Arc-welding-machine

General welding works and transformer similar to a step-down transformer. Both ends of the teeth and the coil is welded workpiece and electrode, the arc ignition, high temperature will be in the arc gap and electrode welding jobs.

Welding transformer has its own characteristics, that is, the characteristics of a sharp decline in voltage. After ignition in the electrode voltage drop; in the adhesion of electrode is shorted, the voltage is also dropped sharply. The causes of this phenomenon is the welding characteristics of the transformer core produced.

Welding of the operating voltage of the regulator, in addition to one of the 220/380 voltage transformation, has tapped secondary coil voltage transformation, as well as to regulate the use of core, core to enter the number of adjustable, magnetic circuit to shunt into the more Welding voltage is lower.
