0461235881 - ESAB A6 Mastertrac Twin Wire Submerged Arc Tractor with PEK

High-Performance Automation for Heavy Fabrication

The ESAB A6 Mastertrac SAW Twin PEK is a premier solution for heavy-duty industrial welding applications requiring high deposition rates and consistent quality. Designed for the Submerged Arc Welding (SAW) process, this self-propelled tractor unit is engineered to automate long seam welds on plates, beams, and large vessels. The "Twin" configuration utilizes two wires fed simultaneously into a single weld pool, significantly increasing deposition rates compared to single-wire setups while maintaining a compact torch profile. This makes it an ideal choice for industries such as shipbuilding, bridge construction, and wind tower fabrication where throughput is critical.

At the heart of this system is the PEK process controller, a sophisticated digital interface that allows operators to pre-set and monitor all essential welding parameters with high precision. The PEK unit supports pre-programmed welding data, ensuring repeatability across shifts and reducing setup time for complex jobs. The tractor itself features a robust 4-wheel drive system with a feedback-controlled travel motor, ensuring stable movement and consistent travel speeds even on inclined workpieces or uneven surfaces. The modular design of the A6 system means that components can be easily interchanged or upgraded, providing long-term investment protection and adaptability to changing production needs.

The A6 Mastertrac is built to withstand the rigors of heavy industry. Its heavy-duty slides allow for precise vertical and horizontal adjustments of the welding head, ensuring optimal torch positioning. The twin wire setup not only improves speed but can also bridge wider gaps and provide better wetting action at the toes of the weld. By integrating the A6 Mastertrac into your production line, you achieve a significant leap in productivity, reducing manual welding fatigue and ensuring X-ray quality welds on the thickest materials.
