Main Applications and Features:
The SP-15 series is widely used for heating small metal parts such as:
  • Brazing of machining tools
  • Brazing of diamond tools
  • Heat treatment of small components
  • Melting of small amounts of gold, silver, copper, and brass
  • Melting of small amounts of steel and stainless steel

The SP-15 series machines are known for their simple structure, high reliability, and cost-effectiveness. They have become one of the most popular models in the market and are widely used across various industries for metal heating applications.

Working Principle and Structure
In the SP-15 series, a series oscillating circuit is used. The high-frequency transformer outputs low voltage and high current power through the induction coil. The SP-15 series was the first model developed by our company. It uses MOSFET components and our first-generation inverting control technology, making it easy to operate and maintain. These features contribute to its widespread use both domestically and internationally.

Advantages of Timer Function in SP-15A:
  1. Heating power, retention power, heating time, retention time, and cooling time can be set and adjusted, allowing precise control over the heating process.
  2. Ideal for repeated or high-speed heating of small parts.
  3. When used for brazing, proper timing parameters allow rapid heating and retention, ensuring even temperature distribution and smooth melting of the brazing material for strong joints.
Advantages of the Split Transformer in SP-15B:
  1. The high-frequency transformer is separated from the generator, connected via a 2-meter cable, enhancing flexibility and safety.
  2. Suitable for dirty or corrosive environments, with the generator placed in a clean area to improve reliability.
  3. The compact and lightweight design of the transformer makes it easy to integrate into production lines or mobile setups.
