The welders where I work weld a lot of cast iron by either stick or TIG. I have not personally seen them MIG weld cast. I know a lot of people will braze cast. I have no preference on any of the above, but I agree that a slow preheat and a very slow cool down is the key. Where I work, they have built a special heater out of old natural gas furnace parts. Their cool down container is filled with floor dry.
