Optimising The Ignition Characteristics For Pure Tungsten Electrodes; Tig Automatic Cut-Out - EWM TETRIX 1002 DC SYNERGIC Operating Instructions Manual

5.3.2

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.
Control element
5.3.3

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 3 sec. The HF, gas and open circuit
voltage (power unit) are switched off.
