Key Specifications Feature Typical Specification Significance Technology IGBT Inverter Makes the machine extremely compact, lightweight ($approx 4 text{ kg}$), and highly energy efficient. Welding Process MMA / ARC (Stick) Designed for welding with coated electrodes (rods) on various metals. Input Voltage $mathbf{220 text{ V} / 240 text{ V}}$ Single Phase Operates on standard household or workshop power. Usable Output Current $20 text{ A} text{ to } 160 text{ A}$ (Most common rated range) Although the model name suggests $250 text{ A}$, the highest reliable and continuously rated output is typically $140 text{ A}$ to $160 text{ A}$. Electrode Size $1.6 text{ mm}$ to $4.0 text{ mm}$ Capable of running the most common rods, including $2.5 text{ mm}$ and $3.2 text{ mm}$ for general fabrication. Duty Cycle $60%$ at $160 text{ A}$ (Common) Allows for 6 minutes of continuous welding at $160 text{ A}$ within any 10-minute period before a cool-down is required. No-Load Voltage (OCV) $mathbf{60 text{ V} text{ to } 65 text{ V}}$ A higher OCV helps with easier arc ignition (striking the arc).
