95151122 - Tweco L-2040 Ball-Point Mechanical Cable Lug 2/0-4/0

High-Efficiency Mechanical Connection

The Tweco 9515-1122 (Model L-2040) Twin Ball-Point Lug is a premium mechanical connector designed for the rigorous demands of industrial welding environments. Engineered from a high-grade copper alloy, this lug offers superior electrical conductivity, minimizing voltage drop across the connection point. Unlike traditional crimp or solder lugs, the ball-point design utilizes a specialized set screw that applies substantial pressure to the cable strands without shearing them. This ensures a gas-tight connection that maintains integrity even under thermal cycling and vibration.

This specific model is sized to accommodate welding cables ranging from 2/0 to 4/0 AWG, making it a versatile choice for medium to heavy-duty power sources. The 17/32-inch stud hole is precision-drilled to fit standard 1/2-inch output studs found on most welding machines and ground clamps. The mechanical nature of the connection allows for field installation using only a hex key, eliminating the need for specialized crimping tools or open-flame soldering equipment. This feature is particularly valuable for maintenance teams requiring rapid turnaround on cable repairs.

The "Twin" designation in the product family often refers to the robust nature of the clamping mechanism or specific body geometry designed to handle high amperage loads efficiently. With a flared cable entry, operators can easily insert frayed or spread cable ends, reducing preparation time. The lug is fully reusable, offering long-term value and flexibility for shop setups that frequently reconfigure equipment.
