345P022171 - ESAB Conical MIG Nozzle NW 16mm x 75.5mm

Precision Shielding for Quality Welds

The ESAB Nozzle NW 16mm (Part Number 345P022171) is a high-performance consumable designed to ensure the integrity of your MIG/MAG welding processes. In gas metal arc welding, the gas nozzle plays a critical role in directing the shielding gas—such as Argon/CO2 mixes—over the weld pool to prevent atmospheric contamination. This specific nozzle features a Nominal Width (NW) of 16mm, providing a generous gas envelope suitable for medium to heavy-duty welding applications where consistent coverage is paramount.

With a length of 75.5mm, this nozzle is engineered to fit specific ESAB MIG torch assemblies, ensuring the contact tip is properly recessed or positioned relative to the nozzle exit. The conical shape is a preferred design for many operators as it balances gas flow efficiency with accessibility, allowing the welder to maneuver into tighter joints without sacrificing the protective gas shield. Manufactured from durable copper alloy, it offers excellent thermal conductivity to dissipate heat during prolonged welding arcs.

Regular inspection and replacement of gas nozzles are essential for maintaining weld quality. A worn or spatter-clogged nozzle can lead to turbulent gas flow, resulting in porosity or poor bead appearance. The ESAB 345P022171 is built to OEM specifications, guaranteeing a perfect fit and reliable performance for your industrial welding needs.
