The Edon TB-400 is a model of a compact, portable Inverter ARC (MMA) welding machine often marketed for light to medium-duty welding and hobbyist use. It’s common for these types of budget-friendly welders to have their model number (like “400”) represent a high theoretical or peak current, but the actual usable continuous output is much lower. Key Specifications (Based on Vendor Listings) The most consistent specifications across various retailers suggest the Edon TB-400 is a portable welder with an output well below the nominal 400A mark: Feature Detail Welding Process MMA (Manual Metal Arc/Stick Welding) Technology IGBT Inverter Input Voltage Single Phase 220V±15% Max Output Current Consistently listed as 160A (Amps) max in the technical specs, despite the “400” model name. Some listings show 100A. Electrode Diameter Supports 1.6mm to 4.0mm electrodes. Rated Duty Cycle 60% at its maximum rated output (e.g., 160A) No-load Voltage (OCV) Around 65V
