100a Spot Welding Machine Control Board Adjustable Time Current Digital Display Welder Transcompatiblemer Controller Board 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 input5. 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, cycle unit (1 cycles is 20 ms), current input (30-99%).Specifications:Material: PCBColor: RedCurrent: 40A / 100A (optional)100A Thyristor / 40A Thyristor: Just ThyristorPower transformer: Just 1 AC 9V transformerWelding Pin: 3 * 100 Welding Pin Alumina CopperFoot Switch: EKW-5A-B Aluminum Foot SwitchDKJ10-25 Connector: European Quick Fitting Cable Quick DKJ10-25 ConnectorRed Rocker Switch: Red Rocker Switch Fused Power SocketItem Size: Control panel: 80*60mm / 3.1*2.4" Display panel: 40*35mm / 1.6*1.4"Item Weight: 86g / 3.0ozPackage Weight: 87g / 3.1ozPackage Size: 80*60*30mm / 3.1*2.4*1.2"Note:This version for mass production without flying version.The package contains the control panel, display panel, cable matching, red green button.Because of the ease of consumption of silicon controlled parts, easy to discriminate in the commissioning process, it is recommended that friends together spare parts, easy to replace. please choose your own.Package List:1 * Main Board1 * Display Board1 * Cable Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
