1000-0258 - Victor FM 370 Professional Station Flowmeter - Argon, CO2, Helium

Precision Gas Control for Professional Welders

When it comes to MIG and TIG welding, consistent gas flow is the invisible variable that can make or break your weld quality. The Victor FM 370 Flowmeter is built to give you that consistency in a package that can survive the daily grind of a fabrication shop. Unlike fragile glass flowmeters that crack the moment something bumps into them, the FM 370 uses a high-strength Lexan flow tube. This impact-resistant material ensures that your flowmeter stays intact and legible, even in busy shop environments where tools and parts are constantly moving around.

This flowmeter is designed for shop pipeline systems—meaning if you have a central gas supply piped to your station, this is the gauge you need to regulate exactly how much gas hits your puddle. It is calibrated for the three big gases: Argon, CO2, and Helium. Whether you are welding aluminum with pure Argon, mild steel with a CO2 mix, or using a Helium blend for extra heat input, this single unit has the scales you need. You won't have to swap out flowmeters just because you changed your base material or process. The scales are easy to read, allowing you to dial in your SCFH (Standard Cubic Feet per Hour) precisely, reducing gas waste and preventing porosity caused by inadequate coverage.

One of the standout features for the welder is the back-pressure compensation. In the real world, your torch cable gets twisted, or spatter builds up in your nozzle. On cheaper gauges, this resistance can give you a false reading, making you think you have flow when you don't. The Victor FM 370 compensates for this, showing you the true flow rate so you can trust your settings. It connects easily to standard gas hoses with its 5/8"-18 RH outlet, making installation a breeze. Upgrade your station drop with a flowmeter that matches the quality of your welding skills.
