95201109 - Tweco T-120 Copper Solder Lug for #6-#2 Cable

Reliable Connections for Smoother Welds

Every welder knows that a stable arc starts with a solid ground and a good power connection. The Tweco T-120 Solder Lug is the industry standard for terminating your welding leads securely and permanently. Designed to fit #6, #4, and #2 gauge welding cables, this lug is perfect for building custom ground leads, stinger whips, or repairing damaged cable ends. When you rely on your equipment to perform daily, you can't afford voltage drops caused by loose or corroded crimp connections.

The T-120 is made from heavy-duty copper alloy, offering excellent conductivity to keep your leads running cool. The 17/32" stud hole is sized perfectly to fit the output terminals of most welders or to bolt securely onto a work table for a dedicated ground point. Because it is a solder-type lug, it provides the most secure connection possible. Once soldered, the cable and lug become one unit, preventing the wire from pulling out even under the rough tug-and-pull conditions of a busy shop or job site.

Installing the Tweco T-120 is a great way to upgrade your setup. Simply strip your cable, insert it into the flared end of the lug, heat the lug with a torch, and feed in your solder until the joint is full. The result is a professional, corrosion-resistant connection that won't let you down. Whether you are setting up a new TIG runner or fixing a beat-up stick lead, trust Tweco lugs to deliver the power you need.

Why Choose Solder Lugs?

• Permanent Bond: Solder fills the gaps between wire strands, creating a solid mass that won't loosen.
• Better Conductivity: Eliminates resistance points common in mechanical connections.
• Corrosion Resistance: The solder seals the copper strands, protecting them from shop fumes and moisture.
• Durability: Withstands the heat and physical abuse of daily welding use.
