This invention deals with a spot electrical welding machine which is technically applied to the electronics industry and micro-electronic industry. A spot electrical welder optimally directly welds enameled wires, fine wires or relevant thin sheets of metal, and metal tapes with Phi 0.02 mm-Phi 0.80 mm. This spot electrical welder comprises of an electrode, a main processor which functions as a power supply control, and a weld head which is composed of an electrode clamp and an adjusting device of electrode force. Due to the special structure of the electrode's tip which has a certain resistance Ohm contact, the main processor circuits provide for a proper work current while wedding enameled wires and further eliminates the need for insulation by hand. In addition, the spot electrical welder makes weld points even and steady, allows for simple and convenient operation and lowers welding time.
