K4530-2 - Lincoln Magnum PRO 250L MIG Gun, 15ft, 250A, Power MIG Compatible

Industrial Grade Performance for Power MIG Series

The Lincoln Electric Magnum PRO 250L (K4530-2) is a high-performance air-cooled MIG gun engineered specifically for the Power MIG 256 and Power MIG 260 welding machines. Designed to meet the rigorous demands of medium-duty job shops and production environments, this 15-foot gun assembly delivers a robust 250 Amps at 100% duty cycle when using mixed shielding gas. This exceptional duty cycle rating ensures that the equipment can withstand continuous operation without overheating, maximizing throughput in industrial settings.

At the core of the Magnum PRO 250L's performance is Lincoln's proprietary expendable technology. The gun utilizes Magnum PRO Copper Plus contact tips, which feature a larger mass and diameter compared to standard tips. This design improves heat dissipation significantly, keeping the tip cooler and extending its service life. Furthermore, the patent-pending Anti-Seize tip and diffuser thread design prevents the common issue of parts fusing together, ensuring that consumable changes are quick and tool-free. The gun tube itself is chrome-plated, a critical feature that resists spatter adhesion and protects the front end from premature wear.

The K4530-2 comes fully assembled and ready to weld with .035" and .045" wire diameters, though it is capable of feeding wire ranging from .025" to .045" with the appropriate liner and tip changes. The integrated gun connector ensures a secure and direct fit into compatible Lincoln power sources, eliminating the need for adapters. For maintenance and repair operations (MRO) requiring reliable, continuous welding output, the Magnum PRO 250L offers a superior balance of durability and technical capability.
