The Edon welding machine (ARC-630S) is presented as a heavy-duty MMA (Stick) inverter welder, though its listed specifications often conflict, typical of some models that use high numbers in the name (like 630) to denote a class rather than a verifiable maximum output on common household current. However, based on multiple product listings, here is a summary of the common specifications and features of the Edon ARC-630S: Key Specifications (Varies Significantly by Vendor) The data for the “630S” model is the most inconsistent. There appear to be two main claims: a light-duty/portable version and a heavy-duty version. Feature Light-Duty Claim (More Common on 220V) Heavy-Duty/High-Amp Claim (Less Common) Welding Process MMA (Stick) DC Inverter MMA (Stick) DC Inverter Technology IGBT Inverter Technology Advanced IGBT Inverter Technology Input Voltage Single Phase,220V Dual Voltage: 220V / 380V (Required for high amps) Current Range 20 A−140 A (Or 20 A−180 A) 45 A−630 A (Requires high power input) Rated Output (A) ∼140A to 180A ∼360A (Rated at 60%) or even 600A Duty Cycle 60% @ Rated Current (∼140A to 180A) 60% @ 600A (Highly unlikely on standard 220V) Usable Electrode Size 1.6 mm to 4.0 mm Up to 5.0 mm (Implied by high current) Weight ∼6 kg ∼6 kg to 9 kg
