5.1.3.6 Welding parameter ignition time "tZn" diagram
NOTE
In the ignition time, the wire feed continues to run at creep speed after the arc is ignited;
the ignition behaviour is improved with the optimum setting.
The factory setting is that the ignition time is already optimally preset for various materials. The
process described below is always used if there is a pause between welding processes of not
less than 1.5 seconds.
