3100405 - Harris Model 725 Heated Two-Stage Flow Meter Regulator CGA 580

Reliable Flow in Any Condition

For professional welders and fabricators, consistency is key. The Harris Model 725 Heated Flow Meter Regulator (SKU: 3100405) is built to ensure your shielding or purging gas flow never falters, even under the most demanding conditions. Standard regulators can struggle during long, high-flow operations; as the gas expands rapidly, temperatures drop, potentially causing the regulator to freeze up and shut down your line. This Harris unit solves that problem with a built-in 120-volt, 200-watt heater. By actively warming the gas passage, it prevents the formation of ice and frost, allowing you to run high flow rates of Argon, Nitrogen, or Helium without interruption.

Beyond its heating capabilities, this is a true two-stage regulator. If you have ever had to constantly adjust your flow meter as your tank gets low, you know the frustration of single-stage drift. The two-stage design of the Harris 725 automatically compensates for dropping cylinder pressure, delivering a flat, consistent flow rate from the moment you crack the valve until the tank is empty. This means less time fiddling with knobs and more time focused on your weld or fabrication task.

Durability is standard with Harris equipment. The 3100405 features a heavy-duty chrome-plated brass body that stands up to shop abuse and resists corrosion. It connects easily to any standard CGA 580 cylinder and provides adjustable flow control up to 100 SCFH. Whether you are purging piping systems with Nitrogen or running heavy automated TIG setups with Argon, this heated regulator provides the
