16401336 - Tweco VCTL64SFLX Velocity Flexible Conductor Tube 60 Degree

Technical Overview of the Tweco 1640-1336 Conductor Tube

The Tweco 1640-1336, model VCTL64SFLX, is a specialized conductor tube designed for the Velocity series of MIG welding guns. Manufactured by ESAB under the Tweco brand, this component serves as the critical current-carrying extension between the gun handle and the contact tip. The 'VCTL64SFLX' nomenclature indicates its specific configuration: Velocity series (V), Conductor Tube (CT), Long reach (L), 60-degree bend (6), and Flexible construction (SFLX).

This unit is engineered to provide a reliable electrical path while offering mechanical adaptability. The flexible body allows the operator to manually adjust the curvature of the neck, deviating from the standard 60-degree pre-set to accommodate complex joint geometries. This flexibility is achieved through a specialized braided copper and elastomer construction that retains rigidity during welding but yields to deliberate adjustment force. It is fully compatible with Tweco Velocity consumables, ensuring a seamless fit with Velocity gas nozzles and contact tips. The tube is designed for air-cooled operation and maintains thermal stability under standard duty cycles associated with manual MIG welding.

Installation requires proper seating into the MIG gun handle to ensure maximum conductivity and gas seal. The internal bore is finished to minimize friction, facilitating smooth wire feeding for solid and flux-cored wires. As a genuine OEM part, it ensures compliance with the original performance specifications of Tweco Velocity MIG guns.
