The Edon welding machine (MMA-250S) is a popular model in Edon’s lineup of portable Stick (MMA) inverter welders, designed primarily for use on standard single-phase power. The “250” in the model name indicates the nominal or maximum output of the machine, but the continuously rated output is typically lower, as is common with many portable inverters of this class. Key Specifications (Most Commonly Listed Single-Phase Model) Feature Typical Specification Note Welding Process MMA (Stick/Shielded Metal Arc) DC Inverter Uses coated electrodes for welding. Technology IGBT or MOSFET Inverter Technology Provides high efficiency, stable arc, and a compact size. Input Voltage Single Phase,AC 220V(±10%)/50-60 Hz Designed for standard electrical outlets. Max Output Current (Rated) 160A to 200A The verifiable continuous output for a 220V unit. (Some listings show 250A max current range, which is the machine’s peak capability). Current Range 20 A−160 A (or 20 A−250 A) Wide range for thin sheet metal to medium plate welding. Rated Duty Cycle 60% @ Rated Current (∼160A to 200A) Can weld continuously for 6 minutes out of a 10-minute period at the specified current. Input Power Capacity ∼6.8 KVA to 9 KVA Maximum power consumption. No-Load Voltage (V) ∼59V to 75V Ensures easier arc ignition. Usable Electrode Size 1.6 mm to 4.0 mm Handles common electrode diameters used in DIY and light fabrication. Weight Approximately 7.5 kg to 8.5 kg Portable and easily transportable for on-site work.
