0816019880 - ESAB Twin Wire Contact Jaw 2.5-3.0mm for SAW Heads

ESAB 0816019880 Contact Jaw Twin 2.5-3.0mm Overview

The ESAB 0816019880 is a specialized Contact Jaw designed for Twin Wire Submerged Arc Welding (SAW) applications. Engineered by ESAB, a global leader in welding and cutting equipment, this component plays a critical role in the electrical transfer system of automatic welding heads, such as the renowned A2 and A6 series. In twin-wire configurations, where deposition rates are significantly increased to boost productivity, the reliability of the contact system is paramount. This jaw is precision-machined to accommodate wire diameters between 2.5mm and 3.0mm, ensuring a snug interface that facilitates efficient current transfer from the power source to the consumable electrode.

Submerged Arc Welding is a heavy-duty process often utilized in the fabrication of large structures like ships, pressure vessels, and wind towers. The equipment used in these environments must withstand continuous operation at high amperages. The ESAB Contact Jaw is manufactured from a high-conductivity copper alloy that offers excellent thermal properties and wear resistance. This material selection helps dissipate the heat generated during the welding process, preventing premature softening or deformation of the jaw. By maintaining its dimensional integrity, the jaw ensures that the wire is guided accurately into the weld pool, which is essential for achieving defect-free welds in automated setups.

Replacing contact jaws is a routine part of SAW maintenance, but using genuine OEM parts like the 0816019880 ensures compatibility and performance. Generic alternatives may lack the precise tolerances required for twin-wire feeding, leading to feeding issues or unstable arcs. This specific jaw is designed to handle the unique dynamics of feeding two wires simultaneously, providing the mechanical support and electrical continuity needed for high-speed, high-deposition welding. Whether you are welding thick plate steel or surfacing components, this contact jaw is an integral part of the ESAB SAW ecosystem.

Industrial procurement specialists looking for reliable spares for their ESAB automation equipment will find the 0816019880 to be a direct fit replacement. It is supplied as a single unit, ready for installation into the contact nozzle assembly. Regular inspection and replacement of contact jaws are recommended to prevent voltage drops and ensure the welding parameters remain within specification throughout the production run.
