CA43A - Uniweld CA43A Harris Style Heavy Duty Cutting Attachment

Heavy-Duty Industrial Cutting Attachment

The Uniweld CA43A Cutting Attachment is a premium-grade component designed to convert compatible welding handles into powerful cutting torches. Engineered to meet the rigorous demands of industrial environments, this attachment is fully compatible with Harris-style 43-2 torch handles as well as Uniweld's own 43 series. It features a robust construction that utilizes triangular stainless steel tubes, providing exceptional rigidity and strength while minimizing weight. The head is forged from high-quality brass, ensuring resistance to heat deformation and long-term durability under thermal stress.

One of the defining technical characteristics of the CA43A is its "All Fuels" capability. This unit is designed to operate safely and efficiently with Acetylene, Propane, Propylene, and Natural Gas. The versatility is achieved through the use of specific cutting tips (sold separately) that dictate the gas mixing, typically utilizing a tip-mix system common to Harris-style equipment. This design significantly reduces the risk of flashback in the tubes, enhancing operator safety.

The attachment features a standard 90-degree head angle, ideal for the majority of manual cutting tasks. With the capacity to cut steel up to 8 inches (approx. 200mm) thick, it is suitable for heavy structural demolition, fabrication, and scrap processing. The connection mechanism employs a double O-ring seal to ensure a gas-tight fit with the handle, preventing leaks and maintaining consistent pressure. The lever is ergonomically designed for precise control of the cutting oxygen stream, allowing for clean starts and smooth cuts.

For professionals seeking a reliable replacement or upgrade for their Harris-style equipment, the Uniweld CA43A delivers OEM-level performance and compatibility. It integrates seamlessly into existing oxy-fuel setups, requiring only the appropriate 6290-style tips to match the chosen fuel gas.
