The Harris 23A90-7 (SKU: 1600910) is a premium swaged welding and brazing tip designed for heavy-duty industrial applications. Manufactured by Harris, a leader in gas apparatus, this tip is engineered to deliver a stable, high-temperature flame using Oxy-Acetylene or Oxy-Hydrogen gas mixtures. The 23A90 series is renowned for its durability and precision, featuring a one-piece copper construction that withstands high heat and harsh working environments found in shipyards, fabrication shops, and maintenance facilities.
This specific Size 7 tip is calibrated for welding steel thicknesses ranging from approximately 1/2 inch (12.7mm) to 3/4 inch (19mm). It requires the use of a Harris E-43 mixer to attach to compatible torch handles, such as the industry-standard Model 43-2 or Model 63-2. The swaged design ensures a smooth gas flow, reducing turbulence and providing a long, defined inner cone that allows operators to direct heat precisely where it is needed. This makes it an essential component for structural welding, large-scale brazing, and localized heating tasks.
Proper gas pressure settings are critical for optimal performance. For the 23A90-7, recommended oxygen and acetylene pressures typically range between 5 to 10 PSIG, depending on the specific application and hose length. The tip's robust design minimizes the risk of flashback when used with the correct mixer and safety equipment. By choosing genuine OEM Harris parts, operators ensure compatibility, safety, and maximum efficiency in their oxy-fuel processes.
