Arc welding machine and say arc welding transformer, is a special kind of transformer, the web voltage of alternating current into a suitable for welding of low voltage ac, by the main transformer and the adjustment of the part and instructions equipment etc.

Arc welding machine is mainly a moving iron core type, with the asanas and moving coil type 3 kinds. It is simple in structure, easy to fix, made low cost and high efficiency. But the current waveform for sine wave, output to exchange the decline characteristics, arc stability is poorer, power factor is low, but arc blow phenomenon seldom produce, no-load loss small, commonly used to hand arc welding, submerged arc welding and tungsten extremely argon arc welding method.
