1000-0255 - Victor FM 135 Heavy Duty Argon/Helium Flowmeter 25 PSIG

Precision Gas Control for Industrial Applications

The Victor FM 135 Heavy Duty Flowmeter (1000-0255) represents the standard for accuracy and durability in shielding gas delivery systems. Designed specifically for industrial environments where precision is paramount, this unit is engineered to monitor and control the flow of Argon and Helium in MIG (GMAW) and TIG (GTAW) welding processes. Unlike standard flowmeters that may fluctuate with back-pressure, the FM 135 is pressure compensated, ensuring that the reading you see on the tube is the actual amount of gas reaching your weld puddle, even when line restrictions or cable lengths vary.

Engineered for Low Surge Performance

One of the critical technical advantages of the FM 135 is its calibration for an inlet pressure of 25 PSIG. In many shop environments, gas surge at the start of a weld can lead to turbulence, porosity, and wasted consumables. By operating at a lower inlet pressure compared to the standard 50 or 80 PSI units, this flowmeter minimizes that initial blast of gas (surge), providing a smoother arc start and significant cost savings on shielding gas over time. It is the ideal choice for shop pipeline systems or for attaching to the low-pressure outlet of a regulator.

Rugged Construction for Severe Duty

Victor has constructed the FM 135 to withstand the rigors of heavy industry. The flow tube and the protective outer cover are manufactured from impact-resistant Lexan, a material renowned for its toughness and clarity. This design choice eliminates the breakage common with glass tubes in busy workshops. Furthermore, the cover tube incorporates an overpressure protection mechanism, adding a layer of safety for the operator. Whether integrated into a piped shop manifold or used as a replacement component on a heavy-duty regulator, the FM 135 delivers consistent, reliable performance.
