LC-40M - LC-40 Style Male Welding Cable Connector, Black, 1/0 - 2/0 Capacity

Get Connected and Stay Connected

There is nothing more frustrating on a job site than a loose ground or a stinger lead that keeps popping out. With this LC-40 Style Male Cable Connector, you can ensure your leads are solid, secure, and ready for current. Built for the daily grind of the welding shop or the field, this connector is the industry standard for a reason. It fits your standard 1/0 and 2/0 welding cables—the bread and butter sizes for most stick and MIG setups running up to 350 amps. If you are building new leads or repairing a damaged end, this plug gets you back up and running in minutes.

Installation is a breeze. You don't need a crimper or any specialized hydraulic tools. Just strip your cable, slide on the heavy-duty rubber boot, wrap the copper shim around your strands, and slide it into the brass body. A few turns with a 1/4" Allen wrench (hex key) drives the set screw down tight, locking the cable in place for good. The copper shim protects your cable strands from getting cut by the screw, ensuring you get full amperage flow to your arc. Once it's tight, slide the boot up and lock it on. You're done.

The cam-lock design is what sets these apart. A simple twist locks this male end into any compatible female receptacle with a satisfying "thunk." It won't wiggle loose while you are dragging leads across the floor or up a scaffold. The black insulator usually indicates a negative or ground connection in many shops, but it works just fine on either side of the circuit. The rubber material is tough—it won't crack when you drop it and it stands up to oil and grease. Stop fighting with taped-up, sparking connections and upgrade your leads with professional-grade connectors that handle the heat.
