Specifications (Typical) Specification Details Model ARC-500S Welding Type MMA (Stick) Input Voltage 220V $\pm 10\%$ (Single Phase) Frequency 50/60 Hz Maximum Output Current Up to 500A (Note: While marketed as 500A, the actual continuous welding current for most models operating on 220V is typically around 140A – 180A). Electrode Diameter Compatible with electrodes ranging from 1.6 mm to 5.0 mm. Duty Cycle Typically $60\%$ at $40^\circ\text{C}$. This means it can weld continuously for 6 minutes out of every 10-minute period at the rated current.
