0461233880 - ESAB A2 Multitrac SAW Tractor with PEK Controller

ESAB A2 Multitrac SAW Tractor with PEK Controller

The ESAB A2 Multitrac SAW PEK (SKU: 0461233880) is a premier automatic welding tractor designed for high-efficiency Submerged Arc Welding (SAW). Engineered for the rigorous demands of heavy fabrication, this machine combines mechanical robustness with advanced digital control. At its core is the A2 tractor unit, featuring a powerful 4-wheel drive system that ensures stable and consistent travel speeds across various workpiece geometries. This stability is critical for maintaining uniform weld bead profiles in long-seam applications such as beam fabrication, bridge building, and shipbuilding.

The unit is equipped with the PEK process controller, ESAB's sophisticated digital interface for automation. The PEK controller allows operators to preset all essential welding parameters, including current, voltage, and travel speed, before the arc is struck. This eliminates guesswork and ensures strict adherence to Welding Procedure Specifications (WPS). The controller features a clear display with an intuitive menu system, supporting multiple languages and offering memory slots to save and recall successful weld schedules. Furthermore, the PEK system provides real-time feedback and monitoring of heat input, a vital metric for maintaining the metallurgical integrity of high-strength steels.

Mechanically, the A2 Multitrac is designed for versatility. While configured here for Submerged Arc Welding, the modular design allows for conversion to MIG/MAG processes if required. The wire feed mechanism is robust, capable of handling wire diameters typically ranging from 1.6mm to 4.0mm in single-wire configurations. The tractor can also be adapted for twin-wire welding to further increase deposition rates. The entire unit is relatively lightweight for its class, allowing it to be moved easily by a single operator from one joint to another. It integrates seamlessly with ESAB's range of power sources, including the LAF (DC) and TAF (AC) series, providing a complete, synchronized welding system.
