Welding Transformer

Welding Transformer

The transformer, housed in a welding machine, is used to convert the high-voltage input or, primary power, from the wall plug and this is usually from 208 to 600 volts, with a low alternating current (AC) from 15 to 55 amps. This is transformed in the secondary power side to a lower voltage of up to 80 volts and a range of welding currents up to 1000 amps AC or more, depending on the process and equipment.
