Plasma torch
The PT100 plasma torch supplied has the ‘euro style’ power/gas connection
(in this case the gas used is compressed air), pilot cable and switch pins
connections.
All plasma cutting system and torch incorporate a safety circuit to prevent
operator injury when changing consumables etc. This is a simple ring circuit
that breaks the electrical torch switching as soon as the retaining cap is
removed preventing machine operation.
Without such a protection circuit as previously mentioned the open circuit
voltage could be as high as 350V DC at the torch head.
The torch head encompasses a full set of
consumables as shown right, these consumables are
made up of a cooling tube, torch electrode, swirl ring
for gas distribution, cutting tip, retaining cap and if
required a stand off device to ensure the same
distance between tip and material being cut.
