PRESTOJET 45 – cut
After pressing the button in the torch:
Preflow – purge flow before ignition of the pilot current
– 2s (unalterable).
Pilot current – maximum 3s, if it does not touch the
material or the button in the torch is released, the pilot
current will automatically turn off.
Cutting current – proper cutting – lasts as long as the
button in the torch is pressed.
Postflow – gas flow after cutting – time depends on
the current – see Table 3.

PRESTOJET 45 – grid
After pressing the button in the torch:
Preflow – purge flow before ignition of the pilot current
– 2s (unalterable).
Pilot current – maximum 3s, if it does not touch the
material or the button in the torch is released, the pilot
current will automatically turn off.
Cutting current – proper cutting – lasts as long as the
button in the torch is pressed.
Grid time – sustaining the pilot current, possible only
the button in torch is pressed. Enables the transition
between the materials to be cut. Adjustment range:
1 – 5s.
Postflow – gas flow after cutting – time depends on
the current – see Table 3.

PRESTOJET 45 – gouging
After pressing the button in the torch:
Preflow – purge flow before ignition of the pilot current
– 2s (unalterable).
Pilot current – maximum 3s, if it does not touch the
material or the button in the torch is released, the pilot
current will automatically turn off.
Gouging current – lasts as long as the button in the
torch is pressed.
Pilot – sustaining the pilot current (grid process). Is
only possible when the button in torch is pressed.
Postflow – gas flow after gouging – 15s (unalterable).
