Main Applications and Features:
The SP-15 series is ideal 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 quantities of steel and stainless steel
The SP-15 series machines are known for their simple structure, high reliability, and cost-effectiveness. They are widely used in various industries around the world for metal heating applications.

Working Principle and Design
In the SP-15 series, a series oscillating circuit is used, which converts high-frequency power through a transformer into low-voltage, high-current output that passes through an induction coil. The SP-15 series was the first model developed by our company, using MOSFET components and our first-generation inverter control technology. These features make the machines easy to operate, maintain, and highly reliable, which is why they are popular both domestically and internationally.

Advantages of Timer Function in SP-15A:
  1. Heating power, holding power, heating time, holding 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 settings allow for rapid heating and holding, ensuring the brazing material melts smoothly and forms a strong joint.
Advantages of Split-Type Design in SP-15B:
  1. The high-frequency transformer is separated from the generator, with at least a 2-meter connecting cable.
  2. Suitable for dirty or corrosive environments, allowing the generator to be placed in a clean area, improving system reliability.
  3. The compact and lightweight transformer makes it easy to integrate into production lines or move within machinery.
