The **YESHWELD ARC 400M** is an industrial-grade, high-capacity arc welding machine engineered for heavy-duty fabrication, structural metalwork, and continuous production environments. Built with advanced IGBT inverter technology, it provides high energy efficiency, exceptional arc stability, and deep weld penetration while operating across a wide output range of 20A to 400A. The machine is capable of burning thick electrodes (ranging from 2.5 mm up to 5.0 mm continuously) on mild steel, stainless steel, and alloy plates. It includes key industrial safety features such as thermal overload protection, arc force control, anti-stick technology, digital current meters, and high-velocity forced-air cooling to maintain peak performance during long, high-amperage welding cycles.
