Abstract: A portable welder including a housing having a handle, a power supply contained within the housing, and welding wire stored within the housing that receives welding current from the power supply. An end portion of the welding wire extends from an opening in the housing so that the end portion of the welding wire can be placed in contact with a workpiece.

Abstract: A portable welder including a housing, a power supply contained within the housing, a welding cable having a proximal end and a distal end, the proximal end of the welding cable being electrically connected to the power supply, a welding electrode that extends from the distal end of the welding cable, and a control system that adjusts welding current delivered to the welding electrode from the power supply based on user input.
