-d01 Spot Welding Machine Control Board Regulating Time And Current Digital Display Diy Control Boa

1. STM8 industrial single chip microcomputer is the main control core. 2. Strong and weak light are isolated through optocoupler, which makes operation . 3. The power line and foot switch line adopt screw free quick connect terminal, which is more convenient and . 4. High precision unit potentiometer is used for input time and current to and convenient input 5. On board power supply, status, pin, trigger indicator, and working status are clearly visible. 6. The zero crossing detection circuit is designed to the accurate phase shifting of silicon controlled rectifier. 7. The controller is compatible with 40A-100A thyristor. 8. The digital control interface can display the current set time and current. 9. Time input 1-50, unit (one is 20ms), current input (30-99%) Product name: spot welder control panel Model: -D01 Thyristor current: 100A During installation: the motherboard should be from the transformer Not on the transformer Because have strong electromagnetic interference Note: The spot welder control board is independently developed by DIY or simple resistance welding and controller. The welding purpose is achieved by adjusting the time and current based on the principle of thyristor phase-shift trigger color:Red Material:PCB+metal Package Contents: 1 x control board 1 x display panel 1 x connecting line 2 x twist caps Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
