0810124882 - ESAB A2 SAW Twin Wire 2.0mm Consumable Kit

Technical Overview of the ESAB A2 SAW Wear Part Kit

The ESAB 0810124882 Wear Part Kit is a specialized assembly of consumable components designed for the maintenance and operation of ESAB A2 Submerged Arc Welding (SAW) heads. This specific kit is engineered for the "Twin Wire" configuration, a high-productivity process where two wires are fed simultaneously into a single molten pool. The components within this kit are precision-machined to accommodate 2.0mm (5/64") diameter welding wires, ensuring optimal electrical conductivity and mechanical guidance.

Submerged Arc Welding relies heavily on the integrity of the contact assembly to transfer high amperage current to the wire. In a twin-wire setup, the mechanical demands are doubled, and the alignment of the wires is critical for arc stability and bead profile control. This kit typically includes the essential contact jaws (or tips), wire guides, and associated hardware required to refresh the front end of the A2 welding head. Using genuine ESAB OEM parts ensures that the tolerances match the original equipment specifications, preventing issues such as micro-arcing inside the contact tube, irregular wire feeding, or misalignment that can lead to weld defects.

The A2 system, including the A2 Multitrac and A2 Tripletrac, is a workhorse in heavy fabrication industries such as shipbuilding, wind tower manufacturing, and beam fabrication. The Twin Wire process increases deposition rates significantly compared to single wire setups without the complexity of tandem heads. However, this performance is contingent on the condition of the wear parts. As the wire passes through the contact jaws, friction and electrical erosion gradually widen the bore, leading to poor electrical contact. This kit allows maintenance personnel to replace all critical wear points simultaneously, restoring the machine to factory performance levels.

Installation of the 0810124882 kit is straightforward for qualified technicians familiar with the A2 head. The materials used in these components are high-grade copper alloys selected for their balance of hardness (wear resistance) and electrical conductivity. By maintaining the correct contact tip-to-work distance and ensuring low-resistance current transfer, this wear part kit helps maximize the duty cycle and efficiency of the SAW process.
