Welding for aluminum of DTB-240 DC spot welder with CE/CCC/ISO certificate
Product Overview: The Intermediate Frequency Inverter DC Spot (Convex) Welder converts power frequency (50Hz) AC to intermediate frequency (1000Hz) DC output. Energy saving, power saving, high efficiency, low operating cost, and high welding quality. Its temporal resolution is higher than the power frequency resolution, and the control accuracy is also improved. The output current is not affected by changes in the secondary output circuit. High thermal efficiency, high output power ratio, and good welding quality. Compared with traditional power frequency welding machines, inverter type intermediate frequency DC welding machines have the characteristics of high efficiency and energy conservation. This is a technological revolution breakthrough in the field of Electric resistance welding.

Application: Especially suitable for welding of metal materials such as aluminum, copper, galvanized sheet, carbon steel, nickel, tungsten, high-temperature enameled wires, soft connections, and inductance coils. It is widely used in the welding of metal products such as automobile and auto parts manufacturing, new energy power battery, photoelectric communication, Electric light, compressor, hardware, furniture, kitchenware, etc.
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. 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.
4. More adaptable to the fluctuation of power grid and voltage drop: a part of the energy has been stored by inverter and been supplied to load. It replaces the way of power supply to load directly from the power grid.
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.
