OVERVIEW

Lincoln Magnum PRO Curve 400: Ready to Weld

Upgrade your welding setup with the Lincoln Electric Magnum® PRO Curve™ 400 Short Neck Welding Gun Ready-Pak. This heavy-duty MIG gun is a favorite among professional welders for its blend of power, comfort, and reliability. Rated at 400 amps with a 60% duty cycle, it handles thick materials and long weld runs with ease. The 15-foot cable gives you the reach you need to move around large assemblies without constantly repositioning your wire feeder.

Built for Comfort, Designed for Pros

Welding all day can take a toll, but the Magnum PRO Curve™ handle is designed to help. Its ergonomic, curved shape fits perfectly in your hand, reducing wrist strain and fatigue so you can keep your focus on the puddle. The gun is lightweight yet incredibly durable, capable of surviving the drops and drags of a busy workshop. Plus, the rotating gun tube lets you adjust the angle of the neck to get into those hard-to-reach corners without twisting your wrist into uncomfortable positions.

Save Money on Consumables

One of the biggest advantages of this gun is the Magnum PRO consumable system. It uses Copper Plus® contact tips, which are thicker and dissipate heat better than standard tips. This means they last longer and don't fuse as easily, saving you money on replacements and keeping you welding longer. The Ready-Pak includes everything you need to get started right out of the box, including a 0.045" contact tip, gas nozzle, diffuser, and liner.
