5.15 Optimising the ignition characteristics for pure tungsten electrodes
This parameter can be used to improve the ignition characteristics of “pure tungsten electrodes”, for
example. The parameter is a %-value (factory-set to 20) and is changed across all JOBs.

Select Ignition Characteristics parameter
The signal lights for the selected electrode
diameter and ignition current AMP% flash for
approx. 5 seconds. The parameter value can
be optimised on the rotary transducer during
this time.
Set parameter value
Increase parameter value:
more ignition power
Reduce parameter value:
less ignition power
5.15.1 TIG automatic cut-out
If the arc does not ignite after starting or if the arc is interrupted when the torch is moved away,
an automatic cut-out occurs after 5 sec.
The HF, gas and open circuit voltage (power unit) are switched off.
If RINTX1x or BUSINTX1x are in use the automatic cut-out is regulated by the settings made with
the software PC300.net.
