The Blast of Shielding Gas Exiting a MIG Gun Nozzle at a Weld Start Causes Problems:

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

2) Inferior Weld Quality - Since Air is  "Pulled" Into The Turbulent Shielding Gas Stream

1. What is the Ideal Gas Delivery System? 

2. Is the Main Reason for Gas Surge Hose Expansion?  No- Hose Expansion May Only Cause ~13%; See What it is!

3. Why is Enough Extra Gas Needed at MIG Weld Starts?

4. How Does Automatic Flow Compensation Work and Why is a Minimum of 25 psi Regulator Pressure Needed to Achieve it?  See Video

5. What MIG Flow Rate Should I use?  See Video

6. What is the Payback of the Gas Saver System? Note: It is Usually Measured in Weeks However When Adding New Welding Machines, it Could Be Immediate!- -See Payback Calculations and "Just Do It !"

7. Why is My Existing Gas Delivery Hose a Wasteful 1/4 " ID?

8. Why do Simple Orifices Mounted at the Feeder Not Work to Reduce Gas Waste?  Why They Give a False Savings Impression!  See Video

9. What Problems Occur if Low Pressure Devices are Used?

10. What About Using Orifices To Control Flow at a Pipeline Gas Supply?

11. If on Pipeline Gas Supply What Corrections In Flowmeter Readings Are Needed for Pressure Changes?

12. The Gas Surge Exiting My MIG Nozzle at the Weld Start Only Lasts a Short Time-Why is That A Problem with Weld Quality?
