14201103 - Tweco 1420-1103 Velocity MIG Liner for 0.023-0.030 Wire

Optimize Your Wire Feed with Tweco Velocity Liners

The Tweco 1420-1103 Velocity MIG Liner is a critical component for professional welders utilizing the Tweco Velocity consumable platform. Engineered specifically for small-diameter welding wires ranging from 0.023" to 0.030" (0.6mm - 0.8mm), this OEM conduit ensures that your wire delivery system operates with minimal friction and maximum consistency. In precision welding applications where small gauge wire is used, even slight resistance in the liner can lead to erratic arc characteristics; this genuine Tweco part eliminates those variables.

Designed to fit Tweco Fusion and Spray Master MIG guns equipped with Velocity front-end consumables, the 1420-1103 liner features a robust coil geometry that resists kinking while maintaining flexibility. This balance is essential for manual welding operations where the gun cable is frequently manipulated around workpieces. By maintaining a concentric path for the wire, the liner prevents shaving and micro-arcing inside the cable, prolonging the life of both the gun and the contact tip.

Regular maintenance of your MIG gun's wire path is vital for quality assurance. A worn or clogged liner is a leading cause of feed issues, often misdiagnosed as drive roll or contact tip failures. Installing a fresh Tweco 1420-1103 liner restores the factory-specified clearance for 0.023"-0.030" wires, ensuring that your parameters at the power source translate accurately to the weld pool. Trust in genuine Tweco parts to maintain the integrity of your high-performance welding equipment.
