The principle of silicon-controlled phase shifting triggering is adopted to adjust the time and the current to achieve welding. With a digital display, you can directly see the time and current. Optocoupler isolates the strong and weak electricity, making the operation safer. Using a high-precision single potentiometer to ensure reliable and convenient input. The design of a reliable zero-crossing detection circuit ensures the SCR phase shift accuracy. Made of high-quality PCB, the control board is long-lasting. The module is 8cm long, 6cm wide, and 2cm high. It is developed for DIY or simple resistance welding.
Features:
1 The use of STM8 industrial control center microcontroller.
2 Strong and weak electricity through optocoupler insulation, safe operation.
3 The power line and foot switch line adopts the bolt the quick connect terminal, more convenient and reliable.
4 Input time, current using a high-precision simple potentiometer, to ensure reliable, convenient input
