KP1996-5B1 - Lincoln Electric KP1996-5B1 Contact Tip 5/64in Unthreaded (10-Pack)

Reliable Arc Stability with Lincoln Electric Contact Tips

Achieve superior welding results with the Lincoln Electric KP1996-5B1 Contact Tip, a vital component for any welder utilizing 5/64-inch (2.0 mm) welding wire. The contact tip is the final point of electrical contact in the MIG gun, and its condition directly influences the stability of the welding arc. Lincoln Electric has engineered the KP1996-5B1 to deliver consistent electrical conductivity and thermal resistance, ensuring that the welding current is transferred smoothly to the wire. This is crucial for preventing voltage drops and maintaining a constant arc length, which are key factors in producing sound, defect-free welds in heavy-duty applications.

The KP1996-5B1 is distinguished by its unthreaded construction and 0.348-inch (8.8 mm) outer diameter. Unlike standard threaded tips that screw into the gas diffuser, this unthreaded variant is designed for specific gun assemblies that utilize a compression or collet-style retention system. This design allows for rapid removal and installation, significantly speeding up the maintenance process during shifts. The 5/64-inch bore is precision-drilled to accommodate 2.0 mm wire with the perfect amount of clearance—tight enough to ensure good electrical contact, but loose enough to allow the wire to feed smoothly without binding, even when the tip heats up and expands during prolonged welding sessions.

Sold in packs of 10, these contact tips are an economical choice for workshops and industrial sites that require reliable consumables on hand. Regular inspection and replacement of contact tips are recommended best practices; a tip that has become oval-shaped or clogged with spatter can cause erratic arc wandering and poor bead appearance. By choosing genuine Lincoln Electric parts like the KP1996-5B1, welders invest in the longevity of their equipment and the quality of their output. These tips are compatible with a range of Lincoln Electric MIG guns designed for heavy wire applications, making them a staple for structural steelworkers, heavy equipment repair technicians, and industrial fabricators.
