23-50-580 - Miller Smith Dual Flowmeter Regulator CGA 580 Argon/CO2/Helium

Precision Gas Control for Advanced Welding Applications

The Miller Dual Flowmeter Regulator (SKU: 23-50-580), formerly known under the Smith Equipment brand, represents the gold standard in gas regulation for professional fabricators. Designed specifically for TIG (GTAW) and MIG (GMAW) applications requiring simultaneous shielding and purging, this unit streamlines operations by allowing two separate gas lines to be managed from a single cylinder source. This capability is critical for sanitary stainless steel piping and other metallurgical applications where back-purging is mandatory to prevent oxidation.

Engineering Excellence

At the core of this regulator is a robust brass body engineered for high-pressure durability. The unit features two independent flowmeters, each equipped with a sensitive needle valve for fine adjustment. Unlike standard regulators, these flow tubes are back-pressure compensated. This means that if there is a restriction downstream—such as a long hose or a gas lens—the flowmeter will still indicate the accurate flow rate, ensuring your weld pool receives the exact coverage required. The delivery pressure is factory-preset at 50 PSIG, optimizing the response time and consistency of the gas flow.

Versatility and Durability

The flow tubes feature a triple-scale design, rotatable for easy reading, calibrated for Argon, Helium, and CO2. This versatility allows the regulator to be used across various welding processes without the need for conversion charts. The tubes are housed in shatter-resistant Lexan polycarbonate covers, providing superior protection against the accidental impacts common in industrial environments. Furthermore, the packless O-ring seal design minimizes maintenance points, while a built-in rupture disc adds a layer of safety against high-pressure inlet surges. This regulator is an essential tool for precision fabrication shops demanding reliability and accuracy.
