K2917-120IC - Lincoln Magnum PRO 550 Robotic MIG Gun Thru-Arm Air Cooled

High-Performance Air-Cooled Robotic Welding

The Lincoln Electric K2917-120IC Magnum PRO Robotic 550 Welding Gun represents a significant leap in automated welding technology. Engineered specifically for high-duty cycle industrial environments, this gun challenges the traditional reliance on water-cooled systems for high-amperage applications. By leveraging Lincoln's proprietary Magnum PRO front-end technology, the K2917-120IC achieves an impressive 550A rating at 100% duty cycle (using CO2), allowing manufacturers to simplify their robotic cells by eliminating water coolers, coolant lines, and the associated maintenance risks of liquid leaks.

This model features a Thru-Arm design, tailored for modern robotic manipulators where the cable assembly is routed through the center of the robot's casting. This configuration minimizes cable whipping, reduces mechanical stress on the torch cable during complex articulation, and allows the robot to access tighter fixtures without the risk of snagging external cables. The "120IC" designation typically points to specific cable length and integration parameters suited for standard reach industrial robots.

Crucial to its performance is the use of Copper Plus® contact tips. These tips feature a larger diameter and more mass than standard tips, improving heat dissipation and electrical conductivity. Combined with the patent-pending anti-seize thread design on the diffuser and nozzle, the gun ensures that consumables remain easy to change even after long shifts of high-heat welding. The single-piece liner system further enhances reliability by providing a smooth, uninterrupted path for the welding wire, drastically reducing the occurrence of bird-nesting or wire shaving which can cause costly downtime in automated lines.

For facility managers and welding engineers, the K2917-120IC offers a compelling ROI by reducing the total cost of ownership. The removal of the water-cooling requirement lowers energy consumption and equipment complexity, while the extended life of Magnum PRO consumables reduces the frequency of tool center point (TCP) checks and tip changes.
