Working Principle and Structure:
These machines use a series oscillating circuit to generate low-voltage, high-current power through a high-frequency transformer, which is then delivered to the induction coil. The main oscillation structure is designed to optimize efficiency and performance.
Inside the unit, IGBT modules and our third-generation inverter control technology are used, offering soft and dual control inverting functions. This allows independent adjustment of power and frequency, ensuring stable and efficient operation.
Additionally, the design minimizes high voltage on the primary side of the transformer, reducing risks of sparks and insulation issues. This enhances the machine's reliability and energy efficiency.

Comparison Between SPG50K and SP Series Machines:
- Both SPG50K and SP series operate within the same frequency range, but SPG50K offers superior performance.
- Higher current capacity: SPG50K machines deliver significantly higher current than SP machines of similar power. For example, SPG50K-25B has 1350A, while SP-25BD only has 900A. This makes SPG50K better suited for heating materials like copper and aluminum.
- High-frequency performance: SP machines reduce power when frequency exceeds 60kHz to protect IGBTs. SPG50K can operate at full power up to 80kHz.
- Low-frequency stability: SP machines may suffer from magnetic core saturation at low frequencies. SPG50K avoids this issue.
- Energy efficiency: SP machines have larger transformers, leading to greater energy loss compared to SPG50K.
- Reliability: SP machines often experience high voltage on the primary side, increasing the risk of sparking. SPG50K uses soft switching technology to enhance reliability.
- Versatility: SPG50K machines come with four matching taps, making them easy to adapt to different materials and applications.
Advantages and Applications of Timer Function Models:
- Heating power, retention power, heating time, and retention time can be preset and adjusted, allowing precise control over the heating process.
- Ideal for repeated or high-speed heating of small parts.
- Perfect for brazing applications, where accurate timing ensures proper melting and spreading of the filler material for strong joints.
Advantages and Applications of Split Transformer Models:
- The high-frequency transformer is separated from the generator, with a minimum 2-meter connecting cable for flexibility and safety.
- Suitable for dirty or corrosive environments, allowing the generator to be placed in a clean area for improved reliability.
- The compact and lightweight design of the transformer makes it easy to integrate into production lines or mobile setups.
