NY-D01 100A/40A Spot Welding Machine Control Board Welder AC 9V Transformer Controller Panel Adjust Time Current Digital

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 time and the current to achieve the purpose of welding 1 the use of STM8 industrial microcontroller control center 2 strong and weak electricity through optocoupler isolation safe operation 3 the power line and the foot switch line adopts the screw free fast connection terminal more convenient and reliable 4 input time current using high precision single potentiometer to ensure reliable input convenient5 on 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 7 the controller is compatible with 100A scr 8 digital control interface you can display the current time and current settings 9 time input 1 50 unit cycle 1 cycles is 20ms current input 30 99 AramDescription of the fault Time or current is not adjustable the number does not changeSolution First look at the pad on each of the 3 pins of the potentiometer As shown beloweWhen there is a break you can re weld it with a wire Note The position of each potentiometer is as shown below Powerful functions ① Compatible with 41 100A thyristor② Strong and weak electrical use optocoupler isolation the operation more secure ③ Create free quick connec
