Niko Arc 315W: The Dual-Phase Industrial Workhorse
The Niko Arc 315W is engineered for high-demand environments where power versatility is a necessity. Unlike standard single-phase units, the Model W allows for seamless switching between single-phase (220V) and two-phase (380V/440V) inputs, making it the preferred choice for construction sites and heavy fabrication workshops across India.
Key Benefits for Professionals:
Smart Dual Voltage: Automatically adapts to your power source, preventing circuitry damage from incorrect voltage inputs.
IGBT Inverter Tech: Provides a stable, spatter-free arc, even when using low-quality electrodes or working in areas with voltage fluctuations.
Built-in VRD (Voltage Reduction Device): Enhances operator safety by reducing the open-circuit voltage when the machine is idle—essential for working in damp or hazardous conditions.
Advanced Thermal Management: Large internal fans and an IP21S rating ensure the machine remains cool during prolonged heavy-duty welding cycles.
