4403503410 - Fronius MTG 320i Combination MIG Liner .045" (16.4 ft)

Genuine Fronius MTG 320i Combination Liner (.045")

Maximize the performance and versatility of your welding operations with the Fronius MTG 320i MIG Gun Combination Liner. Identified by part number 44,0350,3410, this premium replacement component is engineered specifically for the Fronius MTG 320i series of MIG torches. It is designed to handle the rigorous demands of industrial welding while providing exceptional wire feeding consistency.

The standout feature of this liner is its "combination" design. Unlike standard steel liners that can damage soft aluminum wires, or polymer liners that may wear quickly with steel, this combination liner is constructed to bridge the gap. It is fully compatible with both Mild Steel and Aluminum Welding Wire. This dual compatibility makes it an invaluable asset for workshops that frequently switch between base materials, reducing the downtime associated with swapping out torch consumables.

Sized for .045" (1.2mm) wire, this liner ensures a tight tolerance that prevents wire buckling inside the cable, a common cause of erratic arcs and bird-nesting. The liner comes in a length of 16.4 feet (approx. 5 meters), providing ample reach for standard torch packages. Whether you are fabricating aluminum structures or welding mild steel components, this genuine Fronius part ensures that your wire is delivered to the contact tip with minimal friction and drag.

Regular maintenance of your MIG gun's liner is critical for weld quality. A clogged or kinked liner can lead to burn-back and unstable arcs. By choosing genuine Fronius parts from Josef Gas, you ensure that your equipment operates at peak efficiency, maintaining the high standards expected from Fronius welding systems.
