Torch Explorer: Non-Transferred vs Transferred Arc

Two common DC arc torch architectures — defined by where the arc is allowed to land. Compare them, and push the relative power up.

Schematic teaching model of a DC thermal-plasma torch. The mode distinction is the real one — non-transferred: the arc burns cathode-to-nozzle inside the torch and only hot gas exits; transferred: the workpiece becomes the anode and takes the arc current directly — but geometry, plume shape, melt-pool size, and temperatures are illustrative and not to scale. Thermal torches are equilibrium-leaning plasma near or above 10,000 K in the core: the opposite design goal from the cold, non-thermal discharges elsewhere on this site.
