OVERVIEW

Heavy-Duty Mechanical Connection for Welding Cables

The Tweco 9515-1111 (Model BP-40) Ball-Point Lug & Cover is a premium solution for terminating welding cables in industrial environments. Designed to facilitate a secure and highly conductive connection for 3/0 to 4/0 AWG welding cables, this unit utilizes Tweco's signature ball-point screw technology. This mechanical fastening method drives a ball-point screw into the cable strands, ensuring maximum contact area and current transfer efficiency without the need for soldering or specialized crimping tools.

Constructed from a high-grade copper alloy, the lug body is engineered to withstand high amperage loads typical of heavy fabrication and structural welding. The included insulating cover provides essential protection against accidental arcing and electrical shock, ensuring compliance with safety standards. This product is ideal for MRO (Maintenance, Repair, and Operations) applications where quick, reliable cable repairs or assembly is required. The reusability of the mechanical connection also reduces long-term costs by allowing the lug to be transferred to new cables when necessary.

At Josef Gas, we recommend the BP-40 for shops looking to standardize their cable connections with a system that offers both durability and ease of maintenance. Its robust design ensures minimal voltage drop across the connection, contributing to a stable welding arc and consistent performance.

FAQ

The Tweco BP-40 (9515-1111) is designed to fit 3/0 and 4/0 AWG welding cables.

No, the Ball-Point design uses a mechanical screw to secure the cable, eliminating the need for soldering.

You will need a cable stripper to remove the insulation and a hex key (Allen wrench) to tighten the ball-point screw.

Yes, the part number 9515-1111 includes both the copper lug and the protective insulating cover.

Yes, because it uses a mechanical screw connection, the lug can be removed and reinstalled on a new cable if needed.

The lug is manufactured from a high-conductivity copper alloy.

While physically it may fit, these copper lugs are primarily designed for copper welding cables. Using them with aluminum may require specific anti-oxidant compounds and careful monitoring for galvanic corrosion.

The lug is generally rated to match the amperage capacity of the 3/0 or 4/0 cable attached to it, typically suitable for applications up to 400-500 amps.
