OVERVIEW

Take Control of Your Shielding Gas

Achieving the perfect weld requires more than just a steady hand; it requires consistent and precise shielding gas coverage. The Victor FM 371 Flowmeter (1000-0259) is built to give welders exactly that. Whether you are working with Argon, CO2, or Helium, this heavy-duty flowmeter allows you to dial in your flow rates with confidence. Designed for MIG and TIG applications, it helps prevent porosity and oxidation by ensuring your weld pool is always properly protected, without wasting expensive gas through excessive flow.

Built Tough for the Shop Floor

We know that welding environments can be tough on equipment. That is why the Victor FM 371 ditches fragile glass tubes in favor of impact-resistant Lexan. This durable material can take a beating and keep on working, making it an ideal choice for busy fabrication shops, manufacturing plants, and field sites. You don't have to worry about a tipped cart or a stray tool shattering your flowmeter. Plus, the clear, easy-to-read scale makes checking your gas levels a breeze, even from a distance.

Consistent Flow, Better Welds

One of the biggest headaches in welding is gas surge—that initial blast of gas when you pull the trigger. The FM 371 is pressure compensated and calibrated for 25 PSIG inlet pressure to minimize this surge, giving you a smooth, consistent start every time. This feature not only improves the quality of your starts but also saves you money on gas in the long run. The back-pressure compensation means that even if your hose gets a kink or you are using a long lead, the gauge tells you the truth about how much gas is actually reaching your torch.

Easy to Install and Use

Upgrading your setup is simple with the FM 371. It features standard 5/8"-18 fittings, making it compatible with most standard regulators and hose connections. Whether you are replacing a broken gauge or upgrading a regulator to a flowmeter setup, this unit screws right in. It covers a wide flow range—up to 50 SCFH for Argon and CO2, and up to 150 SCFH for Helium—giving you the flexibility to tackle everything from thin sheet metal to heavy structural plate.

FAQ

The FM 371 is calibrated for use with Argon, Carbon Dioxide (CO2), and Helium.

This flowmeter is calibrated to operate at an inlet pressure of 25 PSIG.

No, this is a flowmeter assembly, not a pressure regulator. It must be used downstream of a regulator that reduces the cylinder pressure to approximately 25 PSIG.

The inlet is a 5/8"-18 RH Male connection, and the outlet is a 5/8"-18 RH Female connection.

The flow tube and outer cover are made of impact-resistant Lexan (polycarbonate) for superior durability in industrial environments.

The flow range for Argon is 5 to 50 SCFH (Standard Cubic Feet per Hour).

Yes, the Victor FM 371 is back-pressure compensated, ensuring accurate flow readings even if there are restrictions in the delivery line.

Yes, it is calibrated for Helium with a flow range of 20 to 150 SCFH, making it suitable for TIG welding applications requiring Helium.
