OVERVIEW

Reliable Shielding Gas Flowmeter for MIG & TIG

Upgrade your welding setup with the Smith H2231A Standard Duty Flowmeter, a versatile and durable solution for managing your shielding gas. Whether you are welding aluminum with pure Argon, stainless steel with Helium mixes, or mild steel with C25, this flowmeter has you covered. It features a clear, easy-to-read triple-scale tube that displays flow rates for Argon, Helium, and Argon/CO2 blends directly, saving you time and reducing setup errors.

Built for the Shop Environment

Accidents happen in busy shops, but your flowmeter shouldn't be the victim. The H2231A is constructed with a shatter-resistant polycarbonate flow tube that is far tougher than glass. It is designed to operate at 50 PSIG, making it a perfect replacement or upgrade for many standard regulator bodies and pipeline outlets. One of the most frustrating issues with cheap flowmeters is the ball sticking or floating against the wall of the tube, giving inaccurate readings. Smith Solved this with their unique ball-centering technology, which keeps the indicator floating freely and accurately, ensuring your gas coverage is exactly what your weld puddle needs.

Easy Installation and Long-Term Value

This unit comes ready to install with a 1/4" NPT female inlet, allowing it to easily screw into most standard regulator bodies or pipeline drops. The output connection is a standard 5/8"-18 RH female fitting, compatible with standard inert gas hoses. With a packless O-ring seal design, you won't have to worry about leaks developing over time due to dried-out packing. Invest in quality equipment that lasts; the Smith H2231A is backed by a 3-Year True Blue Warranty, giving you peace of mind and consistent performance for years to come.

FAQ

The Smith H2231A flowmeter is calibrated for an inlet pressure of 50 PSIG.

The scale is marked for Argon, Helium, and Argon/CO2 mixes. While it can physically pass straight CO2, the scale readings would not be accurate without a conversion factor.

No, this is a flowmeter only with a 1/4" NPT inlet. It must be attached to a regulator or a pipeline drop that reduces the cylinder pressure to the working pressure (50 PSIG).

The flow tube is made of shatter-resistant polycarbonate (Lexan), which is much more durable than traditional glass tubes.

It features a 1/4" NPT female inlet and a standard 5/8"-18 RH female outlet (CGA 032) for the gas hose.

Yes, the exclusive ball-centering flow tube design allows for accurate readings even if the tube is tipped or not perfectly vertical.

It is covered by the Miller/Smith True Blue 3-Year Warranty.
