16401350 - Tweco Spitfire TS64J45 MIG Gun Conductor Tube 45 Degree

Genuine Tweco Replacement Neck for Spitfire MIG Guns

Keep your welding operations running smoothly with the Tweco 1640-1350 Conductor Tube, the authentic replacement neck for Tweco Spitfire MIG guns. Also known as the model TS64J45, this conductor tube is an essential spare part for any shop utilizing the rugged Spitfire series. Over time, conductor tubes can become damaged from heat cycling, accidental impacts, or thread wear during consumable changes. A compromised conductor tube can lead to poor current transfer, erratic wire feeding, and shielding gas leaks. Replacing a worn neck with this genuine Tweco part restores your gun to factory specifications and ensures consistent weld quality.

Optimized 45-Degree Design
This unit features a 45-degree bend, which is the industry standard for general-purpose welding. This angle provides excellent visibility of the puddle and allows the welder to maintain a natural, comfortable hand position during flat and horizontal welding. It also provides enough offset to reach into tighter spaces without forcing the welder into awkward positions. The tube is designed to work seamlessly with standard Spitfire jump liners and consumables, ensuring that your wire feeds smoothly from the handle to the tip without interruption.

Built for Industry
Tweco's Spitfire line is built for the long haul, and the TS64J45 conductor tube is no exception. Manufactured from heavy-duty materials, it resists bending and deformation better than generic aftermarket alternatives. The high-quality copper construction ensures maximum electrical efficiency, delivering the full power of your machine to the arc. This is particularly important in high-duty cycle applications where resistance heating in the gun can lead to premature failure of components.

Easy Maintenance and Installation
Swapping out your conductor tube is a quick process that minimizes downtime. The Tweco 1640-1350 features precision threads that fit perfectly into your existing Spitfire handle. When installing, simply ensure the mating surfaces are clean and tighten securely to establish a good electrical and gas connection. By keeping a spare TS64J45 on hand, you can prevent minor equipment issues from turning into major production stoppages. Trust in the quality of Tweco to keep your welders welding.
