Guangzhou fine source electronics co., LTD is one specialized is engaged in high precision resistance welding equipment, welding equipment, seam welding equipment development and production of high-tech enterprises. Main production and operation (spot welding machine, hot welding machine, inverter seam welding machine, inverter resistance welding equipment, inverter spot welding machine, pulse heating machine, etc.), the company is located in guangzhou overseas Chinese pioneering park, have left Dr As the core, by a group of welding of experts, professors, postdoctoral, doctoral research and development team. Strong technical strength, high precision inverter welding machine, hot pressing domestic initiation seam welding equipment, welding equipment, technology reached the international advanced level. Among them, the high precision inverter spot welding equipment used today's most advanced inverter power supply technology and microelectronic control technology, control precision, wide adaptability to the process and energy saving, high efficiency, stable, easy to operate, and many other advantages. Inverter dc spot welding power source equipment time adjust the resolution of up to 40 us) (25 KHZ inverter frequency, the response speed of feedback control, output stability is good. Dc output, concentrated heating, welding time shortened. Experiment proves that compared with 50 hz regular spot welding power supply, inverter power supply 50% energy will get the same size of solder joints. Welding procedure contains three pulse heating mode, to meet the needs of a wider range of welding, especially for stainless steel, copper, aluminum, nickel, titanium, magnesium, molybdenum, tantalum, niobium, silver, platinum, zirconium, uranium, beryllium, lead and its alloys precision connection. Applications include micromotor terminals and enameled wire, plug components, batteries, photoelectric, cables, piezoelectric crystal, sensitive components and sensors, capacitors and othe
