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

Severe Duty Durability for Subarc Welding

Maximize your welding uptime and ensure consistent weld quality with the Lincoln Electric KP1962-4B1 Severe Duty Contact Tip. In the world of Submerged Arc Welding (SAW), the contact tip is the critical point of current transfer. Standard copper tips often wear out quickly due to the abrasive nature of the wire and the intense heat generated by high-amperage arcs. Lincoln Electric addresses this challenge with the KP1962-4B1, crafted from a robust beryllium-copper alloy that significantly outlasts conventional materials.

This 10-pack of contact tips is engineered for 5/32-inch (4.0 mm) wire, providing a precise fit that minimizes micro-arcing inside the tip and ensures smooth wire feeding. The superior wear resistance of the beryllium-copper alloy means the bore diameter remains consistent for longer periods, preventing the wandering arcs and poor electrical contact that can lead to weld defects. With a current capacity ranging from 600 A to 1200 A, these tips are built to handle the power required for deep penetration welds on thick steel sections.

The KP1962-4B1 is specifically designed to fit Lincoln K231-1 and K231-2 submerged arc torches. These torches are workhorses in the industry, and pairing them with severe duty consumables unlocks their full potential. The tips are compatible with water-cooled setups, which is essential for maintaining performance during long, continuous welds often found in beam fabrication and tank manufacturing.

Investing in severe duty consumables like the KP1962-4B1 is a smart choice for any shop focused on efficiency. Fewer tip changes mean less machine downtime and more arc-on time. The consistent performance also reduces the likelihood of rework caused by contact tip failure. Equip your subarc system with Lincoln Electric's beryllium-copper tips and experience the difference in durability and arc stability.
