OVERVIEW

Magnum PRO 550: Built for the Grind

When your welding projects demand continuous high-amperage output, the Lincoln Electric Magnum® PRO 550 Welding Gun stands ready to deliver. With a massive 550A rating at 100% duty cycle, this gun is built to withstand the heat of the toughest jobs without backing down. The K2655-4 model comes equipped with a 25-foot cable, giving you the freedom to move around large workpieces without constantly repositioning your wire feeder.

Comfort Meets Control

Welding all day can be exhausting, which is why Lincoln Electric designed the Magnum PRO series with the operator in mind. The Comfort Grip™ handle features a barrel-style design that is lightweight and perfectly balanced, allowing for a comfortable grip regardless of hand position. This ergonomic focus helps reduce fatigue during long shifts, keeping your welds steady and consistent. The Secure-Lock™ gun tube ensures the front end stays rigid and doesn't rotate unexpectedly, giving you precise control over every bead.

Save Time and Money

Downtime is the enemy of productivity. The Magnum PRO 550 fights back with Lincoln's Copper Plus® contact tips, which last longer than standard tips thanks to better heat dissipation. The innovative Anti-Seize™ threads on the tip and diffuser mean you won't be fighting with stuck parts when it's time to swap consumables. Whether you are running solid MIG wire or heavy flux-cored wire, this gun offers the reliability and ease of maintenance that professional welders trust.
