The welding transformer is a double winding transformer. In order to adjust the arc ignition voltage, the original winding is equipped with a branching head, and a tap switch is used to adjust the no-load voltage of the secondary side. The primary and secondary windings are separately installed on the two iron core legs, so that the transformer itself has a larger leakage reactance, so the terminal voltage of the secondary side will drastically drop with the increase of current. An iron core reactor is connected in series in the auxiliary winding circuit for adjusting the welding current. Changing the length of the air gap of the reactor, the current will increase as the air gap grows.
The main forms of welding transformers are moving iron type, moving coil type and tapped type. The basic principle of welding transformer has not changed much in decades. The welding transformer produced and used at home and abroad is a special step-down transformer with steep external characteristics. Although it can be divided into several methods according to its method of obtaining steep external characteristics, the combination of reactor and transformer, and the method of adjusting current, the basic principle is the basic principle of general transformer.
