The Edon LV-400 (or sometimes referenced as TB-400 or ARC-400S) is an inverter-based MMA (Stick) welding machine, suggesting a heavy-duty or industrial-class unit based on the “400” rating. However, Edon, like many manufacturers in this class, uses a nominal current rating (400) that is often its peak capability. The practical, continuously rated output for the common single-phase model is much lower. Here are the typical specifications and features for the most common version of the Edon “400” class machine designed for single-phase use: Key Specifications (Single-Phase “400” Class Model) Feature Typical Specification Note Welding Process MMA (Stick/Shielded Metal Arc) DC Inverter Uses coated electrodes for welding. Technology IGBT/MOSFET Inverter Technology Provides high efficiency and a stable DC arc. Input Voltage Single Phase, AC 220V±15%, 50/60Hz Common for heavier-duty single-phase power. Max Output Current (Rated) ∼160A to 200A The continuous output for a machine with a 400 nominal rating on single-phase 220V. Current Range 20A−160A (or higher peak) Allows for welding thin materials up to medium/heavy plate. Rated Duty Cycle 60% @ Rated Current (∼160A) Can weld continuously for 6 minutes out of a 10-minute period at its rated current. Input Power Capacity ∼6.8 KVA Maximum power consumption. No-Load Voltage (V) ∼60V to 65V High enough for easy arc ignition. Usable Electrode Size 1.0 mm to 4.0 mm (Up to 5.0 mm possible at lower duty cycle) Handles a wide variety of rod sizes.
