PRODUCT & PRINT SPOTLIGHT Submerged Arc Welding Power Source Useful for Wind Tower Fabrication The Aristo 1000 AC/DC power source for submerged arc welding can be connected to a three-phase voltage supply from 380 to 575 V at 50 or 60 Hz. It uses patent-pending technologies to deliver good welding performance with the lowest power consumption. The product also allows the user to switch between AC and DC without stopping the welding process. This function minimizes downtime and maximizes weld quality as the user does not have to stop and restart when changing currents. Using the Bead Profile Modeling™ function gives the operator control over the AC frequency, balance, and offset. This allows the user to optimize penetration profile, heat input, deposition rate, arc stability, and stirring effect. Two units can be connected in synchronized parallel mode to deliver more welding current. The machine is useful for welding wind tower structures; nuclear, bridge, and excavator components; beams; and general fabrication. It features Cable Boost™ technology, which stores energy and instantly delivers up to 450% more energy when needed. The product can be controlled by a remote function. It is designed to be used in installations where long welding cables are necessary. The cooling fan only runs during welding. For an automated submerged arc welding package, combine the inverter with the Column and Boom system and Spoolarc 81 wire.
