The Vertical Medium Frequency Inverter DC Spot Welding Machine is designed for high-efficiency and high-quality resistance spot welding of various metal components.

By converting 50Hz AC power into 1000Hz medium-frequency DC output, the machine provides faster response, more precise current control and stable welding performance. Compared with traditional power-frequency spot welding machines, it offers higher energy efficiency, shorter welding time and more consistent welding quality.

It is an ideal solution for manufacturers looking for stable, efficient and cost-effective resistance welding equipment.

The medium-frequency inverter technology provides precise control of welding current and time, helping achieve stable welding results even during continuous production.

• Energy Saving – Higher electrical and thermal efficiency helps reduce operating costs.
• Fast Welding Speed – High output power enables short welding cycles and high production efficiency.
• Stable Welding Current – DC output provides consistent welding performance.
• High Control Accuracy – 1000Hz inverter technology allows precise control of welding parameters.
• High Welding Quality – Produces strong and consistent welding points with reduced oxidation and deformation.
• Reliable for Continuous Production – Designed for demanding industrial welding applications.

Compared with conventional power-frequency AC spot welding machines, the inverter DC welding system provides a more stable welding current and faster response.

50Hz AC Input → Medium-Frequency Inverter → 1000Hz DC Output → Precise Welding Current

This technology improves welding control and reduces unnecessary energy consumption, making it suitable for modern automated production lines.

The controlled DC welding current helps produce uniform and firm welding spots with low oxidation and reduced deformation.

For suitable applications and properly selected welding parameters, the welding surface can remain clean with minimal visible marks, reducing the need for additional finishing processes.

Stable Current + Precise Welding Time + Proper Electrode Pressure = Consistent Welding Quality
