: An STM32 series processor manages the user interface (LCD and rotary encoder), monitors input/output voltages, and executes the energy-tracking algorithm.
The kWeld operates as a high-current, low-voltage electronic switch. The "schematic" is essentially a path of least resistance designed to handle extreme bursts of power.

: An extremely rugged array of MOSFETs serves as the primary switch. These are designed to handle currents up to 2,000 Amps with an internal resistance as low as 120ВµOhm .
The core of the circuit is its ability to measure real-time energy (Joules) rather than time. It monitors the current and voltage drop across the weld to shut off precisely when the target energy is reached. : An STM32 series processor manages the user
The heart of the KWeld design is its power source. While many DIY welders repurpose microwave oven transformers (MOT), the KWeld schematic is designed to utilize a high-current capacitive discharge system.
Today, we are taking a closer look at the to understand what makes this device tick and why the engineering behind it is so effective. * Input voltage for welding: 4V - 30V
This is the most ingenious part of the schematic. The KWeld measures current using a (4-wire sensing) across a very low-value shunt (or the internal resistance of the system itself).
