Tweco L-3040 Copper Hammer Lug for 3/0-4/0 Cable

Reliable Connections for Your Welding Leads

When you are out in the shop or on a job site, a loose or poor cable connection can ruin your arc and overheat your equipment. The Tweco WeldSkill Hammer Lug is the fix you need for terminating your heavy 3/0 and 4/0 welding cables. Built by Tweco, a name synonymous with quality in the welding industry, these lugs are tough, conductive, and incredibly easy to install, even if you don't have a fancy crimper on hand.

These are called "Hammer Lugs" for a reason. You simply strip your cable, slide it into the flared end of the lug, and strike it with a hammer (using a blunt punch or just a solid hit) to crimp the copper down onto the wire. It creates a rock-solid mechanical bond that won't pull out. If you prefer, you can also solder them for an even more permanent electrical bond. The lug features a handy peep hole on top so you can see exactly when your wire is fully seated, taking the guesswork out of the installation.

Made from pure copper, these lugs handle the heat and current of heavy welding without melting down or causing voltage drops. The 17/32-inch hole is perfect for the 1/2-inch studs found on most welders and ground clamps. Whether you are building new leads from scratch or repairing a damaged cable end, keep a few of these Tweco lugs in your toolbox to ensure you always have the power you need at the arc.
