KP2928-2 - Lincoln Electric KP2928-2 SAW Contact Nozzle 1/8 Inch

Reliable Performance for Heavy-Duty Welding

The Lincoln Electric KP2928-2 Contact Nozzle is a critical component designed for industrial welding applications requiring precision and durability. Engineered specifically for use with 1/8 inch (3.2 mm) diameter wire, this contact nozzle is typically utilized in Submerged Arc Welding (SAW) and other heavy-duty wire feeding processes. In high-amperage environments, the quality of the contact nozzle directly influences arc stability and weld integrity. Lincoln Electric has manufactured this part to exacting standards, ensuring that it meets the rigorous demands of structural steel fabrication, pipe manufacturing, and heavy equipment repair.

Constructed from a high-grade copper alloy, the KP2928-2 offers excellent electrical conductivity. This is vital for transferring welding current from the torch to the wire with minimal resistance, thereby reducing heat buildup within the nozzle itself. Excessive heat can lead to premature failure, wire burn-back, or fusion of the wire to the tip. By using genuine Lincoln Electric consumables, operators can trust in the material composition and machining tolerances that prevent these common issues. The nozzle's robust design resists mechanical wear and erosion caused by the continuous friction of feeding heavy wire, ensuring a longer service life compared to generic alternatives.

Replacing contact nozzles at appropriate intervals is essential for maintaining weld quality. As a nozzle wears, the bore hole can become oval-shaped or "keyholed," leading to poor electrical contact and a wandering arc. This instability can result in defects such as lack of fusion or irregular bead profiles. The KP2928-2 is designed to maintain its geometry longer, providing consistent wire positioning and current transfer. Whether you are running long automated seams or manual heavy-plate welds, this nozzle provides the reliability professional welders expect from the Lincoln Electric brand.

This product is sold individually, allowing shops to stock the exact quantity needed for their maintenance schedules. It is compatible with specific Lincoln Electric welding guns and torch assemblies designed for large-diameter wires. Investing in OEM parts like the KP2928-2 ensures that your equipment operates at peak efficiency, minimizing downtime and maximizing productivity in the workshop.
