1000-0263 - Victor FM157 Argon/Helium Flowmeter Assembly, 1/4" NPT Inlet

Precision Shielding Gas Control with Victor FM157

Achieve optimal weld quality with the Victor FM157 Argon/Helium Flowmeter, a reliable solution for managing shielding gas delivery in professional welding operations. Shielding gas flow is a critical variable in the welding process; too little flow leads to porosity and oxidation, while too much causes turbulence and waste. The FM157 (1000-0263) provides the visual feedback and precise control necessary to dial in the perfect flow rate for your specific application.

Designed for the rigors of the industrial environment, the FM157 sets itself apart with its impact-resistant Lexan construction. In many workshops, glass flow tubes are a frequent casualty of rough handling or accidental impact. Victor has addressed this by utilizing high-strength Lexan for both the inner flow tube and the protective outer cover. This ensures that the gauge remains readable and intact even under severe conditions, providing long-term reliability for structural steel fabrication, repair, and maintenance tasks.

This flowmeter is a "medium duty" unit ideal for both MIG and TIG applications. It features a clear, easy-to-read scale calibrated for two of the most common inert gases: Argon and Helium. The Argon scale reads from 15 to 65 SCFH, covering the vast majority of steel and stainless steel welding procedures. The Helium scale extends from 40 to 200 SCFH, accommodating the higher flow rates often required for aluminum welding or specialized mixtures. The unit is pressure compensated at 25 PSIG, ensuring that the ball float provides a true reading of the gas volume being delivered to the weld puddle.

The assembly comes ready to mount with a 1/4-inch NPT male inlet, making it suitable for attachment to shop pipeline drops or as a replacement component for existing regulator assemblies. The outlet accepts standard inert gas hose nuts (CGA 032 / 5/8"-18 RH). Whether you are setting up a new welding station or upgrading your gas distribution system, the Victor FM157 delivers the accuracy and toughness demanded by professional welders.
