The Lincoln Electric Magnum PRO 550 Mechanized MIG Gun (K52250-25C) is a premier solution for industrial automation and hard automation welding cells. Designed to deliver high-amperage performance without the complexity of water cooling, this gun is rated for 550 amps at 100% duty cycle when using CO2 shielding gas. This capability makes it an exceptional choice for heavy fabrication environments where durability and continuous operation are critical.
At the core of the Magnum PRO series is Lincoln's proprietary consumable technology. The gun utilizes Copper Plus® contact tips, which feature a larger diameter and greater mass than standard tips. This design improves heat dissipation, keeping the tip cooler and significantly extending its service life. Additionally, the Anti-Seize™ threads on both the contact tip and gas diffuser prevent the parts from fusing together, a common issue in high-heat, high-amperage applications. This feature ensures that consumable changes are quick and tool-free, minimizing downtime in automated lines.
The K52250-25C configuration includes a 25-foot cable, providing ample reach for gantry systems, side-beams, or carriage units. The mechanized barrel is designed for secure mounting in fixtures, ensuring precise tool center point (TCP) repeatability. The air-cooled architecture simplifies the overall welding system by removing the need for water circulators, coolant lines, and the associated maintenance of liquid cooling systems, while still maintaining a high output rating suitable for flux-cored and solid wire welding.
This gun is compatible with Lincoln Electric wire feeders and is engineered to withstand the rigors of continuous industrial use.
