    The best

    Posted by Ebenezer on Feb 02, 2024

    The Kaierda Inverter Manual Arc Welding Machine (ZX7-630S) provides a decent welding experience. The inverter technology does contribute to a smoother welding process, and the machine's power output is satisfactory for most welding tasks. The user manual, while not overly detailed, provides enough information for basic setup and operation. However, the build quality seems average, and the overall design lacks some user-friendly features that could enhance the welding experience. It's a middle-of-the-road option, suitable for those with moderate welding needs who are looking for a budget-friendly machine.

    Works great

    Posted by Oliver Innocent on Feb 02, 2024

    I had high expectations for the Kaierda Inverter Manual Arc Welding Machine (ZX7-630S), but unfortunately, it fell short in some aspects. The user manual is not as detailed as I would have liked, making it challenging for a beginner like me to set up and operate the machine effectively. Additionally, the build quality of the machine is not as robust as I expected, and the durability is questionable. While the welding results are acceptable, I encountered issues with stability during prolonged use. I believe there are better options available in the market at a similar price point with more user-friendly features.
