Key Specifications (MMA-500T) Feature Specification (Industrial Standard) Impact on Use Welding Process MMA (Stick) Welding Capable of welding the thickest plates using large-diameter electrodes. Technology Advanced IGBT Inverter Full digital design ensures high efficiency, portability, and an extremely stable arc required for high-amperage welding. Max Output Current 500 Amps (DC) Maximum Power: Allows for the use of electrodes up to $6.0 \text{ mm}$ for deep penetration and welding very thick materials. Input Voltage 3P AC $380\text{V} – 415\text{V}$ (Three-Phase) Crucial: Requires an industrial power supply or a large three-phase generator (often $15 \text{ KVA}$ or higher). Rated Duty Cycle $60\%$ @ $500 \text{A}$ (Common) An excellent duty cycle for a machine this size, meaning it can weld for 6 minutes continuously at full power within a 10-minute cycle. Rated Input Power $\approx 25 \text{ kVA}$ (Required Input) Indicates the high power consumption necessary for such output. Welding Machine
