0700300320 - ESAB PTFE Liner 1.0-1.2mm 3.5m (5-Pack)

Smooth Feeding for Aluminum MIG Welding

Struggling with bird-nesting and erratic wire feeding when welding aluminum? The solution often lies in your liner. The ESAB PTFE Liner is engineered to solve the common headaches associated with pushing soft aluminum wires through a MIG torch. Made from durable Teflon (PTFE), this liner creates a slick, low-friction path for your wire, allowing it to glide smoothly from the drive rolls to the contact tip.

This specific liner is sized perfectly for 1.0mm to 1.2mm wires, the most common sizes for structural aluminum work. At 3.5 meters long, it fits many standard MIG guns and can be trimmed to fit shorter cables if necessary. Using a steel liner for aluminum is a recipe for disaster—it causes drag and contaminates your weld with steel particles. Switching to this dedicated PTFE liner improves arc stability and weld quality instantly.

We know that in a busy shop, consumables get used up fast. That's why this item comes in a value-packed set of 5. Keep your welding cart stocked and your downtime low. Whether you are welding boat hulls, trailers, or custom aluminum parts, trust ESAB's quality components to keep your machine running at its best.
