0461235890 - ESAB A6 Mastertrac Automatic SAW Tractor with PEK Control

Precision Automation for Heavy Industry

The ESAB A6 Mastertrac SAW PEK is a premier solution for high-productivity automated welding applications. Designed as a self-propelled, four-wheel-drive automatic welding machine, the Mastertrac is engineered to handle the rigors of heavy fabrication environments such as shipbuilding, bridge construction, and pressure vessel manufacturing. The unit utilizes the renowned A6 welding head, a modular system known for its durability and capacity to handle high currents and heavy wire diameters, ensuring deep penetration and superior weld integrity.

At the core of this system is the PEK process controller. This advanced digital unit provides the operator with precise control over all critical welding parameters. It features a clear menu system and the ability to store up to 255 different parameter sets, allowing for rapid changeovers between different welding procedures without the risk of manual setup errors. The PEK controller monitors the welding process in real-time, adjusting wire feed speed and voltage to maintain a stable arc and consistent bead profile, which is critical for meeting stringent code requirements in structural applications.

The mechanical design of the A6 Mastertrac ensures stability and traction. The four-wheel drive system ensures consistent travel speeds, which is directly correlated to heat input and weld quality. The tractor can operate directly on the workpiece or be guided by a rail system for perfectly straight seams. Its heavy-duty slides allow for easy manual adjustment of the torch position, ensuring the arc is always focused exactly where it is needed. For industrial operations seeking to maximize deposition rates and minimize downtime, the A6 Mastertrac SAW PEK represents a significant investment in efficiency and quality assurance.
