23A90-2 - Harris Style 23A90-2 Oxy-Acetylene Welding Tip, Size 2

Technical Overview of the Harris Style 23A90-2 Welding Tip

The GEN23A90-2 is a precision-engineered aftermarket welding tip designed to replicate the performance and specifications of the standard Harris 23A90-2 tip. Manufactured from high-grade copper alloy, this tip ensures superior thermal conductivity and resistance to heat deformation during prolonged welding operations. It is specifically calibrated for use with Oxy-Acetylene fuel gas systems, providing a neutral, stable flame essential for high-quality metallurgy.

This size #2 tip is swaged to produce a focused flame cone, making it suitable for welding mild steel ranging from 1/16 inch to 1/8 inch (1.6mm to 3.2mm) in thickness. The internal geometry is machined to minimize turbulence in the gas flow, ensuring consistent pressure and flame characteristics. It requires an oxygen and fuel pressure setting of approximately 3-5 PSIG for optimal operation, matching the standard parameters for Harris equipment.

Compatibility is a key feature of the GEN23A90-2. It is designed to fit a variety of Harris torch handles and mixers. Specifically, it mates perfectly with the Harris 85 handle and the 43-2B handle (part of the 43 series). It is also compatible with mixers such as the D-85 and E-43. This versatility makes it an essential consumable for industrial maintenance, repair, and fabrication shops utilizing Harris-style oxy-fuel apparatus. The tip connects via a threaded coupling nut (typically supplied with the mixer or sold separately) ensuring a gas-tight seal to prevent leaks and backfires.

In industrial MRO environments, having reliable consumables is critical. This tip undergoes rigorous quality control to ensure the orifice size (Drill Size #62 equivalent) is accurate, providing the welder with predictable heat output and puddle control. Whether used for fusion welding, brazing copper pipes, or general heating applications, this component delivers professional-grade results.
