359C565 - ESAB A2 Multitrac SAW System with LAF 1001 and PEK Controller

Industrial Submerged Arc Welding Solution

The ESAB A2 Multitrac PEK LAF 1001 15M is a comprehensive automatic welding system designed for high-productivity submerged arc welding (SAW). This package integrates three critical components: the versatile A2 Multitrac tractor, the advanced PEK process controller, and the robust LAF 1001 DC power source, all connected via a 15-meter cable assembly to provide operational flexibility in large-scale fabrication environments.

The A2 Multitrac is a self-propelled, four-wheel-drive automatic welding machine. Its mechanical design ensures stable travel speeds, which is critical for maintaining consistent heat input and bead geometry. The tractor is modular, allowing it to be configured for single-wire, twin-wire, or even tandem welding processes depending on the specific application requirements. The 4WD system provides excellent traction, enabling the unit to climb inclines and operate reliably on curved surfaces or uneven plates.

At the heart of the control system is the PEK Process Controller. This digital interface provides the operator with precise control over all welding parameters. It features a clear display and an intuitive menu system that allows for the presetting of current, voltage, and travel speed. The PEK controller also supports heat input monitoring and can store multiple welding schedules, ensuring repeatability across shifts and different workpieces. It communicates seamlessly with the power source to regulate the arc dynamically.

The power behind the system is the LAF 1001, a three-phase, fan-cooled DC welding power source. Engineered for heavy industrial use, it delivers a rated output of 1000 Amps at 100% duty cycle. This continuous power capability makes it ideal for long weld seams found in shipbuilding, wind tower manufacturing, and pressure vessel fabrication. The LAF series is renowned for its excellent arc characteristics, particularly at low voltages, which helps in achieving superior bead profiles and slag detachment.

This specific package includes a 15-meter interconnection cable set, providing ample reach between the stationary power source and the mobile tractor. This extended range is essential for working on large structures where moving the power source is impractical. The system is designed for durability and ease of maintenance, making it a staple in heavy engineering sectors.
