Medium Frequency DC Welding Machine , Spot Welding Machine projection welding machine with CE/CCC/ISO certificate
Product highlights: energy saving, power saving, high efficiency, low operating cost, high welding quality.
Product overview: the Medium frequency inverter DC spot ( projection ) welding machine converts the power frequency (50 Hz) AC to the intermediate frequency (1000 Hz) DC output, the time resolution is higher than the power frequency, the control accuracy is also improved, and the output current is not affected by the secondary output circuit change, the thermal efficiency is higher, the output power is great, and the welding quality is better. Compared with the traditional power frequency welding machine, inverse medium frequency DC welding will be highly efficient and energy-saving, which is a technological revolution breakthrough in the field of resistance welding.

1. Energy Saving: Compare with using low frequency, it can help to reduce the consumption of electric energy. The transformer of the same weight could output more energy. It can also be conveniently used with the large automatic welding clamp.
2. In a semi-automatic machine, one medium frequency transformer can replace many low frequency transformers which can help to reduce the parallel connection in secondary circuit.
3. Improve the power factor, reduce the production cost.
4. Reduce interference in secondary circuit which is in the large open area: the welding current is direct current. When there is induction or magnetic material in secondary winding, the welding will not be affected.
5. More precise and fast control of current: Compare with low frequency system, it is able to analyze more parameters in a more precise way.
6. More reliable process: For most of the applied resistance welding metals, to use DC to weld will help to achieve better effect.
7. The technology of MF system is more traditional and reliable which can prevent the damage results from the breakdown of silicon controlled.
8. Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
