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

Stop Fighting Your Wire Feed – Upgrade to Tweco Velocity

Is your wire stuttering, slipping, or bird-nesting at the drive rolls? Before you blame the machine, check your liner. The Tweco 1420-1103 Velocity MIG Liner is the direct replacement conduit for welders running 0.023" to 0.030" wire in Tweco Velocity-equipped guns. Over time, liners get clogged with shop dust, metal shavings, and lubricant, creating drag that ruins your weld bead. Swapping out an old liner is one of the cheapest and most effective ways to make your welder run like new again.

This isn't just a generic coil; it's a genuine Tweco OEM part designed for the Velocity system found on Fusion and Spray Master guns. It is built to handle the rigors of the shop floor while providing a smooth, low-friction path for thinner wires. Small diameter wires like 0.023" are particularly prone to buckling if the liner adds too much friction. The 1420-1103 is engineered with the correct internal tolerance to support these wires, preventing the dreaded "accordion" effect inside your cable.

Don't let a $20 part cost you hours of downtime. Keep a spare Tweco 1420-1103 in your toolbox. Whether you are doing auto body work with 0.023" wire or light fabrication with 0.030", this liner ensures your wire makes it from the feeder to the puddle without a hitch. Get the reliability you expect from Tweco and keep your arcs smooth and stable.
