Spot Welding Machine Control Board Adjustable Time Current Spot Welder Control Board Digital Display DIY Battery Accessories

Transformer Controller Board Adjustable Time Current Welder Transformer Controller Board Digital Display DIY Battery Accessories Feature: 1. Controller:STM8 industrial control center microcontroller is adopted. Isolate strong and weak current through optocoupler to ensure safe operation. 2. Design:The power line and foot switch line use bolts as quick connection terminals, which is more convenient and reliable. 3  Input time:input time and current adopt high-precision simple potentiometer, which is reliable and convenient for on-board power supply, state, pin, trigger indicator, and working state is clearly visible. 4. Function:reliable zero-crossing detection circuit design ensures SCR phasetransferaccuracy. The controller is compatible with 40A scr. The digital control interface can change the current time and current settings. 5.Setting:input time is 1-50, cycle unit (1 cycle is 20 ms), current input (30-99%).
