 Approximately 1.9 grams of iron works well (seven pellets).
-The pellets need to be melted into one big blob.

-Give yourself 30 minutes for this task. Be patient during the melting, it takes time for the heat to spread from the hot spot. Let all the iron all reach the same temperature before deciding if you need more electron current.

-If the electron current is too high, you might see glowing sparks ejected from the melt. Like the sparks that shoot out of a camp fire.
