Edon ARC-500S inverter welding machine

echnical Specifications

• Welding Type: MMA / Stick (often marketed with intelligent inverter/IGBT features).

   

• Input Voltage: Single Phase 220V ($\pm 10\%$) at 50/60 Hz.

   

• Advertised Maximum Current: 500A (Note: While named “500S,” its real-world continuous welding current on a standard single-phase 220V plug typically peaks around 140A to 180A).

   

• Output Range: 20A – 140A (Usable range).

   

• Electrode Compatibility: 1.6 mm to 3.2 mm (Can push up to 4.0 mm for light tasks, though 2.5 mm and 3.2 mm rods are the sweet spot).

   

• Duty Cycle: Rated around $60\%$, meaning it can run continuously for about 6 minutes out of a 10-minute cycle at its optimal output before needing to cool down.
