K4700-1-6-116A - Lincoln Magnum PRO Curve 300 Aluminum MIG Gun, 10ft, Lincoln Rear

Cost-Effective Aluminum MIG Solution

Upgrade your aluminum welding setup with the Lincoln Electric Magnum PRO Curve 300 AL Push Gun, the lowest cost solution for high-quality aluminum welding over short distances. While feeding soft aluminum wire through a standard MIG gun can often lead to feeding issues and frustration, the Curve 300 AL is engineered specifically to handle 3/64" and 1/16" aluminum wires with ease. The 10-foot cable length is the sweet spot for push feeding, allowing for a rigid liner setup that supports the wire column and delivers it smoothly to the contact tip.

This gun is built for performance and longevity. It utilizes Lincoln's premium Magnum PRO expendables, which are designed with welding arc performance in mind. The included Copper Plus contact tips resist overheating and wear, meaning you spend more time welding and less time swapping out parts. The patent-pending Anti-Seize tip and diffuser thread design ensures that your consumables stay tight during operation but release easily when it's time for service. The 300A class handle is durable yet lightweight, providing the maneuverability needed for precise aluminum bead placement.

The K4700-1-6-116A package is a complete solution that includes the gun, a 30-degree gun tube, and a full set of aluminum-specific consumables. It also comes pre-configured with the K466-6 Lincoln backend connector, ensuring seamless compatibility with your existing Lincoln Electric power sources. Whether you are repairing aluminum trailers, fabricating tanks, or performing general maintenance, this push gun offers the reliability of a professional tool at a price point that makes sense for your business.
