Lincoln Electric KP4121-1-62R Magnum PRO Bottleneck Gas Nozzle

The Lincoln Electric KP4121-1-62R is a premium gas nozzle engineered specifically for the rigorous demands of automated welding environments. Designed for use with Magnum PRO Water-Cooled Robotic Torches, this nozzle is an essential component for maintaining consistent weld quality and operational efficiency in high-volume production lines. The nozzle features a 0.625-inch (15.9 mm) bore diameter, which is a standard size suitable for a wide range of wire diameters and shielding gas flow rates, ensuring adequate coverage of the weld pool to prevent porosity and contamination.

One of the defining characteristics of this model is its bottleneck shape. Unlike standard straight nozzles, the bottleneck design tapers towards the outlet, significantly improving visibility and access to tight joints or complex workpiece geometries. This makes it an ideal choice for robotic arms that need to maneuver into restricted spaces without compromising the gas shield. Furthermore, the nozzle is designed with a recessed contact tip relationship. By positioning the contact tip slightly back inside the nozzle, the tip is better shielded from the intense heat of the arc and molten spatter. This configuration is particularly beneficial in high-heat applications, as it reduces the frequency of tip burn-back and extends the lifespan of the front-end consumables.

Constructed to handle the thermal stresses of water-cooled systems, the KP4121-1-62R utilizes a secure thread-on connection. This ensures a tight mechanical fit that promotes efficient heat transfer away from the nozzle to the torch neck, preventing overheating during long weld cycles. As part of the Magnum PRO line, this nozzle integrates seamlessly with Lincoln Electric's high-performance expendables, known for their durability and ease of maintenance. Whether you are welding mild steel, stainless, or aluminum in a robotic cell, this nozzle provides the reliability needed to keep your automation running smoothly.

Key Features:

• Optimized Geometry: Bottleneck shape allows for superior joint access in robotic applications.
• Thermal Management: Designed for water-cooled torches to withstand high duty cycles.
• Consumable Protection: Recessed tip placement reduces spatter adhesion on the contact tip.
• Secure Fit: Thread-on mechanism ensures concentricity and stability.
