Edon Inverter Welding Machine LV 250

The Edon Inverter Welding Machine LV 250 (often seen as LV-250S) is another popular model in Edon’s range of compact and portable MMA (Stick) welders. Like its LV 300s counterpart, it leverages inverter technology for efficiency and a stable welding arc.

Here’s a breakdown of what to expect from the Edon LV 250:

Edon Inverter Welding Machine LV 250 (LV-250S)

• Type: MMA (Manual Metal Arc) / Stick Inverter Welder.
  • Inverter Technology: Utilizes IGBT technology to convert input power efficiently, resulting in a lightweight, energy-efficient machine with a stable arc. This is a common feature across modern Edon welders, ensuring better weld quality and user experience compared to older transformer models.
  • Portability: Designed to be very compact and lightweight, making it easy to carry for various jobs, whether at home, in a small workshop, or on-site.

Key Specifications (Commonly Advertised):

• Input Voltage: 220V AC (single phase), 50/60 Hz. This is standard for most electrical outlets in Kenya.
• Output Current Range: While the “250” in the model name suggests 250 Amps, common specifications indicate the actual maximum output current for the LV 250s is typically around 140A to 180A. Some listings might state 250A, but it’s important to verify the continuous output rating. For general stick welding, an output in the 140A-180A range is more than sufficient for most common electrode sizes.
• Usable Electrode Diameter: Typically supports electrodes from 1.6 mm to 3.2 mm. Some heavier-duty models might claim up to 4.0mm, but 3.2mm is a very common and realistic upper limit for this class of machine.
• Input Capacity (Power Consumption): Around 5.7 KVA.
• Output Voltage: Around 25.6V (at rated current).
• No-load Voltage (OCV): Approximately 60V to 65V. This voltage helps with arc starting.
• Efficiency: Often stated around 85%, indicating good power conversion.
• Power Factor: Around 0.73.
• Duty Cycle: Commonly rated at 60%. This means it can weld continuously for 6 minutes out of every 10-minute period at its maximum rated output before needing a cool-down. This is generally adequate for DIY and light professional tasks.
• Weight: Very lightweight, often around 4.2 kg to 4.5 kg, which significantly contributes to its portability.
• Dimensions: Compact, e.g., 320 x 150 x 280 mm or similar.
• Protection Features: Like other Edon inverter welders, it usually includes built-in protections against over-voltage, under-voltage, over-current, and overheating to safeguard both the machine and the user.
• Hot Start & Anti-Stick: These are standard features in Edon inverters, making arc initiation easier and preventing electrodes from sticking to the workpiece.
• Digital Display: Many models include a digital display for precise current adjustment.

Included in the Package:

Typically, the package will contain:

• Edon LV 250 (or LV-250S) Welding Machine
• Electrode Holder with Cable
• Ground Clamp with Cable
• User Manual
• Basic welding accessories like a simple mask and wire brush (though an upgrade to an auto-darkening helmet is always recommended).
