13401132 - Tweco Velocity Slip-On Nozzle Insulator / Tip Adapter (2-Pack)

Tweco Velocity VNSS-INS Nozzle Insulator (1340-1132)

The Tweco Velocity VNSS-INS Nozzle Insulator, also referenced by part number 1340-1132, is a critical component for the Velocity and Velocity2 series of MIG welding guns. Designed to function as both an insulator and a tip adapter, this component enables the unique slip-on functionality that defines the Velocity consumable system. Unlike traditional threaded systems that can seize or require pliers for removal, the VNSS-INS allows the nozzle to slide securely into place, held by friction and precision engineering, ensuring a tight seal for shielding gas while maintaining electrical isolation from the contact tip.

This package contains two (2) light-duty insulators, specifically engineered for standard fabrication environments where ease of maintenance and downtime reduction are priorities. The insulator seats directly onto the conductor tube, providing a thermal and electrical barrier. By utilizing the Velocity system's streamlined design, operators can replace contact tips and nozzles without the use of tools, significantly speeding up the process of clearing bird-nests or replacing worn parts. The VNSS-INS is compatible with Velocity contact tips and slip-on nozzles, forming an integrated front-end solution that optimizes arc stability.

Manufactured by ESAB under the Tweco brand, these insulators are built to withstand the thermal cycling inherent in MIG welding. However, as a consumable item, they will eventually degrade over time due to heat exposure and spatter accumulation. Replacing the insulator regularly is essential to prevent arc wandering, gas turbulence, or accidental arcing to the nozzle. This 2-pack ensures you have a spare on hand to keep production running smoothly. The component is identified as a "Light Duty" adapter, making it ideal for lower amperage applications where maneuverability and compact torch head size are beneficial.

Technical specifications include a direct fit for Velocity-equipped guns and compatibility with the VNSS series of nozzles. The insulator's geometry is designed to smooth out gas flow as it exits the diffuser area, contributing to better weld pool protection and reduced porosity. Whether upgrading an existing setup or restocking a tool crib, the Tweco 1340-1132 is the genuine OEM part required to maintain the performance standards of your Velocity MIG gun.
