Pre-heat the material. Your problem is that it takes several inches of weld before there is enough heat in the base metal for things to go smoothly. This is the same reason that TIG is the preferred method on aluminum, you use the TIG torch to heat the aluminum at the start of the weld before adding filler rod.
