GFT 191.0013 Gas Flow Tester Argon / Co2 Take Control of Shielding Gas Cost!Test Gas Flow Rate at the TorchHere's the simple, low cost, way to test every welder and gas flow regulator in your shop to save big on wasted gas. Do it using our GFT style gas flow gauge / checker!With the wire feed drive roll open and the weld gun pointed upward, hold the Gas Flow Checker against the end of the weld gun nozzle and squeeze the trigger of the welding gun. Gas flowing through the gun pushes the stainless steel ball up the acrylic tube. Gas flow rates are read on the scale printed on the acrylic tube Argon / Co2 / Nitrogen in LPM (LPM / .472 = CFH)This is a great way to test for gas regulator accuracy at the same time.GFT Measures the actual flow of shielding gas at the MIG / TIG torch nozzle, allowing adjustments to be made at the cylinder gauge if necessary.AE-GFT An economical solution for improving overall welding performance. This easy to use device will take the guesswork out of optimizing your welds, and save on shield gas cost.For production applications the benefits of documenting flow rates at the torch – will pay off with reduced weld variations and lower gas usage.The Unit Measures Argon and Co2 Flow Rates up to 25 L/ min (53 Cu Ft / h) Measures in Liters/Per Minute. To Convert to L per min to Cu Ft, Divide - L/ min by .472 = Cu Ft / h Examples: 3 L/ min = 6.4 Cu Ft / h 5 L/ min = 10.5 Cu Ft / h 10 L/ min = 21.0 Cu Ft / h 15 L/ min = 31.8 Cu Ft / h 20 L/ min = 42.4 Cu Ft / h 25 L/ min = 53.0 Cu Ft / h
