NY-D01 100A Digital Display Spot Welding Controller Board

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 5 On-board power supply, state, foot, trigger indicator, work status 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 100A scr. 8 Digital control interface, you can display the current time and current settings. 9 Input time of 1-50, cycle unit (1 cycles is 20 ms), current input (30-99%). Material: Plastic Metal The controller is compatible with 100A scr. Digital control interface, you can display the current time and current settings. Time input 1-50, unit cycle (1 cycles is 20ms) DOWNLOAD MANUAL NY-D01-210623 DIY Spot Welder From Microwave – Now With OLED Display! _ 8 Steps (with Pictures) – Instructables
