81F26 - LC-40 Male Welding Cable Connector Plug 350A

Reliable Connections for Professional Welders

When you are out on the job or deep in a fabrication project, the last thing you need is a loose ground or a hot cable connection killing your arc. The LC-40 Male Cable Plug is the industry-standard solution for building reliable, extendable welding leads. Whether you are running 1/0 whip leads or heavy 3/0 stinger cables, this connector gives you the freedom to add or remove cable length in seconds without sacrificing power delivery. Rated for 350 Amps, it handles the heat of daily stick, MIG, or TIG work without breaking a sweat.

The magic of the LC-40 is in the cam-lock design. Unlike cheap connectors that just slide together, this plug uses a positive cam action. When you twist it into a matching female receptacle, it pulls tight—really tight. This ensures that 100% of your machine's power gets to the puddle, not wasted as heat at the joint. You'll notice a more stable arc and cooler running cables. The heavy-duty rubber insulator is built to take a beating; drop it on concrete, drag it through grease, or step on it, and it keeps on working.

Installation is a breeze in the field. Strip your cable, wrap it with the included copper shim (if you use one), slide it in, and crank down the set screw. The connector covers the connection completely, keeping you safe from shocks. If you are tired of taping up frayed splices or dealing with connectors that slip apart when you drag your leads, upgrading to these LC-40 plugs is the best move you can make for your rig. They are compatible with all standard Lenco-style jacks and connectors, making them a versatile addition to your tool crib.
