22-80-580-6 - Miller 20 Series Argon/CO2 Flowmeter Regulator with 6ft Hose, CGA 580

Reliable Gas Flow for Perfect Welds

Upgrade your welding setup with the Miller 20 Series Flowmeter Regulator, a heavy-duty solution designed to take the guesswork out of shielding gas management. Whether you are MIG welding steel or TIG welding aluminum, consistent gas flow is critical for preventing porosity and ensuring a strong bead. This regulator delivers exactly that, combining professional-grade accuracy with a rugged design that can withstand the daily knocks and bumps of a busy welding shop. It comes ready to use with a 6-foot hose, so you can hook it up to your Argon or CO2 tank and get to work immediately.

Built Tough for the Real World

We know that welding equipment needs to be tough. That’s why Miller ditched the fragile glass tubes found on cheap regulators and used a shatter-resistant polycarbonate flow tube. It is protected by a sturdy aluminum housing that keeps it safe if a tank gets jostled or a tool falls nearby. The scale is printed on a high-visibility green background, making it easy to check your flow rate at a glance, even if you have your helmet raised in a dimly lit corner of the shop.

Stop Wasting Gas

One of the biggest hidden costs in welding is wasted shielding gas. Standard flowmeters can give false readings if your tank isn't perfectly level, leading you to turn up the flow "just to be safe." The Miller 20 Series features a self-centering ball that gives you an accurate reading even if the regulator is tipped. This means you use exactly the amount of gas you need—no more, no less. Over time, the savings on gas refills can pay for the regulator itself.

Long-Lasting Performance

Regulators often fail because dirt and metal shavings from the tank valve get inside and damage the seat. Miller’s Sure Seat™ technology filters out these contaminants before they can cause harm. This ensures your regulator lasts longer, doesn't leak, and provides smooth, consistent flow every time you pull the trigger. Backed by Miller's True Blue® 3-Year Warranty, this is an investment in quality that gives you peace of mind for years to come.
