OVERVIEW

Heavy-Duty Harris Style Welding Tip

The GEN23A90-7 is a premium aftermarket replacement welding tip designed to replicate the performance specifications of the Harris 23A90-7. Engineered for heavy-duty industrial applications, this tip is manufactured from high-grade copper alloy, ensuring excellent thermal conductivity and resistance to heat deformation during prolonged use. It is specifically calibrated for Oxy-Acetylene or Oxy-Hydrogen gas mixtures, providing a stable and consistent flame profile essential for high-quality welds.

This size #7 tip is capable of welding steel plates with thicknesses approximating 3/8 inch (9.5mm) to 1/2 inch (12.7mm), depending on operator technique and joint configuration. It features a swaged design which streamlines gas flow and minimizes turbulence, resulting in a clean, hot flame cone. The tip base is machined to precise tolerances to ensure a perfect seal with compatible mixers, such as the Harris D-85 or H-16-2E, preventing dangerous gas leaks and flashbacks.

Integration is seamless with standard Harris equipment. The 23A90 series tips are designed to thread into the mixer assembly which then attaches to torch handles like the Model 43-2, 63-2, or the Model 85. This modularity allows for quick changeovers between tip sizes without replacing the entire torch setup. Industrial maintenance teams and fabrication shops will appreciate the reliability and cost-effectiveness of this generic alternative.

FAQ

This tip fits Harris style handles such as the 43-2, 63-2, and 85, but it requires a mixer (typically the D-85 or H-16-2E) to attach to the handle.

A size #7 welding tip is generally rated for welding steel thicknesses between 3/8 inch (9.5mm) and 1/2 inch (12.7mm).

No, the 23A90 series is designed specifically for Acetylene or Hydrogen. For Propane or Natural Gas, you should use a tip designed for alternate fuels (often with a recessed tip end) to prevent flame instability.

While settings can vary by equipment condition, a starting point for a size #7 tip is approximately 5-8 PSIG for Acetylene and 5-10 PSIG for Oxygen. Always consult the specific tip chart for your torch.

Yes, the 23A90 style tip is a screw-in tip that requires a separate mixer assembly (like the D-85) to connect to the torch handle.

Use a standard tip cleaner set. Find the wire size that fits snugly into the #7 orifice without forcing it, and file gently to remove carbon buildup and splatter.

No, this is a high-quality generic or aftermarket replacement part designed to be fully compatible with Harris equipment.

Popping usually indicates the tip is overheating, the gas pressure is too low (starving the tip), or the tip is loose. Check your connections and ensure your pressures are set high enough for a size #7 tip.
