KP3075-1-50S - Lincoln Magnum PRO 100L/175L Thread-On Nozzle, 1/2" ID, 1/4" Stickout

Upgrade Your Magnum PRO Gun with the KP3075-1-50S

If you are running a Lincoln Electric Magnum PRO 100L or 175L MIG gun, the KP3075-1-50S is the reliable workhorse nozzle you need in your kit. Welding can be a messy job, and spatter buildup inside your nozzle is one of the biggest annoyances that can ruin your gas coverage and lead to porosity. Lincoln Electric addresses this with a high-quality nickel plating on these nozzles. This slick finish makes it much harder for hot spatter to stick, meaning you spend less time scraping out your nozzle and more time laying beads.

The "stickout" refers to the relationship between the nozzle end and the contact tip. This model features a 1/4-inch stickout, which means the nozzle extends slightly past the tip. This is excellent for general purpose welding as it helps protect your contact tip from accidentally touching the work surface, which can cause burn-backs. The 1/2-inch opening is the "Goldilocks" size—large enough to provide great gas coverage for standard steel welding, but narrow enough to see your puddle clearly.

One of the best features is the thread-on design. We've all fought with slip-on nozzles that either fall off when they get hot or get stuck so tight you need vice grips to turn them. The KP3075-1-50S uses coarse threads that lock on securely but are designed to unscrew easily, even after a long session of heating up and cooling down. Whether you are working on automotive repairs, light fabrication, or hobby projects, this nozzle ensures your shielding gas gets exactly where it needs to go.
