I am learning how to use 7018 actually, different from the 6013 I have been mostly burning (plus some 99 Ni on iron, but that is another story

7018, I like the clear view of the puddle, but not the fragility when you stick
I seem to understand that : 1 you create the "puddle" , then
2 as soon it is large enough you move a little the electrode out so it does not stick,
3 then you come back (immediately), make a short arc, and begin to pull/attract the puddle from its edge, looking for the size you obtain to regulate the speed,
I did find that only that way I could obtain a very short arc about 1,5 mm , the arc is almost not visible. Not too much slant (more 80 than 70) so the bead does not grow up , and the gas shield is still efficient.
Eventually a little zig zag (is a little turning allowed ?) First I did stop and go (until the puddle have grown enough) but the bead is not straight enough on its edges (may be I should only go slower)
If I did allow a longer arc, even well tense, I had a tendency to stick often, may be because it gives too much heat to the electrode so the metal flow too fast . What do you think ?
My goal is to be capable of making thin beads, with minimum height (so to weld with 3 4 beads in angle for instance)**Thank you in advance for your thoughts.
I use 30 arc force and 20 or 30 hot start (more does not seem to agree with the graphite start)
Not too much problems with restart after a little filing or using a martyr
*I did cook the electrodes then store them in very dry box at 16 17% relative moisture, (silicate bags) they seem to burn regularely that way
Thanks for your tips I will appreciate them
