Koike 106-3 Propane Cutting Tip, Size 3 (1-1/2" Cut)

Clean Cuts with the Koike 106-3 Propane Tip

Upgrade your cutting setup with the Koike 106-3, a Size 3 cutting tip designed specifically for welders and fabricators using Propane or LPG. If you are cutting 1-1/2 inch steel, this is the go-to tip for getting the job done right the first time. Unlike standard acetylene tips, this 2-piece nozzle is built to handle the unique flow requirements of propane, giving you a hot, stable pre-heat flame that starts cuts quickly and maintains speed across the plate.

Why Choose the 106 Series?

We all know that cleaning up slag is the worst part of any cutting job. The Koike 106-3 is engineered to minimize that hassle. Its precision design delivers a tight, focused oxygen stream that blows molten metal away cleanly, leaving you with a smooth edge that requires little to no grinding. The "minimal kerf" design means you are removing less metal, which translates to faster travel speeds and less heat input into your workpiece. It’s perfect for structural steel, heavy equipment repair, and general fabrication where cut quality matters.

Dialed-In Performance

Getting the best performance out of this tip is easy when you set your regulators correctly. For the Size 3 tip, set your Oxygen to 45 PSI and your Propane to roughly 3-4 PSI (specifically 3.6 PSI). These settings are the sweet spot for cutting 1.5-inch plate, ensuring you don't waste gas or lose the cut mid-way. The tip is also designed with safety in mind, featuring internal geometry that helps prevent flashbacks, keeping you safe while you work.

Built for the Shop

Whether you are running a Koike torch or a compatible handle, this tip fits right in. It’s durable, reliable, and consistent. Stop fighting with messy cuts and inconsistent flames—switch to a high-quality Koike style tip and see the difference in your edge quality. It’s a small investment that pays off in saved time and cleaner parts.
