The K3055-2-10-45 package is designed to maximize uptime by combining durable construction with long-lasting consumables.

Built for the Welder

Operator comfort is a priority with the Magnum PRO Curve series. The classic curved handle is lightweight and ergonomically balanced to sit naturally in the hand, reducing wrist strain and fatigue over long shifts. Additionally, the gun features a rotating tube and a convenient hanger clip, allowing for any number of hand positions to suit the specific joint configuration or to navigate tight corners. This focus on ergonomics translates to better weld control and happier operators.

Copper Plus® Technology

Stop wasting time changing contact tips. The Magnum PRO Curve 400 comes equipped with Lincoln's Copper Plus® contact tips, which are designed with a larger mass to dissipate heat more effectively than standard tips. This innovation keeps the tip cooler, prevents wire burn-back, and significantly increases the life of the expendable parts. Combined with the secure thread-on nozzle and diffuser system, this gun ensures stable arc performance and consistent gas coverage, weld after weld.
