12V Battery Storage Spot Welding Machine Circuit Board

A 12V battery storage spot welding machine circuit board is a crucial component of a spot welding machine used for joining metal parts together. Here’s an overview of its typical features and functionalities:

Components:

1. Microcontroller or Control Circuit:
   • Manages the overall operation of the spot welding machine, including timing, current control, and safety features.
   • Often includes a microcontroller such as an Arduino or a dedicated control circuit.
2. Power Supply Section:
   • Regulates the voltage from the 12V battery to ensure consistent power delivery during welding.
   • May include voltage regulation circuits and capacitors for smoothing out voltage fluctuations.
3. Welding Control Circuitry:
   • Controls the initiation and duration of the welding pulse.
   • Typically involves a MOSFET or relay to switch the high-current welding pulse.
4. Current Sensing Circuit:
   • Monitors the current flowing through the welding electrodes to ensure precise control and prevent overheating.
   • Often includes current sensing resistors or hall-effect sensors.
5. Safety Features:
   • Incorporates safety measures such as overcurrent protection, thermal protection, and short-circuit protection to prevent damage to the circuit and ensure user safety.
6. User Interface:
   • Provides controls or indicators for adjusting welding parameters such as pulse duration and intensity.
   • May include buttons, knobs, or a digital display for user interaction.

Operation:

1. Power On:
   • The circuit board receives power from the 12V battery when the welding machine is turned on.
2. User Input:
   • The user sets welding parameters using the interface provided on the circuit board.
3. Initiation:
   • When the user triggers the welding operation, the control circuit initiates a welding pulse.
4. Welding Pulse:
   • The welding control circuitry activates the welding electrodes, allowing a high-current pulse to pass through the metal parts to be joined.
   • The duration and intensity of the welding pulse are controlled by the circuit based on user settings.
5. Current Monitoring:
   • The current sensing circuit continuously monitors the welding current to ensure it stays within safe limits and terminates the pulse when the desired weld is achieved.
6. Safety Checks:
   • The circuit board continuously monitors for any faults or abnormal conditions, triggering safety measures if necessary to protect the circuit and the user.
