95201105 - Tweco T-120 Copper Solder Lug for 1/0-2/0 Cable

Reliable Power Connections with Tweco T-120 Solder Lugs

The Tweco T-120 Copper Solder Lug (Part No. 9520-1105) is a critical component for fabricating high-performance welding leads and ground cables. Designed for industrial environments where electrical efficiency is paramount, this lug is engineered to fit 1/0 and 2/0 AWG welding cables. Unlike standard crimp lugs, the T-120 is designed specifically for a soldered connection. This method fills the voids between the cable strands and the lug wall with solder, creating a solid, unified mass that offers the lowest possible electrical resistance.

Manufactured from a high-grade copper alloy, the T-120 ensures that your welding machine delivers its full amperage to the arc without significant voltage drop at the connection points. The lug features a 17/32-inch stud hole, making it perfectly sized for standard 1/2-inch studs found on many welding power sources and ground clamps. The cable entry point is slightly flared, a thoughtful design detail that prevents fraying during insertion and simplifies the assembly process.

At Josef Gas, we recommend the Tweco T-Series lugs for permanent shop installations and heavy-duty field repairs where vibration or thermal cycling might loosen mechanical connections. By soldering your connections, you ensure a bond that is impervious to corrosion and mechanical pull-out, extending the life of your welding cables and protecting your equipment from overheating terminals.
