KP3543-364116-35 - Lincoln Electric Aluminum MIG Liner .035-1/16 35ft

Reliable Aluminum Wire Feeding with Lincoln Electric

The Lincoln Electric KP3543-364116-35 Liner is a specialized component designed to address the unique challenges of welding with aluminum wire. Unlike steel wire, aluminum is soft and pliable, making it prone to buckling, kinking, and "birdnesting" if subjected to excessive friction within the MIG gun cable. This liner is manufactured from high-quality, low-friction materials that facilitate the smooth transport of aluminum wire from the feeder to the contact tip. With a generous length of 35 feet, this liner is particularly well-suited for setups requiring extended reach, such as push-pull gun systems or long conduit runs often found in industrial fabrication environments.

Compatibility is key when selecting welding consumables, and this liner is engineered to accommodate a specific range of wire diameters. It effectively handles aluminum wire sizes from 0.035 inches up to 1/16 inches (approximately 0.9mm to 1.6mm). This versatility allows welders to switch between common aluminum wire gauges without needing to change the liner, provided the wire falls within this specified range. The internal geometry of the liner supports the wire continuously, reducing the column strength required to push the wire through the gun, which is the primary cause of feeding issues in aluminum welding.

Using genuine Lincoln Electric parts like the KP3543-364116-35 ensures that your equipment operates at peak performance. Aftermarket or incorrect liners can lead to erratic wire feeding, unstable arcs, and increased downtime due to maintenance. This liner is designed to fit seamlessly into compatible Lincoln Electric MIG guns and conduit systems, providing a tight and secure fit that prevents gas loss and maintains the integrity of the shielding gas coverage. Whether you are working in marine fabrication, trailer manufacturing, or general aluminum repair, this liner provides the consistency needed for high-quality welds.

Installation of the liner is straightforward but requires attention to detail. It is essential to trim the liner to the correct length for your specific gun assembly to prevent gaps where the wire could wander. A properly installed liner drastically reduces friction and wear on the wire, preventing the accumulation of aluminum shavings that can clog the liner and contact tip. By investing in the correct liner for your aluminum applications, you ensure smoother operation, longer consumable life, and superior weld results.
