OVERVIEW

Cut Through Rust and Paint with the Harris 6290-1AC

When you are out in the field or working in a busy scrap yard, you don't always have the luxury of cutting clean, new steel. For those tough jobs involving rusted, painted, or scaled metal, the Harris 6290-1AC Cutting Tip is your go-to solution. This heavy preheat tip is designed to tackle the grimiest materials without losing its flame, ensuring you can keep working efficiently without constant interruptions to clean or grind the base metal.

The secret lies in its heavy preheat design. Unlike standard tips, the 6290-1AC projects a robust preheat flame that aggressively burns away surface contaminants like rust and old paint. This allows the cutting oxygen to engage with the steel faster and maintains the cut even when the surface condition varies. It is the perfect choice for demolition crews, maintenance teams, and anyone who needs to cut through salvaged materials quickly and effectively.

Built with the quality you expect from Harris, this tip features a two-piece construction with a durable copper outer shell and a precision-machined brass inner core. This design not only extends the life of the tip but also makes cleaning easier if splatter occurs. The size 1 tip is rated for cutting steel between 5/8 inch and 1 inch thick, making it a versatile addition to your torch kit. It fits standard Harris torches such as the 62-3E and 142-4E, as well as compatible cutting attachments like the 73-3 and 72-3.

Don't let dirty metal slow down your operation. Equip your oxy-acetylene torch with the Harris 6290-1AC and experience the difference a heavy preheat tip makes. Whether you are cutting scrap beams, dismantling farm equipment, or performing facility maintenance, this tip delivers the heat and precision you need to get the job done right the first time.
