The Blast of Shielding Gas Occurring When a MIG Gun Trigger is Pulled Causes Problems:

  1. Significant Shielding Gas Waste 

  2. Inferior Starts Since Air is "Pulled" Into The Resulting Turbulent Shielding Gas Stream

 Our patented "Go Green"--Gas Saver System  eliminates these problems and saves from 40 to 60% of gas use! 

That Saves 8 Tons of CO2 or Argon Shielding Gas per Year per MIG Welder - SEE BELOW.

If Excess Gas  Flow Is Such A Problem, Why Has My Gas Supplier Not Told Me? CLICK To See.

The Gas Saver System (GSS):

bullet

Is simple to install; just replace the existing gas delivery hose from gas supply to welder or wire feeder with our prefitted GSS hose system.  It reduces the gas surge volume by 80% and limits peak surge flow rate.  Works with existing regulator or flow control. You still control the steady state flow.

bullet

Is inexpensive.  A commonly used 6 foot GSS system (Part Number FB6 ) cost less than $75 and will typical cut shielding gas use by 50% so you'll have a very quick payback!

bullet

Reduces the gas surge at the start producing better shielding for sounder welds with less starting spatter so wasteful repair or grinding may not be needed.

bullet

It reduces the CO2 waste going into the atmosphere (even 25% if using 75 Argon/ 25 CO2 ) and also the number of times your gas supplier will have to expend energy to fill and delivery the ~200 pound cylinders or to delivery to your bulk tank  

(Note: Using  MIG gas waste information published in an industrial magazine quoting a Praxair representative regarding their plant survey finds and validated with our own observations- one industrial MIG welder typically wastes over 150,000 ft3 (CF) of  shielding gas per year.  If using straight CO2 that's over 16,000 pounds (8 tons!) of wasted  per welder per year! 

If your using Argon gas mixtures your wasting a similar weight of gas per year per welder and  have similar distribution and much higher production electric energy costs (with accompanying CO2 pollution) SEE Why. )

 

 

How Much Shielding Gas is Wasted on Each Weld Start or Torch Pull? 

 

bullet

Up to 6 times the gas hose volume (from gas supply to welder / feeder) ; See Why.

How does the GSS work?

bullet

If your using Argon  mixtures you also have excess gas surge since regulator/flowmeter pressures range from 25 to 50 psi still 8 to 15 times that in the delivery hose when welding!  Why are pressures designed to be a minimum of 25 psi?

CALCULATION OF CO2 WASTE:

Assumptions and Calculation:

bulletIndustrial MIG welder operating at 50% duty cycle with flow setting of 35 ft3/hr (CFH) on flowmeter
bullet4 times this amount of shielding gas needed is wasted.  See References below which states up to 5 times needed is wasted.
bulletThen 40 hrs/wk * 50% duty cycle * 50 weeks = 1000hrs/year arc-on time.
bulletWaste consumption = 35 ft3/hr *4* 1000 hrs/yr = 140,000 ft3 CO2/year
bullet140,000 ft3 CO2 * 0.115 lb CO2/ft3 @ STP (Standard Temperature and Pressure) =
bullet16,100 lbs = 8 tons of CO2 wasted per year
bullet 8 tons/yr wasted.

  2. Weber, R., How to Save 20% on Welding Costs. Trailer/Body Builders, Volume 44, Number 3, January 2003 (Praxair Representative states, their market survey findings show the average fabricator consumes 30 cubic feet of gas per pound of wire which 5 times what is needed.)
Welders Setting Flow Rates Too High? 

We have measured flow rates above 125.CFH when the flow ball is pinned to the top of the tube!  Anything over about 50.CFH is pulling moisture laden  air into the shielding gas stream and causing internal if not visible porosity!  The flow rate may be outside the variable range specified in Procedure Qualifications.
