16401112 - Tweco Flexible Gooseneck 60 Degree for 300A/400A MIG Guns

Tweco 1640-1112 Flexible Conductor Tube for #3 & #4 MIG Guns

The Tweco 1640-1112 Flexible Conductor Tube is an essential accessory for professional welders who require versatility and precision in their MIG welding operations. Designed specifically for use with Tweco #3 (300 Amp) and #4 (400 Amp) MIG guns, this conductor tube—often referred to as a gooseneck—features a unique flexible design that sets it apart from standard rigid tubes. While it comes with a standard 60-degree bend, the flexible body allows operators to manipulate the neck angle slightly to navigate around obstacles, reach into deep corners, or weld in ergonomically challenging positions without forcing the gun into an awkward stance.

Manufactured by Tweco, a leader in welding gun technology, this part ensures that electrical conductivity and gas flow remain consistent, even when the tube is flexed. The internal liner path is engineered to prevent wire binding, a common issue with inferior flexible necks. This ensures that your wire feed remains smooth and the arc stable, regardless of the position. The outer jacket is made from durable, heat-resistant material that withstands the harsh environment of industrial welding, protecting the internal components from spatter and radiant heat.

Replacing your conductor tube is a routine maintenance task that can significantly improve gun performance. If your current tube is damaged, clogged, or simply too rigid for a specific project, the 1640-1112 offers a robust solution. It installs easily into compatible Tweco handle assemblies, restoring your equipment to peak functionality. Whether you are working in automotive repair, structural steel fabrication, or general maintenance, having a flexible conductor tube in your toolkit expands your welding capabilities and improves operator comfort.

At Josef Gas, we understand the importance of reliable equipment. This genuine Tweco part guarantees fitment and performance, ensuring that your downtime is minimized and your weld quality remains high. Upgrade your Tweco MIG gun with this versatile flexible conductor tube and experience the difference in accessibility and control.
