The Edon welding machine (MMA-300S) is one of Edon’s very popular models, generally categorized as a portable, single-phase MMA (Manual Metal Arc or “Stick”) inverter welder intended for household, light commercial, and DIY use. The “300” in the model name is often a marketing label for the machine’s series, while the actual continuously rated output is typically lower. However, some variants claim a higher output. Key Specifications (Most Common Single-Phase Model) Feature Typical Specification Note Welding Process MMA (Stick Welding) Uses coated stick electrodes (E6013, E7018, etc.). Technology Inverter (Often IGBT or sometimes MOSFET) Provides efficiency and stable DC output. Input Voltage Single Phase,220V(±10%)/50-60 Hz Designed for standard wall power. Max Output Current (Rated) 180A to 200A This is the realistic continuous output for a 220V unit. (Some listings claim 300A max, which is a theoretical peak). Current Range 20 A−180 A (or 20 A−200 A) Wide range for welding thin to medium materials. Rated Duty Cycle 60% @ Rated Current (e.g., 180A) Can weld for 6 minutes out of every 10-minute period at the stated rated current. Input Power Capacity ∼7.8 KVA to 9 KVA Maximum power consumption. No-Load Voltage (V) ∼59V to 75V Assists in easier arc striking. Usable Electrode Size 1.6 mm to 4.0 mm (Some listings claim up to 5.0 mm) Supports common electrodes for home and light industrial use. Weight Approximately 6.7 kg to 8.5 kg Portable design with a carry handle. welding machine
