6290A-3 - Harris Style 6290-3 Acetylene Cutting Tip - 3 Inch Capacity

Heavy-Duty Cutting with the Harris Style 6290A-3

When you are staring down a slab of 3-inch steel, you need a tip that can handle the heat and deliver the cut. The Harris Style 6290A-3 Acetylene Cutting Tip is built for exactly that kind of work. Designed to fit your trusty Harris torch, this replacement tip is a workhorse for structural steel workers, scrap yard operators, and heavy fabricators who rely on the intense heat of oxy-acetylene to get the job done. Don't let a worn-out or clogged tip slow down your production; keeping a fresh Size 3 in your kit ensures you are always ready for the heavy lifts.

The 6290 series is legendary for its durability, and this generic replacement honors that tradition. It features the classic flat seat connection that Harris users prefer, ensuring a solid, leak-free seal every time you tighten the nut. Because it is designed specifically for Acetylene, you get that focused, high-temperature preheat flame that brings steel to ignition temperature rapidly, even on thicker plates. The medium preheat pattern is forgiving enough to handle steel that isn't perfectly clean, helping you blast through mill scale and minor rust without losing your cut.

Practical Application Tips

To get the best results with your 6290A-3, proper gas settings are key. For a 3-inch cut, you will typically want to run your oxygen pressure between 45 and 50 PSI, while keeping your acetylene in the safe and effective range of 5 to 10 PSI. Always remember to purge your lines before lighting up. If you notice your flame getting distorted or the preheat cones becoming uneven, take a minute to dress the tip face with a standard tip cleaner. A clean face and clear orifices are the secrets to a slag-free cut that requires minimal grinding later.

Whether you are cutting beams for a new building or dismantling old machinery, this tip gives you the depth and control you need. It is an economical solution that doesn't skimp on quality, giving you the clean kerf and straight drop cuts you expect from professional-grade equipment.
