CL415-3545 - Replacement 400A MIG Gun for Lincoln LN-7 Feeder - 15ft Cable

Industrial Grade Replacement MIG Gun for Lincoln LN-7 Systems

The CL415-3545 is a premium aftermarket replacement MIG gun engineered specifically for compatibility with the classic Lincoln Electric LN-7 wire feeder series. Designed to meet the rigorous demands of industrial manufacturing and heavy fabrication, this gun is rated for 400 Amps at a 60% duty cycle using CO2 gas, making it an ideal choice for structural steel, heavy equipment repair, and general manufacturing applications where high heat and long arc times are common.

This assembly features a 15-foot (4.5-meter) coaxial cable that provides excellent flexibility and durability while maintaining stable arc characteristics. The cable is reinforced with a rugged outer jacket resistant to abrasion, cuts, and burns, ensuring longevity in harsh shop environments. The backend connection is specifically terminated to mate directly with the Lincoln LN-7 drive roll assembly and control receptacle, eliminating the need for adapters or complex retrofitting. This plug-and-play capability minimizes downtime during equipment maintenance.

The gun comes setup for .035" to .045" (0.9mm - 1.2mm) solid or flux-cored wires, covering the most common range of industrial welding wire sizes. The front-end consumables are designed to be compatible with industry-standard styles (typically Tweco #4 or Lincoln Magnum 400 style), ensuring that replacement contact tips, nozzles, and gas diffusers are easy to source and cost-effective to stock. The gooseneck is angled for optimal joint access and operator comfort, while the handle features an ergonomic grip with a responsive trigger switch tested for high-cycle reliability.
