0258006583 - ESAB 4.0mm M16 Contact Nozzle for SAW

Reliable Current Transfer for Heavy Fabrication

When you are running heavy sub-arc passes, the last thing you need is a contact tip that overheats or feeds wire poorly. This ESAB Contact Nozzle is built for the serious demands of 4.0mm wire welding. With a solid M16 thread, it locks tight into your torch or welding head, ensuring that the massive current needed for SAW gets exactly where it needs to go—into the wire. The 4.0mm bore is smooth and precise, preventing the wire from snagging or wandering, which helps keep your arc centered and your weld bead straight.

We know that in heavy fabrication, downtime is the enemy. This nozzle is crafted from durable copper alloy designed to handle high heat and high amps without melting back or keyholing prematurely. Whether you are welding thick plate, pressure vessels, or structural beams, having a fresh, high-quality contact nozzle ensures your machine runs at peak efficiency. The M16 thread makes changeouts simple and fast, so you can get back to welding with minimal interruption.

This isn't just a generic replacement; it's an ESAB-engineered part meant to work seamlessly with your ESAB automatic equipment. Using the correct size nozzle for your 4.0mm wire is crucial for electrical contact. A loose fit causes arcing inside the tip, while a tight fit causes feed motor strain. This nozzle hits the sweet spot, giving you smooth delivery and a stable arc, pass after pass.
