The Edon TB-400 (sometimes branded as the Tornado XP TB-400) is a popular model of a compact, single-phase MMA (Manual Metal Arc or “Stick”) inverter welding machine. The “400” in the model name often implies a high theoretical capacity, but the practical, sustained output is lower, which is common with portable inverter welders. Key Specifications Feature Typical Specification Note Welding Process MMA (Stick Welding) Primary function. Technology Inverter (IGBT Technology) Makes the machine lightweight and efficient. Input Voltage Single Phase,220V/50−60Hz Standard household power supply in many regions. Max Output Current 160 Amperes (A) This is the typical rated maximum output current, despite the “400” in the model name. Current Range 20 A−160 A Provides flexibility for thin and medium-gauge metals. Rated Duty Cycle 60% @ 160A Can weld continuously for 6 minutes out of every 10 minutes at its max rated output. Usable Electrode Size 1.6 mm to 4.0 mm Supports common electrode sizes for general-purpose welding. No-Load Voltage 65V to 67V Ensures easy arc ignition. Weight Approximately 3.4 kg to 4.6 kg Very lightweight and highly portable. Protection Class IP21S Basic protection against dripping water and solid objects. Export to Sheets
