KP4120-1-62F-B25 - Lincoln KP4120-1-62F-B25 Magnum PRO Water-Cooled Flush Nozzle 5/8 Inch (25-Pack)

Precision and Durability for Robotic MIG Welding

Maximize the efficiency of your automated welding cells with the Lincoln Electric KP4120-1-62F-B25 Magnum PRO Gas Nozzle. Designed for professional welders and automation technicians who demand reliability, this 25-pack of nozzles is built to withstand the intense heat and spatter associated with high-amperage robotic welding. Compatible with Magnum PRO Water-Cooled Robotic Torches, these nozzles are the first line of defense for your torch front-end parts, ensuring that your equipment performs at its peak shift after shift.

Superior Heat Resistance

Water-cooled torches are essential for high-deposition welding, and your nozzle needs to be just as tough. The KP4120-1-62F utilizes high-quality copper alloy construction optimized for water-cooled applications. This material choice, combined with the nozzle's design, allows it to resist the adhesion of welding spatter, making automated reaming cycles more effective and less frequent. The result is a cleaner nozzle that maintains proper gas flow dynamics for longer periods, reducing the risk of weld defects caused by turbulent shielding gas.

Flush Geometry for Versatility

Selecting the right nozzle stickout is key to arc performance. This model features a flush tip relationship, meaning the contact tip is level with the nozzle exit. This geometry is excellent for a wide range of welding positions and joint types, providing a stable arc and robust gas coverage. It minimizes the risk of the nozzle shorting against the workpiece while still keeping the gas shield tight to the puddle. The 5/8-inch (15.9 mm) bore is a standard size for structural steel and heavy fabrication, offering a wide umbrella of shielding gas.

Magnum PRO Performance

As part of the Magnum PRO line, these nozzles are designed with Lincoln Electric's focus on consumable longevity. The thread-on base ensures excellent electrical and thermal conductivity, preventing the nozzle from overheating and seizing. Whether you are welding mild steel, stainless, or aluminum in a robotic cell, the KP4120-1-62F-B25 provides the consistency required for automated processes. Keep your robots running and your welds clean with these industrial-grade nozzles.
