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.
The main features of this controller:
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. 6: the design of reliable zero crossing detection circuit to ensure that the SCR phase shift accuracy. 7: the controller is compatible with 40A scr. 8: digital control interface, you can display the current time and current settings. 9: time input 1-50, unit cycle (1 cycles is 20ms)
