Spare Parts of an Air Plasma Cutting Hand Torch

The torch will have a power/gas connection (in this case the gas used is air), pilot cable and switch connections. All plasma cutting system torches should incorporate a safety circuit involved to prevent operator injury when changing consumables etc. This may be a simple ring circuit that breaks any electrical switching as soon as the retaining cap is removed or could be an air valve which closes when the retaining cap is removed preventing operation. Without such a protection circuit as previously mentioned the open circuit voltage could be as high as 350V DC at the torch head end which is very dangerous.

The torch head will encompass the torch electrode, swirl ring for gas distribution in the correct manner, cutting tip and retaining cap.
