0818970880 - ESAB A6S Tandem Submerged Arc Welding Head with 156:1 Gear Ratio

ESAB A6S DS 156:1 SAW Tandem Head Overview

The ESAB A6S DS 156:1 SAW Tandem Head (SKU: 0818970880) is a premium component designed for high-productivity Submerged Arc Welding (SAW) automation. As part of the modular A6 system, this head is engineered to meet the rigorous demands of heavy industry, offering a tandem wire configuration that significantly enhances deposition rates and welding speed. The unit features a specific 156:1 gear ratio, optimized to deliver the precise torque and speed required for stable wire feeding across various wire diameters and welding parameters.

The tandem configuration typically utilizes two wires fed into a single molten pool, often powered by separate power sources (e.g., DC lead and AC trail). This setup allows for independent control of penetration and deposition, making the A6S Tandem Head ideal for thick-plate fabrication where efficiency is paramount. The 156:1 gearing ensures that the wire feed motor operates within its optimal efficiency range, providing consistent feed force even when using large diameter wires or experiencing resistance in the conduit.

Constructed with durability in mind, the A6S head integrates seamlessly with ESAB's range of columns and booms, tractors, and process controllers like the PEK. Its modular nature allows for easy maintenance and reconfiguration, ensuring that the system can adapt to evolving production requirements. Whether utilized in the manufacturing of wind towers, pressure vessels, or bridge beams, the ESAB A6S DS 156:1 stands as a benchmark for reliability and performance in automated welding.
