FLOW RATE INFO

SETTING MIG SHIELDING GAS FLOW RATES

Find Information About Setting MIG Shielding Gas Flow Rates, Reducing Waste and Improving Weld Quality.

See Web Page With Suggested Flow Rate Chart

	See Causes for MIG Gas Usage Being Over 3 Times What Should Be Used.
	The Manager of Welding R&D for the Leading Shielding Gas Producer, Praxair, Says Using Over 50 CFH Gas Flow - "Creates Weld Defects."
	Osborne Reynolds in 1893 Found That a Clearly Defined Velocity Exists Where Gas Flow Goes From a Smooth Laminar Flow Mode to Chaotic Turbulent Flow.
	In Pipeline Shielding Gas Supply, Pressure Changes Cause Significant Flow Changes. In Addition, if Flowmeters Are Used, Many Are Calibrated at 25 psi and Pipeline Pressures Are Often 50 psi. In That Situation a Flow Set at 31 CFH Will Actually Be Flowing 40 CFH- SEE WHY.

	See Ideal Gas Delivery System
	Why Orifices Placed at Wire Feeder to Control Flow Are Often Justifiably Rejected By Welders
	Using an Orifice to Control Flow at Pipeline Drop is "Fine." Combined with The Gas Saver System Sufficient Extra Gas is Provided at the Weld Start to Purge the Weld Start Area. Pressure is Maintained to Retain "Automatic Flow Control."

	Gas Control System Must Provide Some Extra Gas at Weld Start
	Pressure in Flow Control Devices and in Pipelines Must be Over 25 psi to Provide an Important Feature the Inventors of MIG and TIG and Early Designers of Shielding Gas Control Understood and Used and Some Have Forgotten - "AUTOMATIC FLOW COMPENSATION !"
