16401106 - Tweco 64J60 Conductor Tube 60 Degree for No. 4 MIG Gun

Genuine Tweco 64J60 Jacketed Gooseneck for No. 4 MIG Guns

The Tweco 64J60 (SKU: 1640-1106) is a premium OEM replacement conductor tube designed specifically for the industry-standard Tweco No. 4 MIG gun series. Rated for 400 Amps, this heavy-duty gooseneck is engineered to withstand the rigorous demands of industrial welding environments, from structural steel fabrication to heavy equipment manufacturing. As a genuine Tweco part, it ensures optimal electrical conductivity and gas flow, maintaining the high performance your welding operations require.

One of the standout features of the 64J60 is its 60-degree bend angle. This ergonomic design allows welders to access difficult-to-reach joints with greater ease compared to standard 45-degree necks, reducing wrist strain during long shifts. The tube is fully jacketed, meaning it comes with a durable outer insulation layer. This insulation is critical for preventing accidental electrical arcing if the neck contacts the workpiece or fixture, thereby protecting both the equipment and the operator.

Constructed from high-quality copper alloys, the conductor tube excels at heat dissipation, keeping the front-end consumables cooler and extending their service life. It features precision-machined threads for a secure connection to the gun handle and the gas diffuser, ensuring a leak-free gas shield and stable arc transfer. Whether you are replacing a damaged neck or configuring a gun for a specific application, the Tweco 64J60 offers the reliability and fitment that only an OEM part can provide.

Installation is straightforward, fitting seamlessly into existing Tweco No. 4 style handle assemblies. By maintaining your MIG gun with genuine components like the 1640-1106 gooseneck, you ensure consistent wire feeding, reliable current transfer, and minimized downtime in your production line.
