KP1962-4B1 - Lincoln Electric KP1962-4B1 Severe Duty Subarc Contact Tip 5/32" (10-Pack)

High-Performance Submerged Arc Contact Tips

The Lincoln Electric KP1962-4B1 is a premium Severe Duty Contact Tip designed specifically for the rigorous demands of submerged arc welding. Unlike standard MIG contact tips, subarc tips must endure prolonged exposure to high amperages and continuous duty cycles. Lincoln Electric has engineered this component using a specialized beryllium-copper alloy. This material composition provides superior hardness and resistance to deformation at elevated temperatures, ensuring that the tip maintains its structural integrity and bore precision even under extreme welding conditions.

This contact tip is precision-machined to accommodate 5/32-inch (4.0 mm) welding wire, a common size for heavy structural and industrial fabrication. The tight tolerance of the bore ensures optimal electrical conductivity and consistent arc stability, which are critical for achieving high-quality, defect-free welds in thick materials. The tip is rated for an impressive amperage range of 600 A to 1200 A, making it suitable for heavy-deposition applications where standard tips would fail prematurely.

Designed for seamless integration, the KP1962-4B1 is fully compatible with Lincoln Electric's K231-1 and K231-2 Submerged Arc Torches. These torches are industry standards for automated and semi-automated welding, and using genuine Lincoln Electric consumables ensures that the entire system operates at peak efficiency. The tip is also designed for water-cooled applications, allowing for effective heat dissipation that further extends the service life of the consumable.

Supplied in a package of 10, these contact tips offer excellent value and convenience for high-volume welding operations. By choosing the KP1962-4B1, fabricators can reduce the frequency of downtime associated with tip changes, thereby increasing overall throughput. Whether used in shipbuilding, pressure vessel manufacturing, or pipe fabrication, these severe duty tips provide the reliability and performance professionals expect from Lincoln Electric.
