KP4121-1-62S - Magnum PRO Robotic Water-Cooled Nozzle, 5/8 in, Stickout

Magnum PRO Performance for Robotic Welding

Maximize the efficiency of your robotic welding cells with the Lincoln Electric KP4121-1-62S Magnum PRO Bottleneck Gas Nozzle. Designed for professional industrial applications, this nozzle is built to handle the heat. If you are running Magnum PRO Water-Cooled Robotic Torches, you know that downtime for consumable changes kills productivity. This nozzle is engineered to last longer and perform better, keeping your robots welding and your production lines moving.

Precision and Access
The bottleneck shape of this nozzle is a game-changer for accessing hard-to-reach joints. By tapering down to a 0.625-inch (15.9 mm) opening, it allows the robotic torch to maneuver into tighter spaces without sacrificing gas coverage. The "Stick Out" configuration is ideal for welders and programmers who require the contact tip to be positioned closer to the work piece relative to the nozzle edge, often necessary for short-circuit transfer or specific root pass applications where arc visibility and control are paramount.

Superior Cooling and Durability
Heat is the enemy of MIG consumables. The KP4121-1-62S utilizes a thread-on design that does more than just hold the nozzle in place; it creates a solid thermal bridge to the water-cooled torch neck. This efficient heat dissipation prevents the nozzle from overheating, which in turn minimizes spatter buildup. Less spatter sticking to the nozzle means less time spent on nozzle cleaning cycles and reaming, and more time spent depositing metal. The robust materials used in Lincoln's Magnum PRO line resist deformation and wear, ensuring consistent gas flow dynamics throughout the life of the part.

Reliable Shielding
Consistent gas coverage is non-negotiable for quality welds. The precision machining of the KP4121-1-62S ensures a concentric gas flow that protects the molten puddle from atmospheric contamination. Whether you are welding at high amperages or utilizing pulse waveforms, this nozzle delivers the laminar flow needed for porosity-free results. Upgrade your robotic expendables to Lincoln Electric's Magnum PRO series and experience the difference in durability and performance.
