100A Spot Welding Machine Control Board Adjustable Time Current Digital Display Welder Transformer Controller Board,model: 100A

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. 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 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 40A scr. 8. Digital control interface, you can display the current time and current settings. 9. Input time of 1-50,
