23A90-5 - Harris Style 23A90-5 Acetylene Welding Tip Size 5

Harris Style 23A90-5 Welding Tip: Technical Overview

The Harris Style 23A90-5 Welding Tip is a precision-engineered aftermarket component designed to meet the rigorous demands of industrial welding and brazing. As a direct replacement for the original Harris 23A90-5, this tip offers exceptional compatibility with standard Harris oxy-fuel equipment, specifically fitting the widely used 43-2 and 85 series torch handles when equipped with the appropriate mixers such as the E-43, D-85, or H-16-2E. This compatibility ensures that fabrication shops and maintenance departments can maintain their equipment without sourcing expensive OEM parts, while still achieving professional-grade results.

Manufactured from high-purity copper, the 23A90-5 is built to withstand the intense thermal cycles inherent in oxy-acetylene welding. The copper construction not only provides structural integrity but also facilitates rapid heat dissipation, preventing the tip from overheating during extended operation. This thermal management is critical for maintaining a stable flame profile and preventing flashbacks. The tip features a carefully swaged orifice, size #5, which is calibrated to deliver a consistent flow of gas. This precision allows for a neutral flame that is easy to adjust and control, providing the welder with the accuracy needed for high-quality bead deposition and penetration.

Designed exclusively for use with Acetylene or Hydrogen fuel gases, the 23A90-5 leverages the high flame temperature of these fuels to effectively weld mild steel and braze various metals. The size #5 designation typically correlates to a welding capability for material thicknesses ranging from approximately 1/8 inch to 3/16 inch (3.2mm to 4.8mm), making it a versatile choice for medium-duty fabrication tasks. It is important to note that this tip is not suitable for alternative fuels such as Propane, Propylene, or Natural Gas, as these require a different injector design to maintain flame stability. Using the correct fuel gas is paramount for safety and weld quality.

In addition to its primary welding function, this tip is also effective for localized heating applications where a cutting torch might be too aggressive. Its focused flame allows for the heating of nuts, bolts, and small metal sections for bending or straightening. Maintenance of the tip is straightforward; standard tip cleaners can be used to remove carbon deposits and spatter from the orifice, ensuring a long service life. By choosing the Harris Style 23A90-5, professionals invest in a reliable, high-performance tool that supports efficient workflow and superior craftsmanship in metal joining processes.
