Welding task selection
It is only possible to change the basic parameters when no welding current is flowing and any
possible access control is disabled > see 4.4 chapter.
The following welding task selection is an example of use. In general, the selection process always has
the same sequence. Signal lights (LED) will show the selected combination.

4.2.1.1 Hotstart
The hot start function improves the arc striking.
After striking the stick electrode, the arc ignites at the increased hot start current and decreases to the set
main current once the hot start time has elapsed.
For parameter setting, > see 4.2.3 chapter.
A = Hot start current
B = Hot start time
C = Main current
