OVERVIEW

Harris 6290-1AC Heavy Preheat Acetylene Cutting Tip

The Harris 6290-1AC is a premium two-piece cutting tip designed specifically for heavy-duty industrial applications involving acetylene gas. Engineered with a copper outer shell and a brass internal shell, this tip offers superior durability and heat resistance compared to standard solid copper tips. The "AC" designation indicates a heavy preheat capability, making this consumable an essential tool for professionals working with less-than-perfect steel surfaces in sectors such as demolition, infrastructure repair, and heavy fabrication.

One of the primary challenges in demolition and maintenance cutting is dealing with surface contaminants. Standard tips often struggle to maintain a preheat flame when faced with heavy rust, multiple layers of paint, or thick mill scale. The 6290-1AC overcomes this by delivering a concentrated, high-intensity preheat flame that burns through coatings and scale, allowing the cutting oxygen stream to penetrate the base metal effectively. This feature significantly reduces the time spent on surface preparation, increasing overall productivity in scrapyards and repair shops.

Designed to fit industry-standard Harris torches, including the 62-3E, 142-4E, and 880-E models, this tip ensures a secure, leak-free seal and optimal gas flow. The size 1 orifice is calibrated for cutting steel thicknesses ranging from 5/8 inch to 1 inch, covering a wide variety of structural and plate cutting tasks. Whether you are dismantling old machinery, repairing heavy equipment, or performing structural demolition, the Harris 6290-1AC provides the reliability and performance required for clean, consistent cuts.

Maintenance of the tip is straightforward due to its two-piece construction. The inner brass member can be easily separated from the outer copper shell for cleaning, ensuring that gas passages remain unobstructed for safe operation. By choosing genuine Harris consumables, operators ensure compatibility and safety, maintaining the integrity of their oxy-acetylene equipment and ensuring compliance with safety standards.

FAQ

This tip is designed exclusively for use with Acetylene gas.

The size 1 tip (1AC) is rated to cut steel thicknesses between 5/8 inch and 1 inch.

Heavy preheat means the tip produces a more intense preheat flame, allowing it to cut through rust, paint, and scale that would normally disrupt a standard flame.

It fits Harris torches including models 62-3E, 142-4E, 880-E, and compatible cutting attachments like the 73-3.

No, the 6290-AC series is specifically for Acetylene. For Propane, you would need a 6290-NFF or similar propane-rated tip.

The two-piece design allows you to separate the brass inner part from the copper outer shell for easy cleaning of the splines and gas passages.

This is a two-piece tip featuring a copper outer shell and a brass internal shell.

Its ability to maintain a flame against dirty, painted, or rusted surfaces makes it ideal for demolition where materials are rarely clean.
