The heart of the machine that "chops" the DC into high-frequency AC (often between 20kHz and 100kHz).
A high-voltage, low-current oscillator circuit that ionizes the air, allowing the arc to jump from the tungsten to the workpiece without physical contact. Tig Welder Inverter Schematic
Converts incoming AC mains (110V/220V) into high-voltage DC. The heart of the machine that "chops" the
Always disconnect power and manually discharge large filter capacitors before touching the circuit. They can hold lethal charges for long periods after the machine is unplugged. Tig Welder Inverter Schematic
Operating at high frequencies allows this transformer to be much smaller and lighter than traditional 60Hz transformers. Output Rectification & Smoothing:
