6290A-2 - Harris Compatible 6290A Size 2 Acetylene Cutting Tip

Precision Harris-Style Replacement Cutting Tip

The Harris Style 6290A-2 Cutting Tip is a premium-quality generic replacement component designed to meet the rigorous demands of industrial oxy-acetylene cutting. Engineered to replicate the performance specifications of the original Harris 6290 series, this tip features a flat seat design that ensures a secure and leak-proof connection with all standard Harris-style cutting attachments and torches. The "A" designation indicates its specific optimization for Acetylene gas, utilizing a one-piece construction that is standard for this fuel type to ensure flame stability and safety.

This specific model is a Size 2, which is calibrated to deliver a cutting oxygen stream capable of severing mild steel up to 2 inches (50.8 mm) in thickness. The tip utilizes a medium preheat pattern, which provides a balanced thermal output suitable for a wide range of applications. This preheat level is sufficient to quickly bring the steel to ignition temperature without overheating the kerf edge, resulting in cleaner cuts with less slag accumulation. The internal geometry of the tip is precision-drilled to maintain a laminar oxygen flow, which is critical for maintaining cut straightness and quality over the lifespan of the consumable.

Constructed from a high-conductivity copper alloy, the 6290A-2 effectively dissipates heat away from the tip face, reducing the risk of overheating and flashback during prolonged cuts. It is an essential consumable for fabrication shops utilizing Harris equipment that require reliable, consistent performance for medium-heavy plate cutting. Operators should ensure their oxygen pressure regulators are set appropriately (typically 40-50 PSIG for a Size 2 tip) to achieve optimal cutting speeds and quality.
