High Capacity and Versatility: Rated up to 350 amps and compatible with 1/0 to 2/0 welding cable sizes (50-70 mm²), these welding connectors work with a wide range of welding machines and applications. They are suitable for professional welders and DIY users who require reliable, high-capacity connections in various welding environments. 3 Pack Welding Cable Connections: This LC-40 cable connector set includes three pairs designed to create secure, stable, and low-resistance connections between welding leads, helping maintain electrical integrity and consistent performance in demanding welding operations while reducing downtime and improving workflow efficiency. Robust Construction: These welding cable quick connectors are machined from brass for excellent conductivity and durability, paired with heat and cold- protective covers. This rugged design helps them withstand harsh shop conditions, frequent handling, and temperature changes without compromising performance or safety. Complete Connection Solution: Each welding lead connector pair includes one male and one female quick connector, providing a full solution for setting up or extending welding cables. Ideal for frequent cable changes, polarity reversals, or swapping between machines, it simplifies setup and supports higher productivity in busy workshops. Welding Lead Adapters Enhanced Performance: LC-40 welding connectors are engineered for maximum conductivity and reliability, using a cam-type positive stop and lock mechanism for secure engagement. The face-to-face contact design reduces resistance, supports stable arcs, and helps maintain a safe, efficient overall welding setup., Weight: 2.58161308802 Pounds, Manufacturer: Teuypty
