ABSTRACT:
A system and method for powering a welding-type device from a plurality of distinct outlet configurations is disclosed. The power cord system includes a power cord having a plurality of conductors extending therethrough. An end of the power cord is constructed to engage an individual adapter of a plurality of adapters. Each of the plurality of adapters has a prong configuration that is different than a prong configuration of the other adapters such that each of the plurality of adapters is constructed to electrically connect the power cord to a uniquely configured outlet. A welding-type device according to the present invention is quickly and efficiently adaptable to operate at a plurality of different input power signals.
