The "Gas Blast" at MIG Starts, Causes Problems:

1) Shielding Gas Waste - Typically Half the Gas Being Used!

2) Inferior Weld Start Quality - Since Air Enters the Turbulent Shielding Gas Stream the High Flow Creates.

Our Patented Gas Saver System (GSS) Improves Weld Start Quality

and Cuts Gas Use in Half by Eliminating Waste.

Argon Prices Doubled in the Past Two Years.

Prices Start at $55.00; 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 as important than the substantial shielding gas waste reduction!

Greg Pepitone sent an email (with pics of his '33) asking a question about MIG shielding gas flow rate.  He ended his email with the following:

"A number of years ago I purchased a Portable Flow Meter and Gas Saver System. Great products not ever a problem. I did indeed find the Argon gas usage was extended - may I say well done.  Thanks for a great product, it did make a difference and I have recommended it to friends just short of twisting arms. However, the old story about leading a horse to water with some of the hard heads of the world!"

Note, Greg also purchased our book  "Advanced Automotive Welding" and emailed; "Thanks for writing the book."

A customer recently said, "Like the saying, 'Build a Better Mouse Trap and People Will Beat a Path to Your Door;' I can't understand why every MIG welder doesn't use your great Gas Saver System (GSS)?"  
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.
