Capacitor discharge spot welding machine consists of mechanical and electrical components, circuit control is the core component of resistance welding technology. Monolithic computer control technology is widely used in the field of welding and has become the mainstream of resistance welding control system development. Capacitor discharge spot welder with professional industrial control single-chip microcomputer as the control core, take a variety of software and hardware anti-interference measures capacitor discharge spot welder control system.
PLC control core, effective control of the punching and discharging process, can adjust the pre-pressure, discharge, forging, maintenance, rest time and charging voltage values respectively, the specification is very convenient to adjust.
The specially designed special control circuit has the functions of phase shift trigger charging, discharge current detection and commutation discharge, which makes the capacitor discharge welder avoid the energy consumption caused by the heating of current limiting resistance and the magnetization of resistance welding transformer.
Capacitor discharge spot welder is widely used in welding of low carbon steel, stainless steel, copper and alloy. Compared with other welding methods such as AC machine, the grid instantaneous power low phase load balance, high power factor, can provide concentrated energy for the welding area, can get good surface quality, small deformation of the welded parts, can weld some non-ferrous metals with good thermal conductivity. Suitable for welding aluminum, copper and silver, nickel metal and alloy materials. This welding method has been widely used in industrial production, such as hardware, household appliances, electronics, metal utensils and other industries.
