The Edon Inverter Welding Machine LV-250S is a portable, DC inverter MMA (Manual Metal Arc) welding machine designed for both household and light industrial use [1] [2] [3]. It utilizes IGBT (Insulated Gate Bipolar Transistor) technology for efficient and stable welding performance [1] [2].

According to www.iAsk.Ai - Ask AI:

This model is characterized by its compact size and relatively light weight, making it easy to transport and operate in various settings, including outdoors [1] [2] [4]. It features an easy arc ignition with a "hot start" function, which aids in starting the welding process smoothly [1]. The LV-250S operates on a rated input voltage of 220V [1] [3]. While some sources indicate a rated output current of 140A [1], others suggest an output current range of 20-250A [2] or 20-120A [3], with a rated output voltage around 25.6V to 30V [1] [2]. The no-load voltage is typically around 60V [2] [3].

The machine's duty cycle is a key specification, indicating how long it can weld continuously within a 10-minute period at a given current before needing to cool down. For the LV-250S, the rated duty cycle is often listed as 40% at 40°C [1] [3] or 60% [1] [2]. Its maximum load power capacity is approximately 5.7 KVA [1]. Safety features include over-voltage, under-voltage, over-current, and overload protection [4]. The Edon LV-250S is manufactured in Zhejiang, China, and typically comes with a 1-year warranty [1] [3]. It is widely available through various online and physical retailers [1] [2] [3] [4] [5] [6].
