NIKO ARC 400J Heavy Duty 3-Phase Inverter Welding Machine

Niko Arc 400J: The Industrial Standard for Heavy Fabrication

When standard single-phase power isn’t enough, the Niko Arc MMA 400 Model J provides the raw power required for heavy-duty industrial applications. As a Three-Phase (415V) machine, it offers a level of arc consistency and penetration that smaller machines simply cannot match.

Engineered for a full day Productivity

The “J” Model is built around a Double IGBT Module system. This isn’t just a marketing term—it means the machine uses two power modules to share the load, significantly reducing heat stress and increasing the lifespan of the internal components under high-amperage use.

Key Performance Benefits:

• Continuous 5mm Rod Support: Designed specifically for thick-plate welding, it can run 5.0mm electrodes all day without tripping the thermal protection.

• Precision Arc Control: Features a front-panel Arc Force adjustment knob, allowing you to fine-tune the “dig” of the arc based on the thickness of the metal.

• Built-in VRD Safety: The Integrated Voltage Reduction Device ensures operator safety by keeping the open-circuit voltage (OCV) low when the machine is on but not actively welding.

• High Power Factor (0.93): Maximizes electricity usage efficiency, reducing power wastage and lowering operating costs on large-scale job sites.

  Best For:
• Heavy Structural Steel: Beams, columns, and large frames.

• Industrial Maintenance: Repairing heavy earthmoving equipment and factory machinery.

• Professional Fabricators: Ideal for workshops that require a dedicated, high-output station.
