: An STM32 series processor manages the user interface (LCD and rotary encoder), monitors input/output voltages, and executes the energy-tracking algorithm.
: The system includes a 250ms hardware watchdog to prevent accidental continuous firing, fused overvoltage protection, and undervoltage lockout to protect the source battery. Power Supply Requirements kweld schematic
The kWeld is built for high-demand hobbyist and professional lab use. Specification 4V – 30V DC Maximum Current 2000 Amperes Max Weld Energy 500 Joules User Interface LCD screen, rotary encoder, and beeper Material Capability Up to 0.3mm pure nickel; 0.1mm copper (sandwich) 3. Power Supply Configurations : An STM32 series processor manages the user
: Large copper bus bars are integrated into the PCB to distribute massive currents with minimal resistance. This mechanical design is critical for maintaining the high current levels required for welding pure nickel strips up to 0.3mm thick. Specification 4V – 30V DC Maximum Current 2000
