Product Description
Medium frequency inverter spot projection welding machine is a set of advanced welding equipment. Widely used, welding transformers have a small volume and large output energy. The advantages of portable spot welding machines used in the automotive industry are even more evident. Its superior performance is due to the increase in the frequency of its welding transformer from 50/60Hz to 1000Hz, which greatly reduces the weight of the iron core material. In addition, the rectifier diode in the secondary circuit of the transformer converts electrical energy into DC power for welding. This can greatly improve the value of the secondary circuit inductance coefficient, which is an important factor leading to energy loss and can almost be ignored in DC welding circuits, thereby minimizing production costs.

♦ Distance,angle and length of welding arm can be made according to customers' requests.
Features:
1. Three-phase power input, high operating frequency, low transformer loss, and significant energy saving effect.
2. The transformer can be up to 300kva, the transformer secondary tube brand is ABB.
3. More accurate and fast current control: More and more accurate analysis of parameters compared to low-frequency systems.
4. Reduce operating costs, including saving welding energy at each point and shortening the welding cycle.
5. Faster reaching the set current: The intermediate frequency can adjust the welding current 20 times faster than traditional technology.
6. Greater adaptability to grid fluctuations and voltage drops: A portion of energy is stored by the inverter and then fed to the load, replacing the method of directly supplying power to the load from the grid.
Application: The portable spot welding machine is widely used in the automobile, motorcycle, aviation, sheet metal structural components, medical equipment, light industrial machinery, household appliances and other fields. And it can welding carbon steel sheet, coated steel sheet, stainless steel sheet, aluminum sheet metal.
