KP2928-1 - Lincoln Electric KP2928-1 SAW Contact Nozzle 5/32 Inch

Precision Engineering for Heavy-Duty Welding

The Lincoln Electric KP2928-1 Contact Nozzle is a specialized consumable component designed to meet the rigorous demands of industrial welding environments. Engineered specifically for use with 5/32 inch (4.0 mm) diameter welding wires, this contact nozzle plays a critical role in the electrical transfer efficiency of your welding system. In high-deposition processes such as Submerged Arc Welding (SAW) or heavy-duty flux-cored applications, the integrity of the contact point between the power source and the consumable wire is paramount. The KP2928-1 is manufactured to strict tolerances, ensuring that the internal bore maintains optimal contact with the wire without causing excessive drag or feeding issues.

Constructed from high-grade copper alloy, this nozzle is formulated to withstand the intense heat generated during prolonged welding cycles. Thermal conductivity is a key factor in the performance of contact nozzles; poor heat dissipation can lead to premature softening of the tip, keyholing, and erratic arc characteristics. Lincoln Electric's material selection ensures that the KP2928-1 maintains its structural integrity even under high amperage loads, providing a stable current transfer that results in consistent weld bead profiles and reduced spatter.

Reliability is the cornerstone of the Lincoln Electric brand. By utilizing genuine OEM parts like the KP2928-1, operators can trust in the compatibility and performance of their equipment. This nozzle is designed to fit seamlessly into compatible Lincoln Electric torch assemblies and wire delivery systems, minimizing setup time and reducing the risk of component mismatch. Whether utilized in automated manufacturing cells or manual heavy fabrication, this contact nozzle delivers the durability required to keep production lines moving efficiently.

Proper maintenance of the welding circuit includes regular inspection and replacement of contact nozzles. As the bore wears over time due to the mechanical friction of the moving wire and electrical erosion, the arc can become unstable. Replacing worn tips with the KP2928-1 restores the electrical efficiency of the system, ensuring that your welding parameters are translated accurately to the workpiece. This attention to detail in consumable management directly correlates to higher quality welds and fewer rework requirements.
