22-30-580 - Miller 20 Series Flowmeter Regulator, Argon/CO2/Helium, CGA 580 Connection

Reliable Shielding Gas Delivery for Perfect Welds

Every welder knows that consistent shielding gas coverage is the secret to a clean, porosity-free weld. The Miller 22-30-580 Flowmeter Regulator is built to give you exactly that confidence, whether you are TIG welding aluminum with pure Argon or MIG welding steel with a CO2 mix. This isn't just another fragile gauge; it is a heavy-duty tool designed to survive the daily grind of a welding shop. The first thing you will notice is the rugged aluminum housing that protects the flow tube. We have all seen flowmeters get smashed by a swinging cable or a tipped piece of metal—Miller has designed this unit to withstand those accidental knocks so you don't have to replace your gear halfway through a job.

Reading your gas flow has never been easier. The flow tube features a high-visibility green background that makes the scale pop, allowing you to check your settings from a distance or in low-light conditions. But the real game-changer is the accuracy. Have you ever had a tank that wasn't sitting perfectly level? On cheaper regulators, the ball inside the tube can drift to the side, giving you a false reading and causing you to waste expensive gas. Miller's exclusive self-centering ball guide keeps the ball floating straight and true, ensuring that the flow rate you see is the flow rate you get. This means better weld quality and more money in your pocket from gas savings.

This regulator comes ready to work with a standard CGA 580 connection, fitting most Argon, Helium, and Nitrogen cylinders. It is preset to 30 PSIG, which is the sweet spot for most welding applications, preventing the massive pressure spikes that can cause turbulence at the weld puddle. The tube is clearly marked with separate scales for Argon, CO2, and Helium, so you don't have to do any mental math to figure out your flow rate. Plus, with Miller's Sure Seat™ technology, a built-in filter keeps dirt and metal shavings out of the regulator's sensitive internal parts, preventing leaks and extending the life of the tool. Covered by Miller's legendary True Blue® 3-Year Warranty, this is an investment in your craft that pays for itself in reliability and performance.
