19759 - Plastic MIG Liner for Aluminum Wire

Optimized Wire Feeding for Aluminum Welding

The ESAB 19759 Plastic Liner is a specialized component designed to enhance the performance of MIG welding operations, particularly when working with soft wires such as aluminum. Unlike traditional steel liners, which can cause friction and shaving on softer filler metals, this plastic liner provides a smooth, low-resistance path for the wire to travel from the feeder to the contact tip. This reduction in friction is critical for preventing feeding issues like bird-nesting and erratic arc stability, ensuring a consistent and high-quality weld bead.

Durable and Flexible Construction

Constructed from high-grade durable plastic materials, often referred to as polymer or Teflon-style liners in the industry, this product offers excellent flexibility and resistance to kinking. The material is specifically chosen to withstand the mechanical stresses of welding environments while maintaining its structural integrity inside the cable assembly. Its smooth interior surface minimizes drag, allowing for longer gun cables to be used with aluminum wire without the typical feeding problems associated with metal liners.

Essential for Soft Alloy Fabrication

For fabricators and welders specializing in aluminum or other soft alloys, switching to a plastic liner is a mandatory step for achieving professional results. Metal liners can contaminate aluminum wire with steel shavings, leading to weld defects and corrosion issues. The 19759 Plastic Liner eliminates this risk, ensuring that the wire remains clean and undeformed as it passes through the torch. It is an indispensable accessory for industries such as automotive repair, boat building, and general aluminum fabrication.
