OVERVIEW

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.

FAQ

This liner is designed specifically for wire diameters of 0.023 inches to 0.030 inches (0.6mm to 0.8mm).

Yes, this is a genuine Tweco OEM part, ensuring perfect compatibility with your Tweco equipment.

It is compatible with Tweco MIG guns that use the Velocity consumable system, such as the Tweco Fusion and Spray Master series.

Liners should be changed when you experience erratic wire feeding, or regularly during preventative maintenance, especially if the gun is used daily in dirty environments.

No, this is a steel wound liner intended for hard wires (steel, stainless). For aluminum wire, you typically require a Teflon or polymer liner to prevent friction and shaving.

Yes, most replacement liners come longer than necessary to fit various cable lengths. You will need to trim it to the correct length for your specific gun cable assembly according to the manufacturer's instructions.

Using a liner with an internal diameter that is too large for the wire (e.g., running 0.023 wire in a 0.045 liner) can cause the wire to wander inside the liner, leading to poor electrical pickup and an unstable arc.

The Tweco Velocity system integrates the gas diffuser, contact tip, and nozzle in a way that improves conductivity and gas coverage. The liner is a key part of this system, ensuring smooth delivery to the contact tip.
