OPERATION
AIR PLASMA CUTTING TECHNOLOGY
A plasma cutter operates by passing an electric arc from an
electrode (Fig. 5-5) through a gas such as nitrogen, air, argon
or oxygen that is forced through the air diffuser (Fig. 5-4) then
a constricted nozzle (Fig. 5-2). The shield cup contains and
directs the initial air/gas (Fig. 5-6). The gas temperature is
raised until it becomes superheated plasma (Fig. 5-3). The
plasma cuts through the metal while carrying the electrical
charge. The charge transfers to the metal and ground cable,
completing the electrical circuit.
The electrode has an insert of
tough high conductive
material such as hafnium and
cerium (Fig. 5-1). The nozzle
and electrode require
periodic replacement due to
erosion with use. Clean, dry
air improves the lifespan of
the electrodes and nozzle. A
plasma air filter is
recommended.
OVER-VOLTAGE
This equipment has an automatic voltage compensation
function, which enables the unit to maintain the voltage within
the given range. In case that the input voltage or amperage
exceeds the stipulated value, it is possible to damage the
equipment’s components. Please ensure your primary power
supply is correct (See Specifications).
DUTY CYCLE
The cutting unit’s duty cycle rating defines how long the operator
can cut before allowing the cutting unit to cool. The duty cycle is
