Medium Frequency Inverter Pneumatic Aluminium Spot Welding Machine

DESCRIPTION

Medium frequency inverter DC resistance control system: Refer to the following picture, the three-phase AC current has been rectified into DC. Then convert into medium frequency 1000Hz square wave and connected into primary of welding transformer through inverter circuit which is composed of IGBT. After the rectification through welding transformer, the current become DC with small pulsation and being supplied to electrode for welding. The inverter will adjust the duty cycle rate of IGBT according to the feedback of primary and secondary welding current so as to achieve constant current during welding process.

APPLICATION
Sensor, LED and its lead, copper foil and vanished wire, relay, watch, capacitive slug and lead, copper wire, resistance pin, inductance, battery and stabilizer link, socket, silver contact and copper sheet, welding lightning with tungsten and molybdenum material, etc.
