95151110 - Tweco L-1110 Mechanical Ball-Point Lug for 1/0-4/0 Cable

High-Efficiency Mechanical Connection for Heavy-Duty Welding

The Tweco 95151110 (Model L-1110) Ball-Point Lug represents a premium solution for terminating welding cables ranging from 1/0 to 4/0 AWG. Engineered for professional industrial environments, this lug utilizes Tweco's signature ball-point screw technology. Unlike traditional flat-end set screws that can shear and damage fine copper strands during tightening, the ball-point screw applies radial pressure, spreading the strands firmly against the lug body. This ensures a gas-tight mechanical bond that maximizes electrical conductivity and minimizes resistance-generated heat.

Manufactured from a high-grade copper alloy, the L-1110 offers exceptional current carrying capacity, making it ideal for high-amperage welding circuits. The body features a 17/32-inch stud hole, perfectly sized for standard 1/2-inch output studs found on most industrial power sources and wire feeders. The flat bottom surface of the lug is machined to provide optimal surface area contact, further reducing voltage drop at the connection point.

Installation is straightforward and requires no specialized crimping tools or soldering equipment—only a 7/32" hex wrench is needed. This makes the L-1110 an excellent choice for field repairs or shop setups where flexibility and speed are paramount. The mechanical nature of the connection also means the lug is fully reusable; if a cable becomes damaged, it can be removed and the lug re-installed on a fresh section of cable, providing long-term value and reduced waste.
