16401122 - Tweco Flexible Gooseneck 80 Degree for #3 and #4 MIG Guns

High-Performance Flexible Conductor Tube for Precision Welding

The Tweco 1640-1122 Flexible Conductor Tube is a specialized replacement component designed for Tweco #3 and #4 series MIG guns. Engineered for industrial environments where accessibility is a challenge, this conductor tube features a flexible body capable of achieving an 80-degree bend. This flexibility allows operators to manipulate the torch angle significantly beyond the limitations of standard rigid goosenecks, ensuring optimal electrode positioning in restricted spaces.

Constructed from high-grade copper alloys, the tube maintains excellent electrical conductivity and thermal dissipation properties, essential for maintaining arc stability during prolonged welding sessions. The outer jacket is manufactured from heat-resistant, durable silicone rubber that withstands the harsh conditions of welding environments, including exposure to heat, spatter, and abrasion. This ensures a long service life and reliable performance under duty cycles typical of 300A and 400A applications.

Installation is straightforward, utilizing the standard threaded connections found on Tweco Spray Master and similar series guns. This part is critical for fabrication shops dealing with complex assemblies, pipe welding, or automotive repair where standard torch angles fail to provide adequate visibility or gas coverage. By integrating the 1640-1122 into your equipment inventory, you ensure that your welding team has the adaptability required to handle non-standard joint configurations efficiently.

Technical Specifications

The unit is rated for use with air-cooled MIG guns in the #3 (300 Amp) and #4 (400 Amp) classes. It is designed to replace standard rigid tubes when specific application requirements dictate a non-standard approach angle. The flexibility does not compromise the gas flow laminar characteristics, ensuring that shielding gas coverage remains consistent even when the tube is flexed to its maximum 80-degree angle.
