An article to read the advantages of intermediate frequency inverter spot welding machine

IF inverter spot welding machine? I believe many friends are interested in it. Today, we will introduce it to you.

medium frequency inverter spot welding machine is a new variety developed in the mid-1980s after the inverter arc welding machine. The basic principle is: the three-phase alternating current input from the power grid requires small power grid capacity, stable direct current after welding the same materials and junction rectification and filtering, and the required power grid capacity is only 1/10 of that of the AC spot welding machine.

Compared with the power frequency welding machine, intermediate frequency inverter spot welding machine has the following characteristics:

1, with the continuous improvement of switching elements and control technology, this kind of welding machine control is more reliable. When a fault is found, such as a short circuit, the 1GBT switch can be cut off within 3us, which is much faster than the thyristor.

2. Since the secondary circuit is high-quality DC, there is no inductive resistance loss, and the energy saving effect is remarkable. The excellent performance of intermediate frequency inverter spot welding machine increases the variety of weldable materials and can be used for welding of complex materials such as galvanized steel plate and aluminum alloy with poor weldability.

3. In the automobile industry, when using robot spot welding operation, the advantages of intermediate frequency inverter spot welding machine are particularly significant, which can reduce the burden of robots, operate flexibly, have a more compact structure, and facilitate the use of transformer-connected welding tongs. In addition, the inverter power supply can also be used in seam welding of cans.

4. The manufacturing cost of medium frequency inverter spot welding machine has been significantly reduced in recent years. If the enterprise has the condition, it is recommended to choose the medium frequency inverter spot welding machine.
