Plasma Power Supply parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Input Transformer 1× Step-down and isolation transformer from three-phase mains (400 V) to secondary (80–100 V).
2 IGBT Rectifier 1× High-frequency DC power module with current control feedback from the plasma circuit.
3 Control & Feedback Board 1× Microcontroller monitoring arc voltage and adjusting output current.
4 Arc Starter 1× High-frequency high-voltage (4–8 kV) circuit initiating the arc between electrode and workpiece.
5 Earth Cable & Clamp 1× Heavy-gauge return path from workpiece to power source.
6 Connector 2× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
7 Cooling Fan 1× Thermal fan exhausting heat from the rectifier module.
