NOTE!
If there are problems with sensitive equipment in the immediate vicinity, increase
the HFt parameter to a maximum of 0.4 s.
STS
Special two step - special 2-step mode for HF ignition after touching the workpiece
Unit -
Setting range OFF / 1
Factory setting OFF
Ignition sequence, when the STS parameter is set to 1:
- Touch the workpiece with the tungsten electrode
- The short circuit detection on the power source is triggered
- Lift the tungsten electrode off
- After 300 ms the gas pre-flow time begins
- HF ignition is initiated
- End of welding due to arc break
C-C
Cooling unit control (option)
Unit -
Setting range Aut / ON / OFF
Factory setting Aut
Aut Cooling unit is switched off 2 minutes after the end of welding
ON Cooling unit is ON all the time
OFF Cooling unit is OFF all the time
IMPORTANT! If the cooling unit is provided with the optional "thermostat", the coolant re -
turn temperature is checked continuously. If the return temperature is less than 50 °C, the
cooling unit is switched off automatically.
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.
Unit s
Setting range 5 - 25
Factory setting 10
IMPORTANT! Every time the power source is switched on, the cooling unit carries out a
test run for 180 seconds.
HFt
High frequency time - high frequency ignition: Time interval between the HF pulses
Unit s
Setting range 0.01 - 0.4 / OFF / EHF (start with external arc starters, e.g. plas -
ma welding)
Factory setting 0.01
