The machines use a series oscillating circuit. High-frequency transformers convert low-voltage, high-current power into the induction coil. The main oscillation structure is as follows:
Inside the SPG series, IGBT modules and third-generation inverter control technology are used. This includes soft and dual control inverter technology, allowing separate adjustment of power and frequency. The inverter circuit uses IGBT and frequency tracking to achieve fast and accurate soft switching control. These innovations improve machine quality, reliability, and allow 100% duty cycle operation.
Additionally, the oscillating capacitor is connected to the secondary coil of the transformer, which keeps the primary voltage low, reducing issues like sparks and insulation problems, enhancing overall reliability and performance. The transformer is compact, lightweight, and energy-efficient.

- Heating and retaining power, time, and duration can be pre-set and adjusted, enabling precise control over the heating process.
- Perfect for repeated or high-speed heating of small parts.
- Useful in brazing operations where precise timing ensures proper melting and spreading of the filler material.
- The high-frequency transformer is separated from the generator, with a minimum of 2 meters of connecting cable.
- Ideal for dirty or corrosive environments, keeping the generator in a clean area for better reliability.
- Compact and lightweight, making it easy to integrate into production lines or mobile setups.
