8.5 THC arc voltage measurement test.
If everything has been connected correctly, the first test of the manual
cut can be performed. To do this, please make a long simple "manual" cut
and read the measured voltage that will be presented in the main program
window under ARC :
. Lay the straight material about 2-3mm thick on the table.
REMEMBER TO HAVE GOOD CONTACT BETWEEN THE MASS
CLAMP TERMINAL AND THE MATERIAL TO BE CUT. Set the
appropriate cutting parameters for the material such as current, pressure,
etc. ( according to the plasma source's instructions). In the cutting
parameters, specify the cutting speed for the material ( according to the
source manual ) and disable the THC height control :
Position the torch nozzle approx. 3mm above the material, switch on the
plasma with the SPACE key and immediately start the movement ( X or Y
) with any arrow of the keyboard. After releasing the arrow key the plasma
will be switched off.
