bifrc spot welder -D01 Digital Spot Welding Machine Control Board Welder Panel Parts AC 110V/220V Transformer Controller Board(40A)

1: the use of STM8 industrial microcontroller control center. 2: strong and weak electricity through optocoupler isolation safe operation. 3: the power line and the foot switch line adopts the screw free fast connection terminal more convenient and reliable. 4: input time current using high-precision single potentiometer to ensure reliable input convenient 5: on-board power supply state foot trigger indicator working state clearly visible. the design of reliable zero crossing detection circuit to ensure that the phase shift accuracy. digital control interface you can display the current time and current settings. time input 1-50 unit cycle (1 cycles is 20ms) current input (30-99%) The control panel of the spot welding machine is a controller which is independently developed for the DIY or the simple resistance welding. The principle of silicon controlled phase shifting triggering is adopted to adjust the time and the current to achieve the purpose of welding.
