Lincoln Electric KP1966-2B1 Pressure Shoe Contact Tip 1/16 Inch (10-Pack)

Precision Arc Control with Pressure Shoe Technology

For professional welders, the contact tip is the final transfer point of welding current to the wire, making it one of the most critical components in the MIG gun assembly. The Lincoln Electric KP1966-2B1 Contact Tip is designed to address the specific challenges of welding with heavier 1/16 inch (1.6 mm) wires. Unlike standard tips that rely solely on the cast of the wire to make contact with the tip wall, this Pressure Shoe Type tip is engineered to force positive electrical contact. This results in superior conductivity and a more stable arc, which is essential when laying down heavy beads on thick materials.

One of the primary issues welders face with larger diameter wires is micro-arcing inside the contact tip. This occurs when the wire floats or loses contact with the tip wall, causing premature wear, keyholing, and eventually, burn-back. The pressure shoe mechanism mitigates this by maintaining constant pressure on the wire, ensuring that the current transfer is efficient and consistent. This leads to less heat buildup in the tip itself and significantly extends the lifespan of the consumable, allowing you to weld longer without stopping to swap out parts.

This pack of 10 tips ensures you have replacements on hand when you need them. The 1/16 inch size is a workhorse in heavy fabrication, often used for flux-cored or metal-cored wires where high deposition rates are required. Using the correct tip size and type is non-negotiable for achieving X-ray quality welds. A tip that is too loose will cause an erratic arc, while one that is too tight will cause feeding issues. The KP1966-2B1 offers the perfect balance of clearance and contact for 1.6mm wire.

When you are under the hood, you need to trust that your equipment will perform. Lincoln Electric's reputation for quality shines through in these precision-machined copper alloy tips. They resist spatter adhesion and withstand the high heat of industrial welding cycles. Upgrade your setup with the KP1966-2B1 and experience the difference that positive electrical contact makes in your weld puddle control and overall bead appearance.
