Abstract:
1. A welding-type device comprising: a power supply with a transformer configured to generate a power signal suitable for welding-type applications, the transformer comprising a single primary winding having a first end, a second end, and a center tap; a cord having a first conductor electrically coupled to the first end of the primary winding, a second conductor electrically coupled to the second end of the primary winding, a third conductor electrically coupled to the center tap of the primary winding, and a fourth conductor electrically coupled to a reference point of the power supply; a cord end having a first prong electrically coupled to the first conductor, a second prong electrically coupled to the second conductor, a third prong electrically coupled to the third conductor, and a fourth prong electrically coupled to the fourth conductor; and a plurality of adapters, each adapter having a power input side configured to receive power from a power source and a power output side configured to be coupled to the cord end, wherein the power input side of each adapter is unique to the respective adapter and the power output side of each adapter is common among the adapters whereby all of the adapters are connectable to the prongs of the cord end, the plurality of adapters comprising a first adapter and a second adapter, wherein when the first adapter is mated to the cord end, the first and second prongs of the cord end and therethrough the first and second primary winding ends are electrically coupled to the power input side of the first adapter and when the second adapter is mated to the cord end, the first and third prongs of the cord end and therethrough the first primary winding end and the center tap are electrically coupled to the power input side of the second adapter.
