Supplier's note

  1. Technical Breakthroughs:

    • AVR Voltage Regulation: Ensures stable 220V output, protecting tools and electronics from voltage fluctuations.
    • Dual AC/DC Output: Enables simultaneous power generation and welding without needing additional equipment.
    • Honda GX390 Engine: Combines fuel efficiency (20% lower emissions than 2-stroke engines) with reliability for 24/7 operation.

  2. Version Selection Guidance:

    • Base Model: Ideal for occasional users (e.g., small workshops) needing basic welding and power for light tools.
    • Advanced Model: Suitable for medium-duty tasks (e.g., construction crews) requiring extended runtime and higher current.
    • Pro Model: Designed for heavy-duty professionals (e.g., industrial contractors) demanding peak power (6.0kW) and 250A welding capacity for large-scale projects.

With the Pro Model’s 250A DC output, you can handle thick metal sheets effortlessly, while its 8.5-hour runtime eliminates frequent refueling. Pair this with the AVR for uninterrupted power to sensitive equipment, ensuring productivity even in remote locations.
