The Welding System converts the available mains voltage into a significantly lower welding voltage. At the same time, it provides the required amperage, which also allows the power source to be adjusted and regulated. In manual metal arc welding, the amperage is the most important parameter for the quality of the connections. Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. The offered welding system is made available in various types.
