0461234880 - ESAB A2 Multitrac A2TF MIG Tractor with PEK

Advanced Automation with the ESAB A2 Multitrac GMAW

The ESAB A2 Multitrac GMAW 2WD PEK (SKU: 0461234880) represents a pinnacle in modular automatic welding technology. Designed for heavy-duty industrial applications, this self-propelled welding tractor is configured specifically for Gas Metal Arc Welding (GMAW), providing a robust solution for long, continuous welds where consistency and deposition rates are critical. The unit is built around the reliable A2 tractor platform, featuring a 2-wheel drive system that ensures stable movement across workpieces, even when operating on slight inclines or uneven surfaces.

At the heart of this system is the PEK Process Controller. This advanced digital interface allows operators to pre-set and strictly control all vital welding parameters, including travel speed, wire feed speed, voltage, and amperage. The PEK controller supports a menu-based system that is intuitive for welding engineers and operators alike, enabling the storage of welding data and ensuring repeatability across multiple shifts or workpieces. The integration of the PEK controller transforms the A2 Multitrac from a simple mechanical carriage into a sophisticated welding robot capable of delivering X-ray quality welds.

The mechanical design of the A2TF (GMAW version) includes a heavy-duty wire feed mechanism capable of handling high duty cycles. It supports a wide range of wire diameters, from 0.8mm solid wires up to 2.4mm flux-cored wires, making it versatile for various structural steel, shipbuilding, and bridge construction tasks. The feedback-controlled wire drive motor ensures that wire feed speed remains constant, compensating for any resistance in the liner or torch cable, which is essential for maintaining a stable arc in automated processes.

This unit is designed to operate with ESAB's high-performance power sources, such as the Aristo or LAF series, creating a synchronized welding system. The modularity of the A2 Multitrac series also means that components can be serviced or swapped with relative ease, minimizing downtime in production environments. By automating the travel and feed functions, the A2 Multitrac GMAW significantly increases arc-on time compared to manual application, delivering a rapid return on investment for fabricators dealing with long linear joints.
