Saturable reactor type welding transformer is popular used in welding. The welding transformer reduces the voltage from the source voltage to a lower voltage (usually between 15 and 45 volts) that is suitable for welding. In this welding transformer an isolated low voltage, low amperage dc circuit is employed to change the effective magnetic characteristics of the magnetic core. Coilcore focus on ...
