The high efficiency TANDEM pulsed MAG welding machine is a efficient machine which used widely in the welding filed. TANDEM pulsed MAG welding machine 's heat input the adjusting range is wide and have high efficiency electric energy, It's a high quaLity and high efficient machine. Our TANDEM pulsed MAG welding machine used the 16-bit single chip dsPIC30F6011 to be the main control chip, two 8-bit...
A variable parameter PI adjustment system based on the fuzzy control technique was developed, which improved the performance of the dynamic response of inverter welding power supply effectively. DSPIC30F2020 was used as the core control chip, and a two-input two-output fuzzy controller was established. By taking the welding current deviation and its changing rate as input signals, and fuzzy processing...
