Welding parameter ignition time "tZn" diagram

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.
Legend with an explanation of symbols can be found in the MIG/MAG function sequences /
operating modes chapter.
