0258006583 - ESAB 4.0mm M16 Contact Nozzle for SAW

High-Performance ESAB Contact Nozzle for Submerged Arc Welding

The ESAB Contact Nozzle 4.0mm M16 (Part Number: 0258006583) is a critical consumable component engineered for precision and durability in automated welding environments. Specifically designed to accommodate 4.0mm welding wire, this nozzle features a robust M16 thread that ensures a secure mechanical and electrical connection to the welding head. Manufactured from high-grade copper alloy, it provides the exceptional electrical conductivity required to transfer high amperage currents efficiently to the electrode wire, a staple requirement in Submerged Arc Welding (SAW) processes.

In industrial manufacturing, the integrity of the contact nozzle directly influences arc stability and weld quality. This ESAB nozzle is machined to tight tolerances, ensuring concentricity between the bore and the outer body. This precision minimizes wire drag and promotes smooth feeding, which is vital for maintaining consistent bead profiles in long, continuous welds often found in structural steel, pipe manufacturing, and shipbuilding. The M16 threading is standard for heavy-duty contact jaws and extensions, allowing for quick replacement during maintenance intervals without compromising the alignment of the welding system.

Thermal management is another key attribute of this component. The mass and material composition of the nozzle allow it to withstand the intense heat generated during the SAW process, resisting deformation and wear at the exit point. By maintaining its geometry over longer periods, it reduces downtime associated with frequent consumable changes. This product is compatible with various ESAB automatic welding heads, making it a versatile stock item for facilities utilizing ESAB's extensive range of automation equipment.
