22-80-320 - Miller 20 Series CO2 Flowmeter Regulator, 10-80 SCFH, CGA 320

Precision Gas Control for Professional Welders

Stop wasting money on shielding gas and start getting the most accurate readings possible with the Miller 22-80-320 Flowmeter Regulator. Designed for the serious fabricator, this regulator solves the two biggest headaches in gas management: durability and accuracy. If you are welding with CO2, you know that regulator freeze-up and debris can kill your gear. Miller’s Sure Seat™ technology filters out contaminants before they damage the seat, ensuring your regulator lasts longer and performs better, even during long weld cycles.

Why is this flowmeter different? Most competitors use a standard flow tube where the ball can bounce around or float off-center. When that happens, you might think you are flowing 20 CFH when you are actually flowing 40 or 50. That is money flying out of your nozzle. Miller’s exclusive self-centering ball guide keeps the indicator perfectly vertical, giving you a true reading every time. This means you use exactly the amount of gas you need—no more, no less—saving you significant overhead costs over the life of the unit.

Built to survive the shop floor, the 22-80-320 features a tough aluminum housing that guards the flow tube against knocks and drops. The tube itself is made of shatter-resistant polycarbonate, so you don't have to worry about glass shards if an accident happens. The high-visibility green scale makes it easy to check your settings from across the booth. Whether you are running pure CO2 for deep penetration MIG welds or need a reliable regulator that can handle the rigors of daily industrial use, this Miller 20 Series regulator is the trusted choice. Backed by Miller's True Blue 3-Year Warranty, it is an investment in quality that pays for itself in gas savings.
