6290A-1 - Harris Style 6290A-1 Acetylene Cutting Tip, Size 1 (1" Cut)

Reliable Cutting Power for Harris Torches

If you are running a Harris torch rig, you know the 6290 series tips are the workhorses of the industry. The Harris Style 6290A-1 is your go-to replacement tip when you need to slice through 1-inch plate using Acetylene. Why pay more for the brand name when you can get the same clean cuts and durability with this high-quality generic style tip? It fits perfectly into any standard Harris cutting attachment or straight torch, seating flat and tight for a safe seal.

This is a Size 1 tip, which is one of the most common sizes for general fabrication and repair work. It handles metal thickness around 1 inch comfortably. The "A" in the part number stands for Acetylene—this is a one-piece solid copper tip designed specifically for the burning characteristics of acetylene gas. It features a medium preheat, which gives you enough heat to punch through mill scale or rust without melting the top edge of your clean steel too quickly. It’s the perfect balance for everyday hand cutting.

Key Features for the Welder:

• Direct Fit: No adapters needed; drops right into your Harris torch nut.
• Clean Cuts: Precision holes give you a straight oxygen stream for minimal slag and grinding.
• Durable: Solid copper withstands the heat of the job site.

To get the best life out of this tip, keep a tip cleaner handy. Spatter happens, but a quick clean of the preheat holes and the center cutting jet will keep your flame neutral and your cuts sharp. Remember to set your pressures correctly for a Size 1 tip to avoid popping or starving the flame. Whether you are chopping up scrap, fitting structural beams, or doing farm repairs, the 6290A-1 is a consumable you should always have in your toolbox.
