  The remaining 70% of the welds required only an additional 300 psi consumption of gas.   Improvement in my welding technique accounts for part of the gas savings, however, considering I more then doubled the number of welds, while reducing my gas consumption by 25%, I’d say the GSS is a real winner!
Before I installed the GSS I was being stingy with the shielding gas flow, and the poor quality of my welds proved that.  With the GSS installed I was confident that I was not wasting gas, and increased the gas flow rate. The result with that the appearance and quality of my welds improved dramatically.  It not only saved shielding gas, but it increased my confidence. That’s a winning combination in my book!
Thank you for a wonderful product that actually does what you say it will."

Crunching the math for Beau Straley's gas usage: Over Twice The Welds Made/Used 75% of the Gas or 50%/75% = 67% Less Gas Used with GSS

Our Patented Gas Saver System (GSS) Improves Weld Start Quality and Cuts Gas Use in Half by Eliminating Waste.

GSS Prices Start at $65.00; Less Than the Cost of a Cylinder Refill!

CAT2A Caterpillar Tractor plant recently reported improved starts with less internal porosity achieved with Gas Saver Systems (GSS) installed on all their MIG welders. Savings in rework costs were as important than the substantial shielding gas waste reduction!

A customer recently said, "I can't understand why every MIG welder doesn't use your great Gas Saver System (GSS)? Like the saying, Build a Better Mouse Trap and People Will Beat a Path to Your Door." 
I told him that only fits if they know they have MICE! 

Bottom Line:

If you are not using our low cost, patented GSS you have "mice!"  It saves about half the shielding gas used by eliminating waste while improving start quality.   Compared to other devices tried in the past, welders like the improved starts!!  Over 10,000 GSS's are in use at industrial fabricators such as Air Products, Boeing, Caterpillar Tractor etc. See Partial User List.

"Flow Rate Limiter" - a Perfect Complement to Our GSS

Save Even More Gas With Our Patented Flow Rate Limiter (FRL)

The FRL is our latest shielding gas saving patent.  It simply clamps on to and locks the flowmeter knob, preventing changes.  No alterations are made to the flowmeter.
