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

Tweco Flexible Gooseneck 60 Degree – Part 1640-1112

Maximize the versatility of your welding setup with the Tweco 1640-1112 Flexible Conductor Tube. Engineered for the demanding requirements of professional fabrication, this replacement gooseneck is compatible with the industry-standard Tweco #3 and #4 series MIG guns. The defining feature of this component is its flexible body construction, which allows the welder to bend and shape the neck to access hard-to-reach joints that a standard rigid 60-degree tube simply cannot access. This flexibility is invaluable in complex assemblies, pipe welding, and repair work where line-of-sight and gun angle are critical for a sound weld.

Despite its flexibility, the 1640-1112 does not compromise on durability or performance. It is built to handle the amperage ratings of #3 (300A) and #4 (400A) guns, providing excellent thermal management and electrical transfer. The tube features a heavy-duty outer insulation that protects against shorts when working in tight quarters where the nozzle might inadvertently contact the workpiece. Inside, the geometry is designed to support the liner and welding wire, minimizing friction and drag to prevent bird-nesting or erratic feeding, which are critical concerns when deviating from a straight path.

Installation is straightforward, utilizing the standard connection points found on Tweco Spray Master and similar series guns. This allows for quick changeovers on the shop floor. By swapping a rigid neck for this flexible option, welders can reduce wrist strain and fatigue, as the gun can be positioned more naturally while the neck does the work of angling into the joint. It is an ideal solution for maintenance and repair operations (MRO) where every job presents a new geometric challenge.

Invest in genuine Tweco parts to ensure longevity and safety. The 1640-1112 is a testament to Tweco's commitment to ergonomic and functional design. Keep your operations running smoothly and your welds defect-free by ensuring your MIG gun is equipped with the right conductor tube for the job. This part is sold individually and is a must-have spare for any serious fabrication shop utilizing Tweco equipment.
