I'd like to attempt a small TIG welding project - welding cast iron to steel.

What TIG settings would you recommend?

What type of filler rod is best?

thanks a bunch

I am new to TIG welding, currently working with aluminum. For the most part I am primarily practicing with 3/16" aluminum, fairly small pieces of angle and flat stock - around 2-4" length angle and approx 4"x"4" flat stock. The welds are solid, strong, I feel I am doing well...
