8-1441 - Tweco Argon/CO2 Flowmeter with Dual Scale Tube

Dial in Your Perfect Flow

As a welder, you know that shielding gas is the lifeblood of a clean weld. Too little, and you get porosity; too much, and you create turbulence that pulls in atmospheric air—not to mention wasting money. The Tweco 8-1441 Dual Scale Flowmeter is designed to take the guesswork out of your setup, giving you a clear, precise reading of exactly how much Argon or CO2 is hitting your puddle.

One of the standout features of this flowmeter is its durability. We've all seen glass flow tubes shatter when a regulator gets knocked over or a tank is moved roughly. Tweco solved this by using a tough Lexan flow tube. It’s impact-resistant and stays clear, so you can actually see the ball floating without squinting through scratches or cracks. The dual scale is a huge time-saver if you switch between processes. Whether you are TIG welding aluminum with pure Argon or MIG welding mild steel with C25 or straight CO2, this single unit gives you the accurate SCFH readings you need right on the tube.

Setting it up is straightforward. It features standard threads that fit most regulators and machine inlets. The adjustment knob is smooth and responsive, allowing you to dial in that perfect 15-20 SCFH (or whatever your procedure calls for) with ease. No more tapping on the gauge to get the needle to settle—the ball floats steadily to show you the real-time flow.

Whether you are setting up a new rig in your garage or upgrading the station at your job, the Tweco 8-1441 is a smart investment. It helps you save gas by preventing over-flow and ensures your welds are protected by the right amount of coverage. It’s a small tool that makes a big difference in the consistency of your beads.
