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.
