The Multi-Point (Or Multi-Spot, Multi-Head) welding machine is a welding machine that can spot weld several points at a time. It uses multiple moving spot welding electrode mechanisms on the welding machine to move back and forth on the flat workpiece and perform spot weld simultaneously. It significantly can save labor costs and increase production speed and efficiency. This welding method is widely used in the industries like Appliances (Shelves and Racks), Wire Products(Wire Mesh, Cages), Steel Grating.... etc. where multi spot welds are required in a single assembly.
