The **YESHWELD ARC 400IJ** is a heavy-duty, modular IGBT inverter welding machine built for continuous, high-capacity industrial fabrication, structural steel construction, and heavy plant maintenance. Designed primarily for 3-phase (415V) industrial power supplies, it delivers a high output current from 30A up to 400A with an impressive high duty cycle for uninterrupted duty. The modular IGBT architecture ensures that internal components are easy to service while providing smooth arc stability, deep weld penetration, and energy efficiency. Capable of burning heavy electrode rods from 2.5 mm up to 5.0 mm (gauge 12 to gauge 6) on thick carbon steel, stainless steel, and alloy plates, the machine features adjustable Arc Force, Hot Start, anti-stick control, digital displays, and an aggressive forced-air cooling system built to handle harsh workshop environments.
