0460513881 - ESAB LAF 1001M Submerged Arc Welding Power Source 1000A

Heavy-Duty Submerged Arc Power Source

The ESAB LAF 1001M is a premier three-phase DC power source engineered specifically for high-productivity automated welding applications. Designed to serve the rigorous demands of heavy industry, this unit excels in Submerged Arc Welding (SAW) as well as high-deposition MIG/MAG processes. With a robust input configuration of 440/550V 3-Phase, the LAF 1001M ensures stable and powerful output required for deep penetration and multi-pass welding on thick materials.

At the core of the LAF series is ESAB's commitment to arc stability and process control. The machine provides excellent welding characteristics throughout its entire current range, ensuring consistent bead profiles and metallurgical quality. It is specifically designed to integrate seamlessly with ESAB's range of automatic welding heads and tractors, such as the A2 and A6 series, making it a cornerstone for shipbuilding, wind tower fabrication, and pipe mill operations. The power source communicates effectively with advanced process controllers like the PEK and PEH, allowing for precise digital setting and monitoring of welding parameters.

Reliability is paramount in continuous production environments. The LAF 1001M features a heavy-duty, fan-cooled architecture that manages thermal loads effectively, allowing for high duty cycles—typically rated for continuous operation at high amperages. The unit also includes mains voltage compensation, which maintains a steady welding current even if the input power fluctuates, preventing defects and rework. Its rugged steel casing protects internal components from dust, moisture, and mechanical impact common in large-scale fabrication shops.

Whether utilized for single-wire or multi-wire SAW applications, the LAF 1001M delivers the power and precision necessary to maximize deposition rates and minimize downtime. It represents a strategic investment for facilities aiming to optimize their automated welding throughput.
