CCD3550 - Dinse Style 50mm Welding Cable Quick Connector Set (Male & Female)

Get Connected Fast with the 50mm Dinse Set

Stop wasting time with bolted lugs or worn-out connectors that get hot and kill your arc stability. The CCD3550 Dinse Connector Set is your go-to solution for building reliable, quick-disconnect welding leads. Whether you are extending your reach across the shop or replacing a busted plug on your machine, this set gives you everything you need—both the male and female ends—to get back to burning rod. Designed for 50mm² cable (which is roughly your standard 1/0 AWG), these connectors are built to handle the heat and the current without breaking a sweat.

We know that welding cables take a beating. They get dragged over concrete, stepped on, and covered in grinding dust. That’s why these connectors feature tough rubber insulators that don't just crack the first time you drop them. The real magic, though, is in the connection itself. The brass parts are machined so they fit together perfectly. A simple push and twist locks them in solid. You can feel the cam engage, pulling the joint tight so you don't lose any amperage at the connection point. A tight connection means a smoother arc and better welds.

Installation is a breeze. You don't need special crimping tools for most setups; just strip your cable, slide it in, and tighten it down securely. The set comes with the necessary sleeves to make sure you get a good bite on the wire strands. Use these to create extension cords that you can add or remove in seconds, or to upgrade your ground clamp and stinger leads to a quick-connect system. If you're tired of dealing with loose connections or want the flexibility to change out your leads on the fly, this 50mm Dinse set is the upgrade your rig needs.
