0781-3819 - Victor HSR 2530 Medium Duty Flow Meter Regulator, Nitrogen/Air, CGA 580

Reliable Shielding and Purging Gas Delivery

For professional welders and fabricators, consistent gas flow is critical to achieving high-quality welds. The Victor 0781-3819 HSR 2530-580 Flow Meter Regulator provides the precision and reliability needed for demanding shop environments. While often used for Nitrogen and Air, this regulator is particularly valuable for back-purging stainless steel pipes or tanks during TIG welding, where maintaining a stable, oxygen-free atmosphere is essential to prevent oxidation and "sugaring" on the root pass.

Designed for Efficiency and Economy

Gas waste is a common hidden cost in welding operations. Traditional regulators can allow a large burst of gas—known as a surge—every time the torch trigger is pulled or a valve is opened. The Victor HSR 2530 series addresses this with a preset outlet pressure of 25 PSIG, engineered to keep surge rates low. This feature ensures that you use only the gas you need, extending the life of your cylinders and reducing the frequency of change-outs. The flow tube provides a visual confirmation of the flow rate (10-60 SCFH), allowing welders to dial in the exact settings required for their specific procedure specification (WPS).

Victor Quality You Can Trust

Victor has been a household name in the welding industry for decades, known for producing equipment that lasts. This regulator/flowmeter combination lives up to that reputation with a rugged forged brass body that stands up to accidental bumps and knocks in a busy workshop. The internal components are equally tough, featuring a fabric-reinforced neoprene diaphragm that maintains accuracy over thousands of cycles. The stem-type seat mechanism is designed for reliable sealing, reducing the risk of creep or leaks that could compromise your gas supply.

Ready for the Job Site

Whether you are setting up a stationary bench for component fabrication or outfitting a mobile rig, the compact size of the HSR 2530-580 is a major advantage. It fits neatly within the cylinder profile, reducing the snag hazard during transport. The clear, 2-inch gauge allows for quick checks of remaining cylinder pressure, ensuring you never run dry in the middle of a critical weld. With its standard CGA 580 connection, it hooks up quickly to Nitrogen cylinders, getting you ready to work with minimal downtime. Invest in a regulator that delivers both performance and peace of mind.
