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

Reliable Quick Connects for Your Welding Leads

Every welder knows the frustration of short leads or the hassle of dragging heavy cables around the shop when you don't need the full length. The LC-40R Red Cable Connector Set is the standard solution for creating modular, extendable welding leads. Whether you are running 1/0, 2/0, or 3/0 cable, these connectors give you the freedom to add or remove cable lengths in seconds. No more bolting and unbolting lugs; just plug, twist, and weld.

These are the classic "Lenco-style" connectors that have been a staple in the industry for decades. They feature a simple but effective cam-lock mechanism. You just push the two ends together and give them a quarter turn. The cam pulls the brass contacts tight against each other, ensuring you get the full power of your machine at the arc without your connection getting hot. The red covers are tough—they can take being stepped on, dragged across concrete, and exposed to sparks without cracking or falling apart.

Installation is a breeze and can be done right in the field with a hex key. Strip your cable, wrap it in the provided copper shim (to protect the strands), slide it into the brass body, and crank down the set screw. Slide the rubber cover over the assembly, and you are ready to go. The red color is great for marking your positive lead or just keeping your gear organized. Rated for 500 amps, these connectors can handle the heat of almost any stick, MIG, or TIG job you throw at them.
