What is the inductance of the main transformer of electric welding machine?

This situation depends on the specific model and manufacturer.

The main transformer inductance of different welding machines will be different. In general, the inductance of the main transformer of electric welding machine is generally between 65438+1000 MH-1000 MH. Among them, the main transformer inductance of high-power welding machine will be larger, while the main transformer inductance of some low-power welding machines may be smaller.

The inductance of the main transformer of electric welding machine refers to the ratio of induced electromotive force to the current generated during operation, which has great influence on the performance and stability of electric welding machine. If the inductance is too small, it will lead to unstable current output and excessive heating. On the other hand, if the inductance is too large, it will increase the size and weight of the welding machine and the price will increase accordingly.
