A magnetic based welding tool having an adjustment knob, a pivot arm, and a copper alloy pad, designed to assist with welding holes, for example, in sheet metal, that are to be welded closed with a MIG or TIG welder, by providing a backup to the hole, to keep the welding material from coming through the hole in excess amounts, and a magnetic base to hold the tool onto a ferrous metal panel, such as steel, with an adjustable arm to keep the copper alloy pad away from the magnetic base and in firm contact with the surface to be welded.
