K471-10 - Lincoln Magnum 400 MIG Gun, 400A, 20ft Cable, .035-.045 Liner

Comfort and Power for the Professional Welder

When the heat turns up, you need a gun that can take it without wearing you out. The Lincoln Electric Magnum 400 (K471-10) is built specifically for operator comfort during high-amperage welding. If you are running long beads at 400 amps, you know that radiant heat and hand fatigue are your biggest enemies. The Magnum 400 fights back with Lincoln's classic curved handle design. Lightweight and perfectly balanced, this handle provides a natural, comfortable grip that reduces strain on your wrist and forearm, allowing you to maintain steady control and focus on the puddle, even at the end of a long shift.

This isn't just a comfortable gun; it's a workhorse. The 20-foot cable gives you the freedom to move around your workpiece without constantly tugging on the feeder. The cable itself is tough—wrapped in an abrasion-resistant rubber jacket that resists cuts and tears from sharp metal edges. You can drag it, pull it, and work it hard, and it will keep delivering the power you need. The gun tube is also armored, protecting it from the inevitable knocks and drops that happen in a real welding environment. Plus, the polished metal jacket on the tube helps reflect radiant heat away from the gun, keeping it cooler during operation.

Reliability is key when you are under the hood. The Magnum 400 features a heavy-duty, one-piece trigger assembly that is designed to last. It uses silver contacts for a sure start every time you pull the trigger, and the housing is heat-resistant to stand up to spatter. The gooseneck rotates, giving you the flexibility to get the perfect gun angle in tight corners or out-of-position welds. Whether you are welding structural steel, heavy equipment, or general fabrication, this gun gives you the reach, the power, and the comfort to get the job done right.

The K471-10 comes ready to run .035 to .045 wire right out of the box. It includes everything you need to hook up and start welding: contact tip, gas diffuser, nozzle, and liner. It’s the perfect upgrade for your heavy-duty MIG setup, combining the legendary reliability of Lincoln Electric with the practical features professional welders demand.
