K2647-5L - Lincoln Magnum PRO 550 Robotic MIG Gun, External Dress, 5.5ft Cable

Reliability That Keeps Your Robots Running

In the world of robotic welding, downtime is the enemy. The Lincoln Electric Magnum PRO Robotic 550 Welding Gun is built to keep your production lines moving and your robots welding. Designed with the welder and maintenance technician in mind, the K2647-5L model addresses the most common pain points in automated welding: cable failure, contact tip burnout, and complicated maintenance procedures. This 550-amp, air-cooled gun is a workhorse, capable of running at 100% duty cycle with CO2 gas, meaning it can handle long, continuous welds on heavy plate without overheating or requiring a cool-down period.

One of the standout features for shop floor operations is the Single Tool Center Point (TCP). We all know the frustration of changing a contact tip or nozzle and then watching the robot miss the joint because the new part sits slightly differently. With the Magnum PRO line, 350A and 550A consumables are interchangeable and designed to maintain the exact same TCP. You can swap out parts and get the robot back to work immediately—no teaching pendant required. Furthermore, the Simplified Expendable Parts Selection means you can stock fewer unique part numbers in your crib, as the consumables are compatible across the entire Magnum PRO robotic gun family.

The physical construction of the gun is ready for the toughest shop environments. The external dress configuration with a 5.5-foot cable allows for easy visual inspection and quick replacement if damage occurs, without needing to dismantle the entire robot arm. The gun tube is armored with an aluminum jacket that sheds spatter, preventing the buildup that often weighs down other torches or causes short circuits. Inside the connection point, Lincoln's HexConnect™ technology ensures a solid electrical connection every time, preventing the flickering arcs and inconsistent welds caused by poor conductivity. Whether you are welding mild steel, stainless, or aluminum, the Magnum PRO 550 delivers the consistent, high-quality arc transfer required for defect-free robotic welds.
