16401399 - Tweco Velocity VCTLSPR Wave Spring (Pack of 10)

Tweco Velocity VCTLSPR Wave Spring (1640-1399)

The Tweco 1640-1399 (VCTLSPR) Wave Spring is a specialized replacement component engineered for the Tweco Velocity™ MIG welding gun series. This package contains 10 genuine wave springs, essential for maintaining the performance and longevity of the Velocity consumable platform. The Velocity system is distinguished by its threadless, drop-in contact tip design, which relies on precise internal tension to ensure solid electrical connectivity and thermal transfer. The VCTLSPR wave spring provides this critical tension, securing the contact tip and gas diffuser within the conductor tube.

Manufactured from high-quality spring steel, these components are designed to withstand the intense thermal cycling inherent in industrial welding environments. Over time, constant heating and cooling can cause metal fatigue in retention springs, leading to a loss of tension. A loose front-end assembly can result in erratic arcs, poor gas coverage, and increased electrical resistance. By replacing the wave spring during routine maintenance intervals, operators can ensure their Tweco Velocity MIG guns continue to operate at peak efficiency.

This 10-pack configuration is ideal for fabrication shops and industrial facilities that require a steady supply of consumables and spare parts. The springs are compatible with the full range of Velocity-equipped MIG guns, making them a versatile addition to any maintenance inventory. Proper installation of the wave spring ensures that the unique gas-cooling capabilities of the Velocity system are maintained, protecting the contact tip from overheating and extending the life of the entire front-end assembly.

Whether used in automotive manufacturing, heavy equipment fabrication, or general structural steel work, the integrity of the MIG gun's internal components is paramount. The Tweco 1640-1399 wave spring is a small but vital part that safeguards the quality of the weld by stabilizing the consumable stack-up. Trust only genuine Tweco parts to maintain the reliability and performance standards of your ESAB and Tweco welding equipment.
