The Tweco T-340 Copper Cable Lug (SKU: 9520-1103) is a premium-grade electrical connector designed specifically for the rigorous demands of industrial welding applications. Engineered to accommodate welding cables ranging from 3/0 to 4/0 AWG, this lug provides a critical interface between your power source and the welding circuit. The T-340 is manufactured from a high-conductivity copper alloy, which is essential for minimizing voltage drop and preventing overheating at the connection point—a common issue with inferior connectors that can lead to arc instability and equipment damage.
This specific model features a 17/32-inch stud hole, making it perfectly sized for mounting onto standard 1/2-inch studs found on most heavy-duty welding power supplies and ground clamps. The design includes a flared cable entry, which significantly simplifies the process of inserting stranded welding cable, ensuring all strands are captured for maximum current carrying capacity. The lug is versatile in its installation methods; it can be permanently attached via soldering for the highest electrical integrity or swaged (crimped) using appropriate heavy-duty tooling for a strong mechanical bond.
In professional environments where equipment reliability is paramount, the Tweco T-340 stands out due to its robust wall thickness and structural integrity. It resists deformation under torque and withstands the thermal cycling inherent in high-amperage welding. Whether you are outfitting a new fleet of welding machines or repairing damaged leads in a maintenance shop, the T-340 ensures that the full power of your machine reaches the arc. Its corrosion-resistant properties also make it suitable for use in harsh shop environments where exposure to fumes and humidity is expected.
By choosing genuine Tweco components, operators ensure compatibility and safety. The T-340 is part of Tweco's extensive line of cable accessories, known globally for setting the standard in welding connectivity. This lug is not just a connector; it is a safeguard for your welding performance, ensuring that resistance is kept to a minimum and efficiency is maximized.
