SAW power source allows switching between AC, DC without stopping welding process

ESAB Welding & Cutting Products has introduced the Aristo 1000 AC/DC power source for SAW. The inverter power source, which can be connected to three-phase input voltage supply (from 380 to 575 V at 50 or 60 Hz), uses patent-pending technologies to deliver high-quality welding with low power consumption, the manufacturer states.

Users can switch between AC and DC without stopping the welding process. Using the Bead Profile Modeling™ function, the operator can control the AC frequency, balance, and offset 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 designed for heavy-duty industrial environments and is suitable for welding wind tower structures, nuclear components, beams, bridge components, trailer beams, excavator components, and for general fabrication.
