K2647-11 - Lincoln Magnum PRO 550 Robotic MIG Gun, 11ft External Dress

Built for the Robot, Designed for the Welder

When your production line relies on automation, downtime is the enemy. The Lincoln Electric Magnum PRO Robotic 550 Welding Gun (K2647-11) is built to keep your robots running longer and your welds looking better. This 550-amp air-cooled beast is designed for high-volume manufacturing where stopping to cool down a torch isn't an option. With a 100% duty cycle using CO2, you can push this gun to the limit shift after shift without overheating.

One of the biggest headaches in robotic welding is maintaining the Tool Center Point (TCP) after swapping out a nozzle or tip. Lincoln Electric solved this with their Single TCP design. Whether you are running 350A or 550A consumables, the TCP remains constant. This means you can switch out parts and get the robot back to welding immediately—no touch-ups or reprogramming required. The external dress package with an 11-foot cable keeps lines organized and accessible, reducing cable stress during complex robot movements.

We know that electrical connections are often the weak point in MIG guns. The Magnum PRO features the HexConnect™ bushing, which replaces standard rotating connections with a hexagonal design that provides full-face contact. This means better current transfer, less heat buildup at the connection, and a more consistent arc at the workpiece. Plus, the gun tube is armored with an aluminum jacket that sheds spatter easily, keeping the front end clean and reducing maintenance time.

The cable system is another area where this gun shines. It has been tested to withstand twice the abuse of standard industry cables, ensuring it holds up to the constant twisting and bending of robotic arms. If you are looking for a gun that simplifies consumable inventory, maintains precision, and withstands the toughest shop environments, the Magnum PRO 550 is the upgrade your cell needs.
