[0002] Arc welding machine, also known as arc welding transformer, is a special transformer that converts the AC power of the network voltage into low-voltage AC power suitable for arc welding. It consists of a main transformer and the required adjustment parts and indicating devices. It has the advantages of simple structure, easy manufacture and repair, low cost and high efficiency. However, its current waveform is a sine wave, and the output is an AC falling external characteristic.
