electrolight NY-D01 DIY Spot Welder Controller Adjustable Time and Current 100A Multipurpose Controller

100A Spot Welding Machine Time Current Controller NY-D01 Spot Welding Machine Control Board Control Panel Board Module Specification: Brand new Color: as shown in picture NY-D01 Spot welding machine control board. Using SCR phase shift trigger principle, by adjusting the time, current size, to achieve the purpose of welding. STM8 industrial microcontroller to do the main control core. Strong and weak through the optocoupler isolation, the operation more secure. Input time, current using high-precision single-bit potentiometer. Zero-crossing detection circuit to ensure that the SCR phase shift accurate. Time input 1-50, unit cycle (1 cycle is 20ms), current input (30-99%). Compatible with 100A thyristor. Fine workmanship and good performance. Easy to use. Long service life.
