K3359-120IC/10L - Lincoln Magnum PRO 550 Robotic Gun for Fanuc 120iC/10L

Precision Engineering for Automated Welding

The Lincoln Electric Magnum PRO Robotic 550 Welding Gun (K3359-120iC/10L) represents the pinnacle of performance for automated manufacturing environments. Specifically engineered to integrate seamlessly with the Fanuc ARC Mate 120iC/10L robot, this thru-arm, air-cooled welding gun is designed to maximize uptime and weld consistency. In high-volume production, reliability is paramount, and the Magnum PRO series delivers with a robust construction that withstands the rigors of continuous operation. The thru-arm design routes the cable assembly through the center of the robot arm, significantly reducing cable interference, wear, and the potential for snagging during complex articulation sequences.

At the core of this system is Lincoln Electric's innovative HexConnect™ Gun Bushing technology. Unlike traditional rotating connections that rely on single-line contact—which can lead to micro-arcing and inconsistent current transfer—the HexConnect design utilizes a hexagonal interface to ensure full-face contact. This guarantees optimal electrical conductivity, resulting in a more stable arc and superior weld quality. Furthermore, the cable system itself has been rigorously tested to exceed industry standards, offering double the durability of comparable models to ensure long service life even in demanding repetitive-motion applications.

Operational efficiency is further enhanced by the Single Tool Center Point (TCP) architecture. This intelligent design feature allows operators to switch between 350A and 550A expendables without altering the robot's programmed TCP. This means you can adapt the gun to different welding parameters or part requirements without the time-consuming need to reprogram the robot's path. The K3359-120iC/10L comes as a Ready-Pak®, pre-assembled with a complete set of high-performance Magnum PRO expendables, including the contact tip, gas nozzle, diffuser, and liner, allowing for immediate installation and integration into your welding cell.

Key Technical Benefits:

• Seamless Integration: Tailored fit for Fanuc 120iC/10L ensures perfect mounting and range of motion.
• Enhanced Conductivity: HexConnect bushing prevents current drop-off and heating issues.
• Versatile Maintenance: Interchangeable consumables across the Magnum PRO line reduce inventory complexity.
