First, thx for your help.
Ehm my problem..i'm going to build a weller mage, atm its lvl 46
Now i want to know whats best lvl for welling?
I asked some of my m8s but unfortunately they told me different lvls

One said 55, another said 64 and the last one said 75+ ..
So i hope, that some of the experienced wellers here, could tell me, whats best, ty!
