[DETAIL]<br>Transformer Controller Board Adjustable Time Current Welder Transformer Controller Board Digital Display DIY Battery Accessories<br>Feature:<br>1. Controller:<br>STM8 industrial control center microcontroller is adopted. Isolate strong and weak current through optocoupler to ensure safe operation.<br>2. Design:<br>The power line and foot switch line use bolts as quick connection terminals, which is more convenient and reliable.<br>3  Input time:<br>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.<br>4. Function:<br>reliable zero-crossing detection circuit design ensures SCR phase<br>transfer<br>accuracy. The controller is compatible with 40A scr. The digital control interface can change the current time and current settings.<br>5.<br>Setting<br>:<br>input time is 1-50, cycle unit (1 cycle is 20 ms), current input (30-99%).<br>Specification:<br>Material: PCB<br>Color: red<br>Current: 40A/100A (optional)<br>100A thyristor/40A thyristor: ordinary thyristor<br>Transformer: common 1 AC 9V transformer<br>Welding pin: 3 * 100 welding pin aluminum oxide copper<br>Foot switch: EKW-5A-B aluminum foot switc<br>DKJ10-25 connector: European type quick connector cable DKJ10-25 quick connector<br>Red rocker switch: the red rocker switch is fused with the power socket<br>Size:<br>Control panel: 8x6cm/3.15x2.36in<br>Display screen: 4x3.5cm/1.57x1.38in<br>Origin: Mainland China<br>Model Number: Spot Welder Module<br>Note:<br>Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
