6290A-0 - Generic Harris Style 6290 Size 0 Acetylene Cutting Tip

Precision Cutting with Harris-Style 6290-0 Acetylene Tips

Get the job done right with this durable Size 0 cutting tip, designed as a direct replacement for the widely used Harris 6290 series. If you own a Harris torch or a compatible Harris-style cutting attachment, this tip is an essential addition to your consumables kit. It is specifically engineered for oxy-acetylene cutting, leveraging the high flame temperature of acetylene to slice through carbon steel with ease. The Size 0 orifice is rated for cutting metal up to 5/8" (approx. 16mm) thick, making it a versatile choice for a wide range of applications, from automotive repair and structural steel work to farm maintenance and hobbyist fabrication.

One of the standout features of this tip is its medium preheat capability. The preheat holes are arranged to provide a balanced cone of fire around the cutting oxygen stream. This design helps maintain the necessary kindling temperature of the steel as you move the torch, ensuring a continuous cut without losing the puddle. It strikes a perfect balance: hot enough to start cuts relatively quickly, but controlled enough to prevent melting the top edge of the plate excessively. This results in cleaner edges that require less grinding and cleanup before welding.

Durability is key in any welding environment, and this tip is built to last. The solid copper body resists spatter adhesion and withstands the thermal cycling inherent in flame cutting. The tip face is flat and robust, allowing for easy cleaning with standard tip cleaners if carbon deposits or slag obstruct the orifices. Because it is a one-piece acetylene tip, it is simple to install and maintain. Just hand-tighten the tip nut and give it a slight wrench snug to seat it properly in the torch head.

Why pay more for the brand name when you can get equivalent performance with this generic replacement? It fits seamlessly with your existing equipment, including the classic Harris Model 62 hand torches and Model 73 cutting attachments. Remember, this tip is designed solely for Acetylene gas; do not use it with propane or other fuel gases. Ensure your regulators are set correctly—typically around 30-40 PSI for Oxygen and 5-10 PSI for Acetylene for this tip size—and you will experience smooth, stable cutting action every time you light the torch.
