Abstract: A micro-welding electrode which is installed in a welding machine and applied to the electronics industry and spot electric welding industry. The micro-welding electrode includes two integrated electrodes which are made from high-temperature-resistant materials and has a placed insulation between the two electrodes. The insulation between the two parallel electrodes is an insulative chipbonder with the function of agglutination, fixation, insulation and separation, and allows for dispensing with an insulative rivet. Simultaneously, the tip of the two parallel electrodes is positioned into mutual Ohm contact. Not only can the electrode directly weld enameled wires but also has the quality of effectively welding bare wires, sheet metal and metal tapes. The electrode has a simple and reliable construction, is low in production cost, has a good quality of welding and allows for high work efficiency.

Abstract: 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 &PHgr; 0.02 mm-&PHgr; 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.
