The Lincoln Electric KP21T-62 is a premium replacement gas nozzle designed specifically for the Magnum 100L series of MIG welding guns. This component is critical for directing shielding gas around the welding arc and puddle, preventing porosity and ensuring high-quality weld deposits. With an inner diameter of 0.625 inches (15.9 mm), this nozzle provides a generous gas envelope, making it suitable for a variety of standard welding applications including short-circuit transfer on mild steel.
One of the defining characteristics of the KP21T-62 is its "fixed" design. Unlike adjustable slip-on nozzles that allow the operator to vary the nozzle position relative to the contact tip, this fixed nozzle seats in a specific location. This ensures a predetermined recess for the contact tip, which helps maintain a consistent electrical stick-out (ESO). For industrial operations and maintenance repair organizations (MRO), this consistency reduces process variability and helps standardize weld quality across different operators.
Manufactured from durable copper alloy, the nozzle is built to withstand the intense heat and spatter associated with MIG welding. It is rated for use with 100-amp guns, commonly found on compact Lincoln Electric power sources. Regular inspection and cleaning of the nozzle are recommended to maintain optimal gas flow and prevent spatter bridging, which can cause electrical shorts.
