MFDC Spot Welding Machine

The medium frequency spot welding machine is an advanced welding equipment. It has a wide range of applications, with a small size of the welding transformer but high output energy. In the automotive industry, its integrated transformer rapid welding clamp further demonstrates its advantages. Its superior performance is due to the fact that the frequency of the welding transformer is increased from 50/60Hz to 1000Hz, which greatly reduces the weight of the core material. Additionally, the rectifier diode in the transformer’s secondary circuit converts electrical energy into a direct current power supply for welding.

Product Characteristics:

1. The welding current is DC, and when there are inductive or magnetic materials in the secondary winding, it will not affect the welding process.
2. Using a three-phase power supply enhances the system’s ability to adapt to grid fluctuations and voltage drops.
3. Compared to mains frequency power, it offers more precise and faster current control.
4. Faster attainment of the set current: medium frequency welding can adjust the welding current up to 20 times faster than traditional mains frequency.
5. The process is more reliable, as DC welding provides better results for most metals used in spot welding.
6. Reduced operational costs, including saving energy per spot weld and shortening the welding cycle.
