Aut / ON / OFF
Factory setting: Aut
Aut ... The cooling unit cuts out 2 minutes after the end of the plasma
process
ON ... The cooling unit remains permanently ON
OFF ... The cooling unit remains permanently OFF
IMPORTANT!
If the cooling unit has the "Thermostat" option fitted, the
return-flow temperature of the coolant is constantly checked. If the re-
turn-flow temperature is less than 50 °C, the cooling unit cuts out auto-
matically.
C-t Cooling time
Time from when the flow sensor is triggered until the "no | H2O" service
code is output
For example, if there are air bubbles in the cooling system, the cooling
unit will not cut out until the end of this preset time.
5 - 25 s
Factory setting: 10 s
IMPORTANT! Every time the plasma power source is switched on, the
cooling unit carries out a test run for 180 seconds.
HFt High frequency time
High frequency ignition: Time between HF impulses
0.01 - 0.4 s / EHF (starting with external ignition tool)
Factory setting: 0.01 s
IMPORTANT! If there are problems with sensitive equipment in the im-
mediate vicinity, increase the HFt parameter up to as much as 0.4 s.
PrI Delayed ignition for immediate high frequency start
OFF / 0.1 - 1 s
Factory setting; OFF
If a time is entered for the PrI parameter, arc ignition is delayed by this
amount of time: trigger signal - high frequency applied for the period of
time - arc ignition
