0366550882 - ESAB PSF Series Aluminum MIG Liner 0.8mm 3M

Precision Wire Delivery for Aluminum Applications

The ESAB PSF Liner Alum 0.8mm 3M is a specialized component designed to optimize the performance of ESAB PSF series MIG guns when welding with aluminum. Aluminum wire, being significantly softer and more malleable than steel, presents unique challenges in wire feeding systems. Standard steel liners can cause excessive friction, wire shaving, and erratic feeding, leading to arc instability and downtime. This liner addresses these tribological issues through the use of high-grade, low-friction polymer materials that facilitate the smooth passage of 0.8mm aluminum wire over a 3-meter distance.

Engineered to exact tolerances, the internal diameter of this liner is strictly calibrated for 0.8mm wire, preventing the wire from buckling inside the conduit—a phenomenon known as birdnesting. The 3-meter length corresponds to standard torch cable assemblies, ensuring a seamless fit from the wire feeder drive rolls to the contact tip. By maintaining a consistent low-coefficient of friction, the liner minimizes the drag force required by the drive motor, thereby preserving the mechanical integrity of the soft aluminum wire surface. This is critical for preventing the accumulation of aluminum shavings in the liner or at the contact tip, which can cause micro-arcing and burnbacks.

For industrial environments where precision and reliability are paramount, utilizing the correct liner is not merely a recommendation but a necessity for maintaining weld quality. The ESAB PSF Aluminum Liner ensures that the wire feed speed remains constant, directly correlating to stable amperage and voltage output during the welding process. It is an essential consumable for any fabrication setup utilizing ESAB PSF torches for light-gauge aluminum work.
