Victor 0781-3508 Inert Gas Welding Regulator 580 Cga

Product Description

The VICTOR 0781-3508 is an inert gas welding regulator designed for use with compressed gas cylinders equipped with a 580 CGA inlet connection. It features a female fitting inlet with right-hand rotation and a maximum inlet pressure rating of 40 psi. The regulator reduces cylinder pressure to a usable delivery pressure for welding and gas-shielding applications. Licensed welders, fabricators, and industrial gas technicians install this type of regulator as part of a shielded welding setup. The unit weighs 1 pound, making it a compact, manageable component for shop or field use.

This regulator is suited for inert gas applications such as MIG and TIG welding where argon, helium, or argon-helium blend cylinders with 580 CGA valve fittings are in use. It is appropriate for both shop bench setups and portable welding rigs. The 580 CGA connection is a standard fitting for non-flammable, non-oxidizing inert gases, making this regulator a common choice in metal fabrication, maintenance welding, and light industrial environments.

Key Features

• 580 CGA inlet connection for compatibility with standard inert gas cylinders
• Female inlet fitting with right-hand rotation
• 40 psi maximum inlet pressure rating
• Compact build at 1 pound
• Designed specifically for inert gas service — not rated for oxygen or fuel gas

Compatibility

Designed for use with inert gas cylinders fitted with a 580 CGA valve connection, including argon and argon-blend cylinders commonly used in MIG and TIG welding applications.

Installation Notes

Installation should be performed by a qualified welder or gas technician familiar with compressed gas equipment. Always close the cylinder valve and bleed residual pressure from the regulator before connecting or disconnecting. Use appropriate thread sealant only where approved for gas service — never use PTFE tape on CGA fittings. Verify the CGA connection type matches the cylinder valve before pressurizing.
