0004450613 - ESAB PSF 405/505 Standard Gas Nozzle

Optimize Your Shielding Gas Coverage

When it comes to MIG welding, the condition of your front-end consumables directly impacts the quality of your bead. The ESAB 0004450613 Gas Nozzle is the genuine replacement part you need for your PSF 405 or PSF 505 welding gun. Designed to handle the heat of heavy-duty welding, this nozzle directs your shielding gas precisely where it's needed—over the molten weld pool—to prevent contamination and porosity.

Over time, spatter buildup and heat can degrade your nozzle, causing uneven gas flow and frustrating weld defects. Swapping out your old, battered nozzle for a fresh ESAB replacement restores that smooth, consistent gas coverage you rely on. Whether you are welding mild steel, stainless, or aluminum, having a clean and dimensionally correct nozzle is the first step toward a professional-looking finish.

This nozzle features a robust copper construction that resists spatter adhesion better than generic alternatives, making it easier to clean and longer-lasting. It screws on securely and fits perfectly with your existing contact tips and diffusers, so you can get back to welding with confidence. Don't let a bad nozzle ruin your arc; keep your PSF torch performing at its best with genuine ESAB parts.
