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 coolant 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.
UPS
UpSlope - continuous increase of starting current up to welding current I
1
Unit s
Setting range 0,0 - 9,9
Factory setting 0,1
Eld (TransTig only)
Electrode diameter
Unit mm in.
Setting range 0 - max. 0 - max.
Factory setting 2,4 0.1
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
NOTE! If there are problems with sensitive equipment in the immediate vicinity,
increase the HFt parameter to a maximum of 0.4 s.
The special HF ignition indicator remains lit as long as a value has been specified
for the HFt parameter.
If the HFt set-up parameter is set to "OFF", no high frequency ignition takes place at the
start of welding. In this case, welding starts with touchdown ignition.
Pri
Pre Ignition - delayed ignition with immediate high frequency start
Unit s
Setting range OFF / 0.1 - 1
Factory setting OFF
If a time value is set for the parameter Pri, the welding arc is ignited with a delay corre-
sponding to this value: Press the torch trigger - high frequency is activated for the speci-
fied duration - the welding arc is ignited
