0460504880 - ESAB PEK Digital Process Controller for A2/A6 Automats

Advanced Automation Control with ESAB PEK

The ESAB PEK Control Box (SKU: 0460504880) is a premier process controller designed for heavy-duty automatic welding applications. Engineered to integrate seamlessly with ESAB's A2 and A6 welding heads, this unit provides precise regulation for both Submerged Arc Welding (SAW) and Gas Metal Arc Welding (GMAW). It serves as the brain of the welding system, communicating via a robust CAN-bus protocol to ensure instant and accurate data exchange between the power source, the travel carriage, and the wire feed unit.

Technically, the PEK is built to handle the rigors of industrial environments while offering sophisticated control logic. It operates on a 42V AC input, typically supplied directly from the welding power source (such as the LAF or TAF series). The unit features encoder feedback loops that monitor wire feed speed and travel speed in real-time, adjusting output to maintain strict adherence to preset parameters. This ensures consistent weld quality, penetration, and bead profile, which is critical in sectors like beam fabrication, pipe mills, and pressure vessel manufacturing.

The interface is designed for efficiency, featuring a clear LCD screen that displays parameters in user-friendly text menus. Operators can pre-set current, voltage, and travel speed, and the system allows for the storage of up to 255 distinct welding parameter sets. This memory function is invaluable for facilities handling diverse workpieces, allowing for rapid changeovers without the need for manual recalibration. The PEK also supports heat input monitoring when equipped with the appropriate sensors, aiding in compliance with strict WPS requirements.

Installation is straightforward for existing ESAB automation users, making it an excellent choice for upgrading older analog control systems (like the PEH or PEG) to modern digital standards. Its compatibility extends to the Aristo 1000 AC/DC, enabling advanced AC wave control for specialized SAW applications.
