The NBM-500 is a true industrial workhorse — full-bridge IGBT inverter with 100% duty cycle at 500A (40°C ambient), designed for non-stop production in shipyards, steel structure fabrication, and heavy machinery manufacturing.
Five welding modes in one machine: Pulse MIG for aluminum (5083/6061), Synergic MIG for carbon steel, Standard MIG/MAG, MMA stick, and Lift TIG. Supports 1.0mm, 1.2mm, and 1.6mm wire diameters with a separate 4-roller enclosed wire feeder. IP23 rated with Class H insulation for the toughest environments. EU CE certified.
