The MIG-400 Inverter Welding Machine is a robust, high-amperage welding unit designed for heavy-duty industrial, fabrication, and large-scale workshop applications. The “400” in the name signifies its 400 Amp maximum welding current, while “MIG” means it’s primarily a Gas Metal Arc Welding machine. The “Inverter” technology makes it far more compact, efficient, and capable of multi-process welding compared to older transformer-based welders.
