orch Operating Principle

Once the torch is filled with the proper fluid, the power supply is connected, and voltage

is applied to the cathode (the ON button is pressed), the operator can cause the torch to

produce an arc by pressing the start button briefly This results in the cathode shorting to

the torch nozzle As the start button is released, an electric arc is produced between the

cathode and nozzle Arc energy heats the nozzle, which in turn heats the evaporator,

which causes the fluid to heat and turn into steam Steam flows toward the nozzle outlet

Escaping from the nozzle, steam compresses the

electric arc Arc compression increases arc temperature Compressed electric arc heats

the steam to ionization temperature

under internal pressure . - . bar

The system has two modes of operation

MODE I is the indirect arc mode An electric arc is produced between cathode and

nozzle The plasma jet is the only vehicle that transfers energy to the workpiece

material

MODE II is the direct arc mode The conductive workpiece is part of the cutting (welding)

circuit and the electric arc is produced between the workpiece and the cathode inside

the plasma jet This causes a significant increase in the amount of thermal energy

transferred to the workpiece

assembly (see

Section 6.6.2) ethanol mixture

in accordance to

(0 4 1 2 ).

The device includes two torches, which are structurally identical. One with a green label

is initially equipped for cutting and the torch with the red label for welding. These torches

are interchangeable by changing the nozzle, by adjusting the cathode

, and by replacing the working liquid (water or water/ ). We

recommend using each torch its respective color-coded labels.
