ABSTRACT:
The invention is concerned with an electrical resistance welding machine for producing a wire lattice by welding together longitudinal and transverse wires at their crossover points. The wires are fed stepwise between at least one pair of electrode devices and means synchronized with the feeding means bring the electrode devices together to clamp the wires at one of the crossover points to allow a welding operation to be effected. At least one of the electrode devices comprises a welding electrode in the form of a circularly cylindrical disc which is fitted to an electrode holder and can be rotated to bring new parts of its peripheral surface into the working position. The axis of the disc is inclined at an acute angle to the axial directions of the longitudinal and transverse lattice wires to provide an improved contact surface between the disc electrode and wires, particularly to avoid any tendency of the transverse wires to be displaced laterally by the contact pressure.
