continuous heat supply generated by flat output current of the intermediate frequency welding machine makes the temperature of the nugget rise continuously. At the same time, the precise control of the current rising slope and time will not cause spatter due to heat jumps and uncontrollable current rising time.
IF inverter spot welder has a flat output welding current, which ensures the high-efficiency and continuous supply of welding heat. And the power-on time is short, reaching the ms level, which makes the welding heat-affected zone small, and the solder joints are formed beautifully.
high working frequency (usually 1-4KHz) of the intermediate frequency spot welding machine, the feedback control accuracy is 20-80 times that of the general AC spot welding machine and the secondary rectification spot welding machine, and the corresponding output control accuracy is also very high.
energy saving. Due to high thermal efficiency, small welding transformer and small iron loss, the inverter welding machine can save more than 30% energy than AC spot welding machine and secondary rectification spot welding machine when welding the same workpiece.
It is used for spot welding and nut projection welding of high-strength steel and hot formed steel in automobile manufacturing industry, spot welding and multi-point projection welding of ordinary low-carbon steel plate, stainless steel plate, galvanized plate, aluminum plate and wire, resistance brazing and spot welding of copper wire in high and low voltage electrical industry, silver spot welding, copper plate brazing, composite silver spot welding, etc.
A: The frequency of maintenance should be determined according to the use of the spot welder and the production environment, and it is usually recommended to perform maintenance once a month.
A: The power supply selection of the spot welding machine should be determined according to the power of the equipment and the use environment to ensure that the equipment can operate normally.
A: Spot welders require the use of protective glasses, gloves, and other safety gear to keep operators safe.
A: The power supply should be connected according to the electrical requirements and safety standards of the equipment.
A: The service life of the spot welding machine depends on factors such as equipment quality, maintenance and use environment, usually between 5-10 years.
A: Welding speed depends on the size and complexity of the welding project and is usually several times per second.
