0258006580 - ESAB 2.0mm M16 Contact Nozzle for SAW/MIG

Technical Overview of the ESAB 0258006580 Contact Nozzle

The ESAB 0258006580 is a specialized contact nozzle designed for industrial welding applications requiring precision and durability. Engineered to accommodate a 2.0mm welding wire, this component is critical for maintaining consistent electrical transfer from the welding power source to the filler metal. The nozzle features a robust M16 thread, a specification often associated with heavy-duty automatic welding heads and Submerged Arc Welding (SAW) equipment, ensuring a mechanical connection that can withstand the vibration and thermal expansion cycles inherent in high-amperage processes.

Manufactured from a high-purity copper alloy, this contact nozzle is optimized for thermal management and electrical conductivity. In automated welding environments, such as beam fabrication or pipe welding, the stability of the arc is directly influenced by the quality of the contact tip. The 2.0mm bore is precision-drilled to tight tolerances, minimizing micro-arcing inside the tip which can lead to premature failure or wire burn-back. The M16 threaded base provides a large contact area for current transfer and secure mounting, reducing the risk of loosening during operation.

This component is identified by the internal SKU ESB0258006580 and is a direct OEM replacement part. It is essential for maintenance personnel and welding engineers to verify the thread pitch and wire diameter requirements of their specific torch setup before installation. The nozzle is compatible with specific ESAB automatic welding heads, often found in the A2 or A6 series or similar heavy-duty configurations. Proper maintenance and timely replacement of the contact nozzle are vital for ensuring weld quality and preventing defects such as porosity or lack of fusion caused by unstable arc characteristics.
