KP2742-2-62F - Lincoln Magnum PRO 350A Flush Nozzle 5/8 Inch Bore

Genuine Lincoln Consumables for the Professional Welder

When you are under the hood, the last thing you want to worry about is your front-end consumables failing or clogging up in the middle of a bead. The Lincoln Electric KP2742-2-62F is the authentic replacement nozzle for your Magnum PRO 350A MIG gun, designed to keep you welding smoothly shift after shift. This isn't just a piece of copper; it's a critical component of the Magnum PRO system that helps keep your gun cool and your welds clean. Rated for 350 amps, this nozzle handles the heat of heavy fabrication, structural steel work, and production manufacturing without melting down or losing its shape.

The "Flush" designation on this nozzle means the end of your contact tip sits perfectly level with the end of the nozzle. Why does this matter? For many welders, a flush nozzle is the perfect middle ground. It gives you better visibility of the puddle than a recessed nozzle, allowing you to see exactly where your wire is hitting the joint. At the same time, it offers better gas coverage than a protruding tip, especially when you are working in drafty shop environments or moving fast. The 5/8-inch bore is the industry standard for a reason—it provides a wide, stable umbrella of gas (whether you are running CO2 or an Argon mix) to keep porosity out of your welds.

Let's talk about the "Slip-On" feature. If you have ever fought with a threaded nozzle that welded itself to the diffuser after a long day of high-amperage spray transfer, you know the struggle. The KP2742-2-62F eliminates that headache. It slides on and stays put with a friction fit, but when it's time to clean out the spatter or change a tip, it twists off easily. No pipe wrenches required. Plus, the nickel plating is a huge advantage. Spatter doesn't stick to nickel like it does to bare copper. Most of the time, you can just tap the gun against your glove or use a pair of welpers to flick the berries off, and you are back to burning wire. This keeps your gas flow smooth and stops those annoying interruptions.

This nozzle is designed to work seamlessly with your existing Magnum PRO 350A setup. It fits over the KP2746-2 gas diffuser and accommodates wire sizes from .035 up to 5/64 inch. Whether you are welding mild steel, stainless, or flux-cored wire, using genuine Lincoln Electric parts ensures your gun performs exactly how the engineers intended. Don't compromise your weld quality with ill-fitting generic parts; stick with the KP2742-2-62F for reliable performance.
