The Lincoln Electric KP1958-1B1 is a specialized MIG gun liner designed explicitly for the transport of aluminum welding wire. Unlike standard steel liners which use a wound steel spring construction, this liner utilizes a high-grade polymer material. This material selection is critical for aluminum applications because aluminum wire is significantly softer and more susceptible to surface damage than steel wire. A steel liner would act as an abrasive against the soft aluminum surface, causing shavings to accumulate within the conduit. These shavings eventually clog the liner, leading to erratic feeding, micro-arcing within the contact tip, and potential burnback. The KP1958-1B1's smooth polymer interior minimizes this friction coefficient, ensuring the wire glides effortlessly from the drive rolls to the contact tip.
This specific liner is sized for wire diameters ranging from .035 inches to 3/64 inches (approximately 0.9 mm to 1.2 mm), covering the most common gauges used in light to medium-duty aluminum fabrication. The liner is color-coded Black, adhering to Lincoln Electric's identification system, which allows shop managers and technicians to visually verify that the correct liner is installed for the wire being used. The liner measures 10 feet (3 meters) in length, making it compatible with standard 10-foot MIG gun cable assemblies. For shorter guns, the liner can be trimmed to size using standard liner trimming tools, ensuring a precise fit against the gas diffuser or retaining head.
Supplied in a pack of 10, this SKU is intended for industrial environments where preventative maintenance is key to uptime. Aluminum liners are considered consumables and should be replaced regularly to prevent contamination and feed issues. Over time, even polymer liners can accumulate aluminum oxide dust or become kinked. Having a bulk pack ensures that maintenance personnel can swap out liners immediately upon detecting feed resistance, maintaining the integrity of the welding process. This product is compatible with various Lincoln Electric MIG guns, including the Magnum and Magnum PRO series, provided they are configured for 10-foot cable lengths.
