3X Digital Spot Welding Machine Control Display Spot AC 110V 220V to 9V Transformer Controller Board 100A

3X Digital Spot Welding Machine Control Display Spot AC 110V 220V to 9V Transformer Controller Board 100A Description

Feature:
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 and the current to achieve the purpose of welding.
color: red
material: plastic

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 and the foot adopts the screw free fast connection terminal, more convenient and reliable.
4: input , current using high-precision single potentiometer, to ensure reliable input, convenient
5: -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.
digital control interface, you can display the current and current settings.
input 1-50, unit cycle (1 cycles is 20ms), current input (30-99%)
model: 100A
