0700300306 - ESAB RT20/RT22F Water Cooled TIG Torch Nozzle

ESAB Replacement Nozzle for Water-Cooled TIG Systems

The ESAB 0700300306 is a specialized nozzle designed for use with the RT20 and RT22F series of water-cooled TIG torches. As a critical component of the gas shielding system, this nozzle directs the flow of inert gas (typically Argon) over the weld pool, protecting it from atmospheric contamination. Manufactured to ESAB's strict OEM specifications, it ensures a tight seal and correct alignment with the torch body, which is essential for maintaining laminar gas flow and preventing turbulence that can lead to porosity.

Technical Compatibility and Construction

This nozzle is engineered to withstand the high thermal loads associated with water-cooled TIG welding applications. While the torch body is actively cooled, the nozzle itself is subjected to intense radiant heat from the arc. The material composition is selected for high thermal shock resistance and electrical insulation properties. It is specifically keyed to fit the collet bodies and gas lenses found in the RT20 and RT22F assemblies, ensuring that the tungsten electrode is properly centered.

Maintenance and Replacement

Regular inspection of TIG nozzles is recommended for industrial maintenance schedules. A damaged or clogged nozzle can disrupt gas coverage, leading to weld defects. The 0700300306 is designed for quick replacement, minimizing downtime in production environments. It serves as a direct replacement part, maintaining the original manufacturer's performance standards for the welding equipment.
