Victor 0781-3507 Inert Gas Welding Regulator 580 Cga

Product Description

The VICTOR 0781-3507 is an inert gas welding regulator designed to control and deliver inert shielding gases from a cylinder to a welding torch or gas distribution system. Built with a 580 CGA inlet connection and a maximum outlet pressure of 15 psi, it provides stable, repeatable pressure regulation across common inert gas welding applications. The 5/8-18 thread inlet ensures a secure, leak-resistant connection to compatible gas cylinders. Licensed welders, pipefitters, and welding supply technicians are the primary installers and service personnel for this type of regulator.

This regulator is suited for use with inert gases such as argon and similar non-reactive shielding gases commonly used in TIG and MIG welding processes. It is appropriate for light industrial and professional shop environments where precise, low-pressure inert gas delivery is required. The 580 CGA inlet is the standard connection for argon and argon-mix cylinders, making this regulator a direct-fit choice for those cylinder types in welding setups.

Key Features

• 580 CGA inlet connection — standard for argon and inert gas cylinders
• 15 psi maximum outlet pressure for controlled, low-pressure delivery
• 5/8-18 inlet thread for secure cylinder attachment
• Designed specifically for inert shielding gas service
• Compact, single-unit package — MOQ of 1

Compatibility

Compatible with cylinders fitted with a 580 CGA valve outlet, the standard connection for argon and inert gas cylinders used in welding applications.

Installation Notes

Installation should be performed by a qualified welder or gas equipment technician familiar with compressed gas regulator service. Always close the cylinder valve and bleed residual pressure from the regulator before connecting or disconnecting. Do not use pipe thread sealant or PTFE tape on CGA inlet connections — these fittings rely on metal-to-metal or nylon seat seals. Follow applicable compressed gas safety standards and shop safety procedures during installation and leak testing.
