welding cast iron is not reccomended although it can be done,myself i have always had the best luck by preheating the cast iron to almost cherry red then using a low hydrogen electrode such as 7018 which is fairly common,there is also an electrode known as inconel which contains the alloy nickel,but its hard to find and very expensive
