OVERVIEW

Reliable Power for Your Welding Leads

Every welder knows that a good arc starts with a good connection. If your cable connectors are worn, loose, or mismatched, you're losing power before you even strike an arc. This Lenco LC-40 Style Male Connector is the perfect solution for welders who prefer the flexibility of #2 or #4 AWG cable but need to plug into machines or extension leads set up for standard LC-40 connections. It gives you the best of both worlds: the lightweight maneuverability of a thinner lead and the robust, secure lock of a heavy-duty industrial connector.

Built for the Shop Floor

Cheap plastic connectors crack when you drop them; this one doesn't. It features a tough vulcanized fiber cover that can take a beating. Whether it's getting stepped on, dragged over steel grating, or hit with hot sparks, the cover stays intact, keeping you safe from electrical shocks. Inside, the precision-machined brass body ensures that your current flows smoothly. The cam-lock design is simple and effective—just plug it in and give it a twist. You'll feel it lock into place, giving you the confidence that your lead won't pop out in the middle of a critical weld.

Easy Installation

Setting up your new lead is straightforward. The connector uses a strong oval-point screw to clamp down on your copper wire. This design holds tight without cutting into the strands, ensuring maximum conductivity and pull-out strength. Whether you are building a new lightweight whip for TIG welding or repairing an old stinger lead, this connector provides the professional reliability you need to keep your focus on the puddle, not your equipment.
