The CEA MF-300 Medium Frequency Inverter Spot Welder is a three-phase resistance spot and projection welding machine designed for industrial mass production. It operates at 400V with a power rating of 300 KVA and features the WS 402 control system, making it suitable for manufacturers requiring precise and high-quality welds.

This medium-frequency inverter welder offers constant current control and rapid millisecond current regulation, ensuring superior control of the energy delivered to the weld nugget compared to traditional 50 Hz equipment. These features enable consistent weld quality, especially important in demanding industrial applications.

The MF-300 excels in welding thin materials and metals that are traditionally difficult to weld, such as copper, brass, aluminium alloys, zinc-plated, and other coated steels. Its ability to monitor the welding process every 1 millisecond (1000 Hz) allows for precise energy management and improved weld integrity.

Key benefits include:

• Advanced medium-frequency inverter technology for enhanced weld quality
• Suitable for resistance spot and nut projection welding
• Ideal for thin gauge materials and hard-to-weld metals
• High-speed process monitoring for consistent production
• Designed to meet the requirements of high-volume industrial manufacturing
