Yes any welding supply should have it, its also more properly called Nozzle dip. I think the problem you are having is multifold, dirty hard to clean welds, and the toughness of welding thick to thin, overhead, out of position is just not easy, skill/practice helps, but its still tough.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
