0781-4236 - Victor AF150-580 Inert Gas Flow Regulator with 10' Hose

Victor AF150-580 Flow Regulator Overview

The Victor AF150-580 Flow Regulator (SKU: 0781-4236) is a precision-engineered gas control device designed specifically for light-duty MIG (GMAW) and TIG (GTAW) welding applications. Part of the renowned G150/AF150 series, this unit is built to manage inert shielding gases such as Argon, Helium, and Argon/CO2 blends. Unlike standard pressure regulators that measure output in PSI, this flow regulator is equipped with a gauge calibrated in Cubic Feet per Hour (CFH), allowing welders to accurately set the shielding gas flow rate required for optimal weld pool protection.

Constructed with a forged brass body and a high-strength alloy bonnet, the AF150 offers superior durability compared to plastic or die-cast alternatives often found in this category. The internal mechanism features a stem-type seat that ensures consistent flow delivery and a reliable seal when closed. The regulator is designed with a CGA 580 inlet connection, the industry standard for inert gas cylinders in North America. Its compact profile makes it an excellent choice for portable welding rigs, HVAC repair kits, and hobbyist workshops where space and weight are considerations.

One of the key technical benefits of this model is the inclusion of a 10-foot gas hose, pre-fitted for immediate use. This integration simplifies setup and ensures compatibility between the regulator and the welding power source. The ergonomic, color-coded adjustment knob provides smooth operation, allowing users to fine-tune flow rates between 0 and 30 CFH (or similar ranges depending on specific calibration) with ease. Whether used for light fabrication or artistic metalwork, the Victor AF150-580 delivers the quality and performance professionals expect from the Victor brand.
