Working theory and structure:
These machines use a series oscillating circuit, where low-voltage, high-current power is delivered through a high-frequency transformer to an induction coil. Inside, IGBT modules and third-generation inverter control technology are used, enabling separate control of power and frequency. This ensures stable operation and efficient soft-switching control, improving machine quality and reliability while allowing 100% duty cycle operation.

Advantages and applications of models with Timer function:
- Heating and retaining power/time can be preset, offering precise control over the heating process.
- Perfect for small parts or high-speed repeated heating.
- Enables rapid heating and controlled retention during brazing, ensuring proper material flow and strong joints.
- Transformer is separated from the generator with a minimum 2m connecting cable, making it easier to place in different environments.
- Ideal for dirty or corrosive areas, keeping the generator in a clean space for better performance.
- Compact and lightweight transformer allows easy integration into production lines or mobile systems.
