Edon Inverter Welding Machine LV 300s

• Type: It’s an inverter welding machine, specifically designed for MMA (Manual Metal Arc) welding, also known as Stick welding.

  • Inverter Technology: This is a key feature. Inverter welders are more advanced than traditional transformer-based welders. They use electronic components (often IGBT – Insulated Gate Bipolar Transistors) to convert input power to a high-frequency, high-voltage current, then rectify it to a stable DC output. This results in:
    • Lightweight and Portable: Much smaller and lighter than older models, making them easy to transport.
    • Energy Efficient: Consumes less power for the same output.
    • Stable Arc: Provides a smoother, more stable welding arc, which makes it easier for both beginners and experienced welders to achieve quality welds.
    • Hot Start and Anti-Stick: Common features that aid in arc initiation and prevent the electrode from sticking to the workpiece.
    • Adjustable Current: Allows precise control over the welding current.

• Model Name: LV 300s (sometimes seen as MMA-300s or Professional Welding Machine – 300s).

Key Specifications (Commonly advertised):

• Input Voltage: 220V AC (single phase), 50/60 Hz. This is standard for household and workshop power in Kenya.
• Output Current Range: While the “300s” in the model name often implies 300 Amps, many listings show the actual maximum output current for the LV 300s model to be around 160A to 180A. Some listings mention up to 300A, but it’s crucial to confirm the actual continuous output. For practical purposes, 160A-180A is sufficient for most common stick welding tasks with electrodes up to 4.0mm.
• Usable Electrode Diameter: Typically 1.6 mm to 4.0 mm. Some sources claim up to 5.0mm, but 4.0mm is a more realistic and widely supported size for this machine’s typical output range.
• Rated Output Voltage: Around 27.2 V.
• No-Load Voltage (OCV): Approximately 65V to 75V. A higher OCV can make arc starting easier.
• Duty Cycle: Often rated at 60% at 40°C. This means it can weld continuously for 6 minutes out of every 10-minute period at its maximum rated output current (e.g., 160A-180A) before needing to cool down. For most DIY or light professional work, this is more than adequate.
• Power Consumption: Around 4.3 – 7.8 kVA.
