I do tack but a bit further apart. I like to see how much the metal is moving as I go and with the closer tacks I end up not seeing as much movement. The metal is going to move and if I have a good eye on it I can sometimes get a good couple inch long weld before I have to stop and planish.
With the closer tacks I feel the need to weld shorter and planish more frequently because I am not as able to see the metal move.
Just my two cents though. I have seen people run a bead the whole panel length and planish after but I don't seem to have that much luck.
