400562-038 - Tweco Replacement Compression Spring 400562-038

Product Overview

The Tweco 400562-038 is a specialized compression spring designed as a direct replacement component for specific Tweco MIG welding gun assemblies. As an Original Equipment Manufacturer (OEM) part, it is engineered to meet the exact dimensional and material specifications required by Tweco equipment, ensuring seamless integration and optimal performance. This spring plays a critical role in the mechanical operation of the welding gun, often utilized within trigger mechanisms, liner retention systems, or connection seating assemblies where consistent axial force is required.

Technical Specifications

Manufactured from high-grade spring steel, this component is heat-treated to resist fatigue and maintain its elastic properties over thousands of compression cycles. The wire diameter, coil pitch, and free length are calibrated to provide the specific force rating needed for its application within the torch body. Using non-OEM springs in precision welding equipment can lead to mechanical binding, insufficient return force, or premature failure due to material incompatibility. The 400562-038 ensures that the internal mechanics of the torch function smoothly, reducing downtime associated with mechanical jams or loose components.

Inventory and Maintenance

For industrial MRO (Maintenance, Repair, and Operations) inventory, stocking the 400562-038 is recommended for facilities utilizing Tweco MIG platforms. Springs are consumable mechanical wear items that can lose tension over time or succumb to environmental factors such as corrosion if exposed to moisture. Regular inspection of the torch assembly during liner changes or contact tip replacement can reveal if the existing spring has become permanently deformed or broken. Immediate replacement with this specific SKU restores the equipment to factory standards.

Compatibility

This part is identified by the internal SKU TWE400562-038. It is essential to cross-reference the welding gun's parts breakdown or service manual to confirm that part number 400562-038 is the correct spring for the specific model of torch or accessory being serviced. Proper installation ensures the longevity of the welding gun and the safety of the operator.
