OVERVIEW

Get Better Gas Coverage with the ESAB PM-359 Nozzle

If you are running an ESAB or L-Tec MIG gun and noticing porosity in your welds or excessive spatter buildup on your front-end parts, it might be time to swap out your nozzle. The ESAB PM-359 (Part #2228184) is a heavy-duty gas nozzle designed to keep your shielding gas flowing smoothly and your welds looking clean. With a 1/2-inch (0.50") bore, this nozzle is the "goldilocks" size for most shop applications—large enough to provide a wide blanket of gas for good coverage, but narrow enough to let you see the puddle and get into corners.

We know that in a busy shop, nozzles take a beating. They get hammered to remove spatter, overheated during long welds, and dropped on the concrete. That’s why ESAB builds the PM-359 out of durable copper alloy. It resists spatter adhesion better than cheaper alternatives and handles the heat without deforming quickly. A fresh nozzle ensures that your shielding gas exits the gun in a smooth column, protecting your molten pool from oxygen and nitrogen that cause weak, hole-filled welds.

This nozzle is a direct fit for guns requiring the PM-359 style. Whether you are welding mild steel, stainless, or aluminum, having a clean, unblocked nozzle is the first step to a quality bead. The 1/2-inch opening is particularly great for short-circuit MIG and spray transfer on medium-thickness materials. Don't let a clogged or battered nozzle ruin your work; keep a few of these 2228184 nozzles in your toolbox to ensure you are always ready to lay down perfect beads.

Why Welders Choose This Nozzle:

  • Perfect Fit: Designed specifically for your ESAB/L-Tec gear, ensuring no gas leaks at the seat.
  • Clean Welds: The 1/2" bore provides the right amount of gas coverage for standard wire sizes like .030" and .035".
  • Durable: Tough copper construction stands up to heat and daily abuse.
  • Less Downtime: Smooth finish makes spatter removal easier, keeping you welding longer between cleanings.

FAQ

The bore size is 0.50 inches (1/2 inch), indicated by the "50" in the product description.

It is manufactured from a high-quality copper alloy designed for heat resistance and durability.

No, it is specific to guns that accept the PM-359 series nozzles, often found on certain ESAB and legacy L-Tec MIG guns.

A 1/2-inch bore offers a balance of good gas coverage and joint accessibility, suitable for most standard welding applications.

While you can physically use it, gas nozzles are typically removed or replaced with a thread protector for self-shielded flux-cored welding to prevent spatter buildup inside the nozzle.

Replace the nozzle when the orifice becomes deformed, heavily spattered beyond cleaning, or if the insulator is damaged, as this disrupts gas flow.

The PM-359 series typically features a specific connection style (often slip-on with an insulator or threaded depending on the specific gun sub-model); check your gun's manual for the exact attachment method.

A 1/2 inch nozzle is versatile and works well with common wire sizes ranging from 0.023" to 0.045".
