## Overview

The LC40 Weldmark By Lenco Cable Connector Set delivers professional-grade welding cable connections with a robust 350-amp capacity. Featuring precision-machined brass components and a cam-action design, this male/female set ensures secure, loss-free electrical flow. Proudly made in the USA, it combines durability with lightweight versatility, ideal for any serious welding setup demanding reliability and ease of use.

## Description

The advanced design of Lenco cable connectors offers many advantages over older styles. Metal parts are precision machined from specially shaped brass extrusion. Cam action design of male half connector pulls the two halves tightly together

Review: Great product - Great product
Review: Great quick disconnects - These are easy to install and they work great. No loss in current throughput. I added the mounted connectors to my engine driven welder (Bobcat 250 EFI) and these to my cables. I started with 50 feet each of 2/0 copper, but then cut those in half. This allows more flexibility in cabling while making the leads lighter when the length isn’t needed. I’m probably going to make another set of 25 foot leads so I can make up to 75 feet on each lead (or longer asymmetric lead lengths if the job allows a shorter ground on a metal building, for example).
