Victor 0781-3584 Acetylene Welding Regulator 510 Cga

Product Description

The VICTOR 0781-3584 is an acetylene welding regulator designed to control and reduce cylinder pressure for safe, consistent delivery to welding torches and downstream equipment. Fitted with a 510 CGA inlet connection and a male fitting, it accepts a 9/16-18 thread engagement at the inlet. The regulator is rated to a maximum outlet pressure of 15 psi, which falls within the standard safe operating range for acetylene gas service. It is installed by licensed welding professionals and skilled trades technicians working with oxy-acetylene cutting, heating, and welding setups.

This regulator is intended for acetylene gas applications in both shop and field environments. The 510 CGA inlet is the industry-standard connection for acetylene cylinders, making this unit a common service replacement or initial-setup component for oxy-acetylene welding stations. It is suited for light-duty to moderate-duty welding and cutting work where reliable pressure control at the cylinder is required.

Key Features

• 510 CGA inlet connection — standard for acetylene cylinder service
• Male inlet fitting with 9/16-18 thread engagement
• 15 psi maximum outlet pressure rating appropriate for acetylene service
• Designed for oxy-acetylene welding, cutting, and heating applications

Compatibility

Designed for use with acetylene cylinders equipped with a 510 CGA valve outlet. Verify inlet thread and downstream equipment compatibility before installation.

Installation Notes

Installation should be performed by a qualified welding professional familiar with compressed gas safety requirements and applicable codes. Close the cylinder valve and bleed all pressure from the regulator before connecting or disconnecting. Do not use thread sealant or PTFE tape on CGA inlet connections — these fittings rely on metal-to-metal seating. Inspect the inlet seat and inlet filter for damage or debris before attaching to the cylinder.
