Necessary for all forms of welding, power sources are required to supply the electrical current needed to power the welding equipment. Different forms of welding require different power supplies, such as each requires a different level of electrical current in order to work correctly.

Power source types

The most common welding power sources fit into a few different types, such as transformers and generators.

Transformers swap the power from the mains, changing it to a high current and low voltage from a low current and high voltage. The output current and voltage can be selected by the welder, based on the welding work they are carrying out. Rectifiers are sometimes used alongside transformers to convert the AC into DC.

Generators, such as diesel welders, are used as a way of producing electricity for welding. Some generators are actually powered by electricity, but the electricity they produce can be of a different voltage and current without the need for a transformer.

Other types of power sources exist, such as inverters which can be used for other kinds of welding.
