RL1020 - Heavy Duty Cast Copper Solder Lug for 1/0-2/0 Cable

Heavy-Duty Solder-On Lug for 1/0 to 2/0 Welding Cables

The RL1020 Solder-On Lug is a premium electrical connector designed specifically for the rigorous demands of industrial welding environments. Manufactured from heavy cast copper, this lug offers superior electrical conductivity and thermal properties compared to standard stamped alternatives. The casting process ensures a dense, void-free material structure that efficiently transfers high-amperage welding current from the power source to the workpiece or electrode holder, minimizing voltage drop and heat buildup at the connection point.

Engineered for 1/0 and 2/0 AWG welding cables, this lug features a generous solder cup with a flared entry, facilitating the insertion of stranded copper conductors. The solder-on design provides a permanent, gas-tight bond that is highly resistant to corrosion and vibration, ensuring a stable electrical connection over the lifespan of the cable assembly. This method of termination is particularly advantageous in applications where mechanical crimping tools are unavailable or where a sealed, monolithic connection is preferred to prevent oxidation within the wire strands.

The lug's robust construction includes a substantial mounting pad with a precision-drilled stud hole, allowing for secure attachment to welding machine output terminals, ground clamps, or other high-current distribution points. Its heavy wall thickness provides mechanical strength to withstand the physical stress of daily use, including dragging and pulling common in workshop environments. By utilizing high-grade copper, the RL1020 ensures optimal performance for professional welders requiring reliable power delivery.
