99001140 - Tweco Mechanical Cable Lug Crimper and Splicing Tool

Professional Cable Installation Made Simple

The Tweco Lug-Set Block & Punch is a time-tested solution for welders and fabricators who need to create secure, high-conductivity connections on welding cables without the bulk or expense of hydraulic crimping equipment. Designed with the realities of field work in mind, this two-piece tool set allows for the mechanical installation of copper cable lugs and splicers using nothing more than a standard hammer. Its simplicity is its greatest strength, ensuring that you can repair damaged cables or fabricate new leads anywhere, from the shop floor to remote job sites.

Manufactured from high-quality hardened steel, the block and punch are built to withstand repeated impact and the rigors of industrial environments. The design features a specialized cavity in the block that supports the lug or splicer, while the punch is engineered to deform the connector wall effectively, driving it deep into the copper strands of the cable. This creates a solid mechanical bond that ensures excellent electrical conductivity and resistance to pull-out, which is critical for maintaining stable arcs and preventing overheating in high-amperage welding circuits.

This tool is versatile enough to handle a broad range of cable sizes, accommodating everything from lighter 6 AWG cables up to heavy-duty 4/0 welding leads. Whether you are setting up a new fleet of welding machines or performing emergency repairs on a severed ground lead, the Tweco Lug-Set provides a reliable method for getting your equipment back up and running quickly. It is an essential addition to any welder's toolbox, offering a perfect balance of portability, durability, and functionality.

By choosing the Tweco Lug-Set, you are investing in a legacy of quality. Tweco has been a leader in welding accessories for decades, and this tool reflects their commitment to practical, robust solutions for professional tradespeople. Forget about hauling heavy crimpers or waiting for shop repairs; with this block and punch, you have the power to make professional connections right in the palm of your hand.
