KP2095-1 - Lincoln Electric KP2095-1 Liner Spring Guide (.113 ID x .240 OD x 5.94 L)

Precision Wire Guidance with the Lincoln Electric KP2095-1

The Lincoln Electric KP2095-1 Liner Spring is a specialized component engineered to maintain the integrity of the wire feed path in industrial MIG welding systems. Designed with exacting tolerances, this spring features an inner diameter (ID) of 0.113 inches (3 mm) and an outer diameter (OD) of 0.240 inches (6.1 mm). With a total length of 5.94 inches, it serves as a critical interface component, often utilized to bridge the gap between the wire drive rolls and the beginning of the gun liner, or within specific gun connection kits. Its primary function is to support the welding wire as it transitions through the feeder mechanism, preventing the wire from buckling or wandering under the compressive force of the drive rolls.

Manufactured from high-grade spring steel, the KP2095-1 offers the necessary balance of rigidity and flexibility. The material selection ensures that the spring resists deformation over time, even under the constant friction of moving wire. The smooth internal surface finish minimizes drag, which is essential for maintaining consistent arc characteristics and preventing feedability issues such as stuttering or burn-back. As a genuine Lincoln Electric OEM part, this liner spring meets the manufacturer's strict quality standards, ensuring seamless compatibility with the intended Lincoln wire feeders and MIG gun assemblies.

In heavy-duty industrial environments, the condition of the wire drive path is paramount to productivity. A worn or kinked liner spring can lead to shaved wire, accumulation of debris, and ultimately, "birdnesting" at the feeder. Replacing the liner spring with the correct KP2095-1 specification restores the optimal clearance required for the wire size being used. The 0.113-inch ID is sufficiently large to accommodate a variety of standard wire diameters, typically up to 3/32 inch, allowing for versatility across different welding procedures. Maintenance personnel and welding engineers rely on genuine components like the KP2095-1 to ensure equipment reliability and minimize unplanned downtime associated with wire feeding faults.

Proper installation of the KP2095-1 involves ensuring it is seated correctly within the guide adapters. Its precise 5.94-inch length is calculated to fit specific housing dimensions without requiring modification. By maintaining the alignment of the wire from the drive rolls into the gun cable, this component plays a vital, albeit often overlooked, role in achieving high-quality weld deposits. Trusting genuine Lincoln Electric parts for these critical wear points ensures that the welding system operates at its designed efficiency.
