WAVE-SHAPED BALANCE
8. DC Frequency Pressed.
By pressing function keys 31 e 32 the luminous indicator is
position at 26 - Picture 1 Page 4.) ; then by activating the knob
30, the frequency for the DC TIG pressed is set up.
The frequency can be regulated between the following ranges:
a) Between 0,3 Hz and 1Hz with a 0,1 Hz step.
b) Between 1 Hz and 250Hz with a 1 Hz step.
9. Descent Slope.
By pressing function keys 31 e 32 the luminous indicator is
position at 27 - Picture 1 Page 4.) ; then by activating the knob
30, the time is set up in seconds either to reach the final current
welding in the Four Times mode, or to cancel the nominal
current welding in the Two Times mode.
The value range is between 0 and 10 seconds.
10. Final Current
By pressing function keys 31 e 32 the
luminous indicator is position at 28 -
Picture 1 Page 4.) ; then by activating
the knob 30, the
value for the final current on the TIG Four Times mode is set up.
The value range is between I Min and the nominal current welding.
11. Post gas.
By pressing function keys 31 e 32 32 the luminous indicator is
position at 29 - Picture 1 Page 4.) then by activating the knob
30, the time length for the final gas flux is set up in seconds. The
