The Lincoln Electric KP2086-1B1 is a specialized contact tip designed for industrial MIG and flux-cored welding applications requiring a .068 inch (1.7 mm) wire diameter. Engineered to precise OEM tolerances, this contact tip ensures consistent electrical contact between the power source and the welding wire, which is critical for maintaining a stable arc and achieving high-quality weld deposition. The tip features a specific 18-thread pattern, allowing for a secure mechanical and electrical connection to the gas diffuser or gun tube, minimizing resistance and heat buildup at the joint.
With a length of 5/16 inch (7.9 mm), this component is designed for specific torch geometries where tip recess or stick-out must be carefully managed. The internal bore is machined to accommodate .068 inch wire with appropriate clearance to prevent binding while maximizing surface contact for current transfer. Improper tip sizing can lead to erratic arcs, burn-backs, or excessive spatter; therefore, utilizing the correct KP2086-1B1 tip is essential for procedures qualified for this wire size. These tips are supplied in packs of 10, facilitating routine maintenance schedules in high-volume production environments.
Material composition and machining quality are hallmarks of Lincoln Electric consumables. The copper alloy used in the KP2086-1B1 provides excellent thermal conductivity, helping to dissipate heat generated during the welding process. This thermal management helps resist keyholing (the wearing of the bore into an oval shape) and premature failure, ensuring that the tool center point (TCP) remains consistent for automated or manual operations.
