998894 - ESAB #10 MIG Gun Nozzle Assembly for ST-23 Torches

Keep Your ESAB Torch Running Smoothly

If you are running an ESAB ST-23 or ST-23A MIG gun, you know these torches are built like tanks. But even the toughest gear needs fresh consumables to lay down quality beads. The ESAB 998894 Nozzle Assembly #10 is the direct replacement you need to keep your shielding gas flowing smoothly and your welds porosity-free. This isn't just a piece of copper tubing; it's a genuine ESAB assembly designed to fit your specific torch handle perfectly, ensuring you don't struggle with cross-threading or loose fits that can ruin a good day of welding.

The "#10" size refers to the 5/8-inch opening at the tip. This is arguably the most versatile size for general MIG welding. It’s wide enough to give you great gas coverage when you're cranking up the heat for spray transfer on thick steel, but it's not so huge that you can't see your puddle or get into tighter joints. The heavy-duty copper construction resists spatter buildup better than cheap knock-offs, meaning you spend less time banging your torch against the table and more time burning wire. When spatter does stick, the smooth finish makes it easier to ream out or chip off with your welpers.

Why does a fresh nozzle matter? Over time, a battered nozzle with a jagged edge or heavy spatter buildup creates turbulence in your shielding gas. Instead of a smooth stream protecting your weld, you get a swirling mess that sucks in air. That leads to pinholes and weak welds. By swapping out your old, beat-up nozzle for a fresh 998894, you restore that clean, laminar gas flow. It also includes the proper insulation to keep the nozzle electrically cold, preventing those annoying accidental arcs if you touch the workpiece. Keep a few of these in your toolbox so you're never caught off guard in the middle of a critical job.

Built for the Daily Grind

We know that in the shop, tools take a beating. This nozzle assembly is designed to handle the heat of high-amperage welding without melting or warping. Whether you are fabricating structural steel, repairing heavy equipment, or doing production MIG work, this nozzle stands up to the abuse. Don't compromise your weld quality with worn-out parts—grab a genuine ESAB replacement and keep your arc stable and your puddle clean.
