999534 - ESAB 2-Inch Replacement Flow Gauge 0-40 CFH Steel Case

Precision Gas Control with the ESAB 0-40 CFH Flow Gauge

Every welder knows that shielding gas is the lifeblood of a quality MIG or TIG weld. Too little gas leads to porosity and oxidation; too much gas creates turbulence that pulls in atmospheric contaminants and wastes money. The ESAB 999534 Flow Gauge is your solution for dialing in that perfect flow rate. Designed to replace broken or worn-out gauges on your regulator, this unit provides a clear, accurate reading from 0 to 40 Cubic Feet per Hour (CFH), covering the sweet spot for almost all standard welding applications.

Built for the Shop Floor

Accidents happen. Regulators get knocked over, cylinders tip, and tools get dropped. That’s why this ESAB gauge features a rugged steel case. Unlike cheap plastic gauges that crack at the first sign of impact, the steel housing of the 999534 protects the sensitive internal movement mechanism, ensuring that your readings remain accurate over time. The 2-inch dial is large enough to read from a distance but compact enough to stay out of the way.

Easy to Read, Easy to Install

The gauge features a distinctive blue face that offers excellent contrast against the white markings. This makes it incredibly easy to check your flow rate with a quick glance under a welding hood or in a dimly lit shop corner. The Lower Back Mount (LBM) design threads directly into the back of your regulator, facing forward for optimal visibility. Whether you are welding carbon steel with CO2 or aluminum with pure Argon, this gauge gives you the feedback you need to maintain a stable arc and a clean puddle.

Why Replace Your Gauge?

A sticking or broken needle isn't just an annoyance; it's a quality risk. If you are guessing your flow rate, you are gambling with your weld quality. Swapping out a damaged gauge is a quick, inexpensive fix that restores your regulator to full functionality. This ESAB unit is compatible with many standard regulators requiring a back-mount flow indicator. Simply apply a little thread tape or paste, screw it in snugly (do not overtighten!), and you are back in business with professional-grade precision.
