E - FLAT ELECTRODE FITTING, CONICAL PIPE
There fittings are used to implement the plasma processes :
- oxygen
- nitrogen
- argon-hydrogen
This fitting works with :
- flat electrodes whose type depends on the plasmagene gas used, and the
diameter depends on the cutting intensity,
- a barrel with a gas vortex flow,
- cone nozzles marked with an intensity value which corresponds to the maximum
intensity that the nozzle can withstand without destruction. This intensity also
generally corresponds to the value of the cutting intensity displayed on the
autonomous cycle.
Destruction or rapid wear of electrodes Marking and use of flat electrodes
- Verify the type of electrode according to the
plasmagene gas used.
W
= Tungsten nitrogen
argon hydrogen
- Check the condition of the gas vortex barrel.
- Check the cooling circuit.
H
= Hafnium oxygen
CUTTING APPEARANCE (CLEARANCE) :
The forced rotation of the gas (vortex) gives a special shape to the cut.
Generally, the gas rotation direction is carried out clockwise (clock direction, right).
The gas rotation (vortex) causes an angle difference on the sides cut.
The right rotation of the vortex results in the right side of the kerf being
practically vertical and the left side inclined.
Because of this, it is important that the direction of the movement be chosen
so as to obtain the inclined side of the scrap side.
