Hi Bob, For now I'll assume you have your torch adjusted for a neutral flame. If not heres your first problem. What is probably happening is your overheating your base metals. It should take about 1 mintute to form a weld puddle. Another problem is your base metal is too dirty. If your not using a flux then the base metal has to be clean, grind or sand to remove scale/rust/dirt/etc.
Depending on how dirty even flux will have a problem without precleaning. You also need to preclean your filler rod. Emery paper works well. When you add filler rod don't move the rod to far out of the outer flame cone area when not in use as it will oxidize. This will cause prosisity within the weld puddle. If your weld puddle face looks concave when completed then your not adding enough filler rod. Add enough filler rod for a convex weld puddle face but no more than 1/16" convex above the base metal. See if this helps and if not post back again and we'll continue.
