CA 2326024

An electric arc welder powered by a plurality of liquid organic fuel cells. The fuel cells use a methanol/water mixture as the organic feed. The fuel cells produce carbon dioxide as a reactive product which is used an a shielding gas during the arc welding process. The fuel cells are stacked together to produce the desired arc voltage and current between an electrode and the workpiece. The arc welder includes a welding current to control the current wave shape through the electrode and to control or increase the voltage through the electrode.
