A system and method of welding is provided where welding power supply has a first output electrically coupled to a welding electrode and a second output electrically coupled to a switching mechanism. The welding power supply provides a welding current through either of the first and second outputs to weld at least one work piece. The switching mechanism has at least a first and second switch position, where the first switch position is coupled to a first position on the at least one work piece and the second switch position is coupled to a second position on the at least one work piece, which is remote from the first position. During welding the switching mechanism switches between the first and second switch positions to change a current path for the welding current during through the at least one work piece.
