Lincoln Electric 3000764 Oxygen Welding Regulator Cga 346

Product Description

The LINCOLN ELECTRIC 3000764 is an oxygen welding regulator designed to reduce and control high-pressure oxygen from a supply cylinder to a usable working pressure. It accepts a maximum inlet pressure of 3000 psi and delivers a maximum outlet pressure of 200 psi through a CGA 346 inlet connection. This regulator is a standard component in oxy-fuel cutting and welding setups, providing stable oxygen flow control throughout the work cycle. Licensed welders, pipefitters, and metalworking professionals install this type of regulator as part of a properly configured gas supply system.

The 3000764 is suited for oxy-fuel welding and cutting applications in fabrication shops, field pipe work, and maintenance environments. It is intended for use with oxygen cylinders fitted with a CGA 346 valve outlet. The CGA 346 connection is standard on certain low-pressure oxygen cylinder configurations. This regulator handles the pressure demands of both light-duty shop work and more intensive cutting operations where consistent oxygen delivery is critical to weld quality and cut performance.

Key Features

• Rated for maximum inlet pressure of 3000 psi, compatible with high-pressure oxygen cylinders
• Maximum outlet pressure of 200 psi for precise working pressure control
• CGA 346 inlet connection for direct cylinder attachment without adapters
• Compact form factor at approximately 7.75 inches tall and 7.5 inches wide
• Single-unit packaging with a minimum order quantity of one

Compatibility

Designed for use with oxygen supply cylinders equipped with a CGA 346 valve outlet. Verify cylinder valve fitting before installation. This regulator is intended for oxygen service only and must not be used with any other gas type.

Installation Notes

Installation should be performed by a qualified welder or gas systems technician familiar with compressed gas safety practices. Always fully close the cylinder valve and bleed downstream pressure before connecting or disconnecting the regulator. Use an appropriate CGA 346 wrench; do not use pipe thread sealants, oils, or grease on oxygen fittings, as these create a serious fire and explosion hazard. Follow all applicable local codes and Compressed Gas Association guidelines for oxygen regulator installation and use.
