LC-40R - Lenco Style LC-40 Red Welding Cable Connector Set (1/0 - 3/0)

High-Performance LC-40R Cable Connector Set

The LC-40R Cable Connector Set is an essential component for professional welding setups requiring reliable, high-amperage power transmission. Designed to accommodate a versatile range of welding cable sizes including #1, 1/0, 2/0, and 3/0, this connector set is engineered to facilitate efficient current transfer with minimal resistance. The core of the connector is manufactured from a specialized high-conductivity brass alloy, machined to precise tolerances to ensure optimal electrical contact. This robust construction supports an amperage rating of up to 500 amps, making it suitable for heavy-duty industrial welding applications.

The connector utilizes a proven cam-lock design. When the male and female halves are joined and twisted, the cam action pulls the two faces together with significant force, creating a virtually watertight and vibration-proof seal. This ensures that the connection remains stable even in rugged working environments where cables are frequently dragged or repositioned. The set includes both the male and female components, along with their respective insulating covers.

Safety and durability are paramount in the design of the LC-40R. The insulating covers are molded from a special rubber compound that is resistant to heat, cold, oil, and ozone. The red coloration serves a functional purpose, allowing operators to easily identify positive or negative leads at a glance, thereby reducing setup errors. Installation is straightforward, utilizing a large oval-point set screw and a copper shim to secure the cable strands firmly without damage, ensuring a mechanical bond that matches the electrical performance.
