Abstract
The invention concerns a welding machine for electrically resistance welding together, to form a mesh, at their points of intersection in a mesh production plane, two crossed groups of parallel wires. The machine incorporates at least two pairs of opposed cooperating welding electrodes, one of said pairs being arranged on each side of the mesh production plane. A pair of transformers have their primary windings connected in series and each pair of said electrodes are connected to the secondary winding of one of the transformers in such a way that in operation the welding current will flow through the electrodes and through the secondary windings of the transformers in series.
