Output current and voltage is delivered by power sources with the electrical characteristics that make arc welding possible. For shield metal arc welding, (SMAW), two types of power sources are utilized: static machines that convert energy supplied by electric power companies and motor generators that combust fuel (chemical energy). The selection of a power source is the most crucial and most expensive element of the welding electrical circuit and is the first consideration in implementing the SMAW process.
