Abstract
A plasma torch that includes an electrode having an exterior surface and a tip having an interior surface spaced apart from and facing the exterior surface of the electrode. A process gas flow channel located being located between the exterior surface of the electrode and the interior surface of the tip. A thermoelectric cooler having a cold plate and a hot plate is disposed between the exterior surface of the electrode and the interior surface of the tip with the cold plate being thermally connected to the exterior surface of the electrode. According to some implementations, electrical power is deliverable to the thermoelectric cooler only up electrical power being supplied to the electrode.
