AICO PROFESSIONAL MMA-300 INVERTER WELDING MACHINE

Electrical & Power Specs

• Input Voltage: $220\text{V} \pm 15\%$, Single Phase ($50/60\text{Hz}$).

• Maximum Output Current: 300 Amps.

• Current Adjustment Range: $20\text{A}$ to $300\text{A}$ regulated via the front control dial.

• Duty Cycle: 60% at 300A (allowing for sustained, high-intensity commercial use).

• No-Load Voltage ($U_0$): ~63V to 70V (engineered for easier, rapid arc ignition).

• Efficiency Rating: $\ge 85\%$.

Welding Capabilities

• Welding Type: MMA (Manual Metal Arc) / Shielded Metal Arc Welding (SMAW) / Stick Welding.

• Compatible Electrode Diameters: Handles welding rods ranging from 1.6mm up to 5.0mm.

• Material Suitability: Ideal for achieving deep penetration on a wide span of metals, including mild steel, carbon steel, stainless steel, and cast iron.

Interface & Safety Features

• Digital Display Panel: A prominent LED Amperage meter providing real-time output monitoring for precise heat control.

• Stepless Control Knob: Located adjacent to the screen for fine-tuning current settings.

• Dinse Style Connectors: Heavy-duty twist-lock positive (+) and negative (-) output terminals on the bottom front face for secure cable connections.

• Thermal Overload Protection: Internal sensors that automatically trip or flag fault alerts to prevent core damage from over-heating or over-current spikes.

• Enclosure & Portability: Housed in an impact-resistant red steel chassis with reinforced rubber/plastic armor molding on the corners, complete with a top-mounted non-slip carrying handle.
