Avesta 309-16 will weld cast iron , just like 7018 welds carbon steel. It will also weld carbon steel to cast iron or stainless to carbon. It runs down hill, side ways and flat. never tried it over head. Best rod ever for dis-similar metal. Spendy but it is worth every penny. Another option would be TIG with 309-16 fill wire.
