Running too cold does seem to be one of my common errors. Even my welds that turn out pretty good are still on the cold side of perfect. It is very rare for me to go the other way.

I suppose that might be in part because too much the other way (hot-wise) pretty much means no metal left in the area to finish welding. So attempting not to vaporize the metal makes me (and I assume many newbs) heat shy.

I have been working on that. Practice, practice, practice.
