OVERVIEW

Big Heat for Big Jobs

When you are staring down a piece of 3/8-inch steel plate that needs to be joined, you can't mess around with undersized tips. You need the Harris Style 23A90-7. This is a beast of a welding tip, designed to dump serious heat into your workpiece so you can get full penetration and a solid bead. It's a direct replacement for the standard Harris 23A90-7, meaning it fits right onto your existing rig without any hassle.

If you are running a Harris 43-2 handle or an old-school Model 85, this tip is your go-to for heavy fabrication. It screws directly into your D-85 mixer. The copper construction stands up to the high heat of oxy-acetylene welding, and the orifice is precision-drilled to give you that perfect neutral flame you're looking for. No sputtering, no weird flame shapes—just a clean, hot cone that lets you control the puddle exactly how you want.

Why pay top dollar for the brand name when this tip does the exact same job? Whether you are bending heat, brazing heavy castings, or welding structural steel, the #7 tip gives you the BTUs you need. Make sure your regulators are set correctly for the higher flow rate this tip demands, and you'll be laying down dimes in no time. It's a must-have for any welder's toolbox who deals with heavy iron.

Quick Setup Guide

  • Check Your Mixer: Ensure you have a D-85 or compatible mixer.
  • Set Your Pressure: Size 7 tips need more gas. Check your chart (approx 5-8 PSI Acetylene, 5-10 PSI Oxygen).
  • Clean Your Tip: Keep the orifice clean with a tip cleaner to maintain flame shape.

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.
