0781-4226 - Victor GF150 Series Light Duty Argon Flowgauge Regulator CGA-580

Precision Control for Light Duty Applications

The Victor GF150-50-580 Argon Flowgauge Regulator (SKU: 0781-4226) is a premium gas control device engineered for professionals and serious hobbyists requiring reliable shielding gas delivery. Part of the renowned G150 series, this regulator is specifically designed to replace the legacy SR6 and SR160 series, offering updated ergonomics and material improvements. It is constructed with a solid brass body and a high-strength alloy bonnet, ensuring resilience against the rigors of light fabrication environments and HVAC service calls.

This single-stage cylinder regulator features a CGA 580 inlet connection, making it compatible with standard Argon and Argon-mix cylinders used in MIG and TIG welding. The unit provides a delivery range of 0-50 SCFH (0-25 LPM), which is optimal for shielding gas coverage in light-to-medium gauge welding tasks. The internal mechanism is designed to handle a maximum inlet pressure of 3,000 PSIG, providing a wide safety margin for standard industrial gas cylinders.

Distinctive to the GF150 model is its use of a flowgauge mechanism rather than a floating-ball flowmeter. This design utilizes a calibrated pressure gauge to indicate flow rate, which is often preferred in portable applications where the cylinder may not always be perfectly vertical. The dual 1.5-inch gauges feature high-contrast faces, allowing operators to quickly verify cylinder pressure and output flow at a glance. The pressure adjusting knob is color-coded and ergonomically shaped, facilitating smooth adjustments even when wearing work gloves.

Safety and compliance are paramount in the design of the GF150-50-580. It is UL Listed and backed by Victor's 7-Year Limited Warranty, reflecting the manufacturer's confidence in its build quality. Whether for maintenance, repair, or artistic fabrication, this regulator delivers the consistent flow characteristics necessary for high-quality weld beads.
