Lincoln Electric 1501250 Cutting Tip 3NX Natural Gas

Product Description

The LINCOLN ELECTRIC 1501250 is a brass cutting tip designed for oxygen/acetylene torch systems operating on natural gas. Tip number 3NX, it threads onto compatible cutting attachments and torch handles to deliver a focused cutting flame for ferrous and non-ferrous metals. The all-brass construction resists heat and corrosion during high-temperature cutting operations. This tip is a single-piece consumable installed by welding and cutting professionals in fabrication shops, field pipefitting, and maintenance applications where natural gas is the fuel source.

The 1501250 cutting tip is suited for oxy-natural gas setups in both shop and field environments. It is designed to pair with specific Lincoln Electric torch bodies, cutting attachments, and handles. Compatible torch models include 42-4E, 42-4F, 980-F, 62-5E, and 62-5SSF. Compatible cutting attachment models include 49-3F, 73-3, 39-3F, and 72-3. Compatible handle models include 18-5, 43-2, and 85. Welders, pipefitters, and metal fabricators typically use this tip for straight-line and shape cutting on plate and structural stock.

Installation Notes

Installation is performed by a qualified welder or cutting professional. Before changing or seating a cutting tip, shut off all gas supply valves at both the torch handle and the cylinder regulators and bleed the lines. Thread the tip into the cutting attachment by hand first, then snug with the appropriate tip wrench — do not overtighten brass fittings. Inspect tip seating surfaces for debris or damage before lighting and verify all connections are leak-free using approved leak-detection solution.
