KP3160-1-50S - Lincoln Magnum PRO 350A MIG Nozzle, 1/8" Stickout, 1/2" Bore, Thread-On

Genuine Lincoln Electric Magnum PRO Protection

Keep your welding operations running smoothly with the genuine Lincoln Electric KP3160-1-50S Gas Nozzle. This essential consumable is designed exclusively for Magnum PRO 350A MIG guns, delivering the reliability and performance you expect from Lincoln Electric. As a critical component of the gun's front end, this nozzle plays a dual role: it directs the shielding gas flow to protect the molten weld pool and helps dissipate heat from the contact tip and diffuser. Rated for 350 amps, it is built to withstand the intense thermal cycles of production welding without deforming or degrading prematurely.

The KP3160-1-50S features a 1/8-inch stickout, meaning the contact tip protrudes slightly or sits just behind the nozzle edge depending on the specific diffuser setup, generally providing a fixed relationship that helps operators maintain a consistent contact-tip-to-work distance (CTWD). The 1/2-inch bore diameter is a versatile size, offering excellent gas coverage for standard wire sizes ranging from .035" to 5/64", while the bottleneck shape improves access to restricted areas. This shape is ideal for automotive repair, structural steel fabrication, and general manufacturing where joint accessibility can be a challenge.

User-friendly features set the Magnum PRO consumables apart. This nozzle utilizes a secure thread-on system that locks it firmly in place, preventing it from falling off during overhead welding or vibration. The threads are engineered to be coarse, which resists seizing—a common frustration with standard nozzles after long periods of heat exposure. Additionally, the exterior is nickel-plated to resist spatter buildup. This means less time scraping out the nozzle and more time welding. Whether you are replacing a worn-out part or stocking up for a big job, the KP3160-1-50S ensures your Magnum PRO 350A gun performs at its best, delivering clean, high-quality welds shift after shift.
