Plasma Power Source parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Inverter Module 5 parts 1× IGBT inverter chopping mains DC to high frequency for a compact, regulated cutting output.
2 Output Rectifier 1× Diode stack and choke smoothing the inverter output into a steady cutting current.
3 HF Igniter 1× High-frequency or blow-back starter ionizing the gas to strike the pilot arc.
4 Torch Cooling Loop 3 parts 1× Pump, radiator, and coolant circulating through the torch to carry off arc heat.
5 Power Supply 1× Unit that converts mains or battery input into the regulated DC voltages a machine's electronics and actuators need.
